Abstract:
The objective of this study was to evaluate the effect of including guava wastes in the feed on the performance and carcass yield of broiler chickens. An experiment was carried out with 300 male Cobb strain chicks, in a randomized complete design with five levels of waste and five replications. A reference diet based on corn and soybean meal and four feeds with 3, 6, 9 or 12% guava waste were evaluated. The feed intake, weight gain and feed conversion were assessed weekly; the weight at slaughter and the weight and yield of eviscerated carcass, carcass without feet and head, breast, drumstick, thigh, wing, back, edible viscera and abdominal fat were assessed. The inclusion of guava waste in the feed promotes performance and carcass yield similar to that obtained with the feed based on corn and soybean meal, therefore this agro-industrial by-product can be used at levels of up to 12% in feeds for broiler chickens.

Abstract:
The aim of this study was to find out the potential of agricultural and food industry wastes as the constituents of pig feed to improve pigs’ performance and to reduce the feeding cost. This study was conducted at Manokwari Regency, West Papua Province. The agricultural and food industry wastes were collected from two traditional market, and four small-scale food industries. All materials used as feed were proximately analyzed to determine their nutritional values. Average daily gain, feed consumption and feed coversion ratio were taken to determine the pigs performance. Feed cost using local market prices was estimated in knowing the ability of agricultural and food industry wastes to substitutes commercial feed. The result of this research indicates that the use of agricultural and food industries wastes as an alternative components of pigs’ feed to substitute the commercial feed do not reduce the pigs’ performance and production. Among three feeds that use of agricultural and food industry wastes, feed with the combination of 75% waste and 25% commercial feed had the best feed conversion ratio, namely 2.36. On the other hand, a mixture of 25% wastes and 75% commercial feed was the most economic one, and able to reduce the feeding cost of grower pig up to 48.00%.Key words: agricultural waste, food industry wastes, grower period, pig, feed

Abstract:
Due to overfishing and the use of one-third of wild fish catches for feeding farmed fish and livestock, there is a strong need for alternative sources of suitable proteins and lipids in fish feeds. Small freshwater worms of the species Lumbriculus variegatus can be such a source based on their high protein content, variable lipid content and amino acid pattern. In addition, their production can be combined with waste reduction, as they can be grown on safe organic wastes. In this article, it was investigated whether fatty acid (FA) profile of the worms changed with feed source. Profiles of worms grown on different feeds were highly similar, but also reflected profiles of feeds. Data suggest that the worms are capable of poly-unsaturated fatty acids bioaccumulation. The worms converted different organic wastes (fish faeces and food industry sludges) with an efficient feed conversion ratio of ~1.8 (dry to wet weight) resulting in a theoretical production of 0.1-0.14 kg of fish per kg of waste. Worm composition resembles that of other live feeds and the biomass contains important FAs. Safety of organic non-feed waste streams for worm production should be further evaluated.

Abstract:
This paper reviews the current state of bio-processing of market waste to poultry feed in Uganda. A focus was put on crop wastes since previous studies have indicated that, they contribute the biggest percentage (about 90%) of the total organic waste generated in markets. These wastes majorly comprise of fruits and vegetables like mangoes, pineapples, jackfruit, watermelon, cabbage among others. They are usually in form of residual stalks, leaves, peels, and damaged/rotten crops. Crop wastes are rich in various bioactive and nutraceutical compounds, like carotenoids, polyphenols and dietary fiber. The wastes are a major worthwhile raw material and present feasible solutions to the problems of poultry feed scarcity and high costs associated with the conventional feed stuffs. This transformation can be achieved by developing appropriate technologies for valorization of wastes by nutrient enrichment. In concern to this, solid state fermentation (SSF) and rearing insects and earthworm using crop wastes are the promising novel technologies. High value added products/feeds can be produced through microbial fermentation of crop wastes. Insect protein can also be produced to replace the expensive silver fish and soybean protein sources. The review indicated that, the technologies have not been fully cherished within the country’s poultry feed industry. All the attempts and work done are still under research and pilot scale level. However, the on-going endeavors are continued widely to better conversion technologies in order to produce products that are safe for poultry feeding. Lastly, the limitations and strategies for processing poultry feed from market waste are reviewed.

Abstract:
Feed waste in pork production sheds can amount to substantial economic losses. No simple methods exist to quantify this waste, which commonly ends up in the effluent stream. Monitoring piggery effluent might offer producers a practical alert solution for feed waste losses. We investigated piggery effluent pH as a potential marker of feed waste, given that most feed substrates and breakdown products are acidic whereas effluent is alkaline. To explore this prospective relationship, we constructed simulated effluent streams comprising faeces, urine and feed. These waste components were acquired from a commercial batch grower shed, at four different times over the 12-week growth cycle. In laboratory settings (25°C) we used the collected wastes to simulate the two stages of typical flushing piggery effluent systems: (1) Faeces + urine + feed waste accumulation in flushing channels, and (2) flush water mixing with these wastes in an effluent collection sump. We repeated the exercise for a one-off sampling event at a sow facility. For all events, at the grower and sow facility, the pH of the simulated effluents yielded exponentially decreasing relationships with increasing feed waste level (P < 0.05). For the grower facility we applied each of the four laboratory-derived relationships to the farm’s sump effluent pH, which was measured during each of these sampling events. The predicted feed waste levels were commensurate with estimates of feed waste for the same facility derived from alternative, time intensive approaches reported in other studies. Further work is needed to transition the promising results uncovered here into an alert system to help farmers improve profitability and minimise waste.

Abstract:
In Morocco, the food waste fraction constitutes a large part of the total municipal solid waste generated. In order to promote this fraction as a feed source for poultry, a study was carried out to evaluate its digestive and metabolic effects, as well as its nutritional value on broilers. Indeed, comparative tests were carried out on two separate batches of small broilers fed, successively, with a commercial compound feed (CCF), and a feed prepared in the laboratory using kitchen waste as a substitute (LPF). The results obtained throughout the rearing period revealed the feasibility of the valorization of food waste as a substitute promoted in the poultry feed sector. In addition, the prefabricated feeds gave the same feed consumption index (1.03), compared to the commercial compound feed applied in the same rearing farm, while the weight gain index results were more advantageous for FPL. The study demonstrates the valorisation of feed waste as a new substitute for poultry feed.

Abstract:
The tuna waste in Manokwari has an economic potential that can be used as fish meal animal feed or fish feed. The aim of this study was to determine the chemical contents of tuna waste flour, examine of tuna waste meal, determine the feed test impact to the tilapia growth, analyze the impact of feed to water quality and analyze the feed manufacturing businesses. The study was conducted for six months (January to June 2015) at UD Madurasa. This study used, a completely randomized design with five treatments, there were feed A (control) and four test feeds formulated using tuna waste flour and bran (feed B, feed C, feed D and feed E). The feeds were tested using tilapia sized 5-8 cm and weighted 9-10 g in average (belo phase), then a 750 belos were used and allocated into 15 containers (50 belos / container). Feed was given twice a day in the morning (7:00 a.m. to 08:00) and afternoon (16:00 to 17:00) for six weeks. The feed amount was 5% of the body weight. The results show that tuna waste flour contain nutrients over the nutritional needs by tilapia. The tested feed has nutritional value better than feed A. Feed A has the highest efficiency and value of relative growth of 24.56% and 92.79%. Feed C has an efficiency of 22.83%, Feed E (20.37%), Feed B (19.30%) and Feed D (17.82%), also the growth of relative feed values of C (87.14%), Feed E (64.69%), Feed B (63.04%) and Feed D (55.53%). The variance analysis was not difference, however all feed gave same effect on tilapia growth. The tested feed did not pollute the water and categorized as 2nd and 3rd of water quality. It is assumed that this business is properly to be run with breakeven point will be achieved when sales reached to 8 kg (Rp 130,000.00) or at 4.5 months.

Abstract:
Organic phosphorus (P$ sb{ rm o}$) in farm animal wastes must be mineralized to inorganic P for subsequent plant use. This study was conducted to determine if feed additives affect P$ sb{ rm o}$ mineralization, manure decomposition, and plant growth. Feed additives in aqueous systems affected the P mineralization of inositol hexaphosphate by phytase and of adenosine monophosphate by alkaline phosphatase. Pronounced effects were produced by bacitracin and both enzymes and by neomycin on phytase. Feed additives in dairy cattle (Bos taurus L.) manure produced effects on microbial activity as measured by gas production that differed from those produced on fecal phosphatase activity. Additives applied directly or with manure to Ste. Rosalie clay, Greensboro loam, or silica sand had no effect on barley (Hordeum vulgare L.) yield but did produce additive, rate, growth medium, and manure dependent effects on plant P concentration and soil phosphatase activity. Therefore, each feed additive must be independently evaluated to determine its effect on biological systems.

Abstract:
Finding an alternative to fishmeal and fish oil in animal feeds has been a topic of increasing interest due to the pressures being put on the ocean’s fisheries and the increasing world demand for animal protein. An often-overlooked source of nutrients is in the form of food waste. One third of all food produced globally ends up in landfills, wasting a huge amount of nutrients and embodied energy that could otherwise be redirected towards productive use. This study investigated the feasibility of feeding Hermetia illucens, the black soldier fly larvae (BSFL), grown on urban food waste, and Lemna minor, a species of duckweed, to tilapia in a recirculating aquaponic system as a compound feed. The study compared the growth of two groups of 58 tilapia over 44 days; one group was fed commercial pellets and the other a compound feed composed of BSFL and duckweed. The group fed the commercial pellets achieved heavier weight gain than the group fed the experimental feed but both groups resulted in steady weight gain and had similar mortality rates. Feeding the experimental feed composed of BSFL and duckweed to tilapia in an aquaponics system is an effective method of diverting food waste from the landfill and further research should be done to optimize this process.

The focus of this thesis was to analyze the least cost of producing rations for ducks in three age categories from a mixture of conventional feed ingredients and three different processed food waste products and to examine the financial and economic feasibility of establishing an industrial plant to produce these food waste products in the Montreal region. The first part of the thesis was investigated through the use of a linear programming model. The effect of recognizing the variability of protein levels in the various feed ingredients was examined through the use of chance-constrained programming.<br>The second part of the thesis was examined using economic and financial analyses for the investment. The basic plant requirements to produce the three processed food waste products were the same, however energy costs were different for the three products. Revenue was generated from tipping fees and the sale of the three processed food waste products. (Abstract shortened by UMI.)

Abstract:
Four experiments were conducted with crab processing waste. Addition of 1.5% propionic/formic acid prevented degradation up to 14 d. Desirable fermentation was achieved when 32% of the treated crab waste was ensiled with 32% straw, 16% molasses, and 20% water with or without .1% microbial inoculant. The pH of the silage was lowered and high concentration of lactic acid was observed. Use of .2% NaOCl or .4% H₂O₂ retarded spoilage of crab processing waste up to 7 d. Ensiling of the treated waste (32%), straw (32%), molasses (16%), and H₂0 (20%) indicated that the chemical used in preservation enhanced fermentation. Addition of .4% NaOCl and 1.5% acetic acid to the crab processing waste retarded degradation up to d 4. The trimethylamine (TMA) concentration and NH₃ evolution were highest for the untreated waste while the lowest concentration for TMA and NH₃ evolution were observed for the NaOH-treated waste. Addition of 1% NaNO₂ or combination of .4% NaOCl/CaOCl (1:1, w/w) preserved the waste for up to 10 d. The evolution of NH₃ and H2₂S, and TMA concentration were lowest for the waste treated with 1% NaNO₂. Apparent digestibility of DM, organic matter, CP, energy, NDF, ADF, cellulose and hemicellulose decreased linearly (P<.01) with level of crab waste-straw silage in diets containing 0, 50, and 100% crab waste-straw silage. Nitrogen retention increased linearly (P<.05) with level of crab waste-straw silage. The apparent absorption was higher (P<.01) and retention was positive (P<.05) for Ca, Mg, Na, K, Cu and Fe with sheep fed the highest level of crab waste-straw silage. Daily gain, feed efficiency and carcass characteristics tended to be higher for steers fed 30% crab waste-straw silage, dry basis. The flavor and overall desirability of cooked meat were not adversely affected by feeding up to 30% crab waste-straw silage, dry basis. Modifying the existing methods of quantifying chitin showed that initial decalcification or deprotinization of the samples with chemicals are not necessary. Similar values were obtained for chitin when ADF/ashing method was compared to the ADF/deacetylation method. These methods prevented loss of chitin during preparation. Digestibility of chitin was higher (58%) for sheep fed 100% crab waste-straw silage compared to the value of 37% in sheep fed 50% crab waste-straw silage. When ADF/ashing method was used in quantifying chitin, higher disappearances were obtained for samples containing 100% crab meal kept in the rumen or incubated in vitro for 72 h.<br>Ph. D.

Abstract:
Microalgae have a variety of commercial applications, the oldest of which include utilisation as a food source and for use in wastewater treatment. These applications, however, are seldom combined due to toxicity concerns, for ethical reasons, and generally the requirement for cultivation of a single algae species for use as a feed supplement. These problems might be negated if a “safer” wastewater such as that from agricultural and/or commercial food production facilities were to be utilised and if a stable algae population can be maintained. In this investigation preliminary studies were carried out using an Integrated Algae Pond System (IAPS) for domestic wastewater treatment to determine the species composition in the associated High Rate Algae Ponds (HRAPs). The effect of different modes of operation, continuous versus batch, on nutrient removal, productivity and species composition was also investigated. Furthermore, indigenous species in the HRAP were isolated and molecularly identified as, Chlorella, Micractinium, Scenedesmus and Pediastrum. Additionally, the effect of the nor amino acid, 2-hydroxy-4-(methylthio)-butanoic acid (HMTBA) and its Cu-chelated derivative, on the growth and biochemical composition of Chlorella, Micractinium, Scenedesmus, Pediastrum and Spirulina was investigated. Species composition in the HRAP was stable under continuous operation with Micractinium dominating > 90% of the algae population. Under batch operation the population dynamic shifted; Chlorella outcompeted Micractinium possibly due to nutrient depletion and selective grazing pressures caused by proliferation of Daphnia. Higher species diversity was observed during batch mode as slower growing algae were able to establish in the HRAP. Nutrient removal efficiency and biomass productivity was higher in continuous mode, however lower nutrient levels were obtained in batch operation. HMTBA did not significantly affect growth rate, however treatment with 10 mg.L-1 resulted in slightly increased growth rate in Micractinium and increased final biomass concentrations in Chlorella, Micractinium and Spirulina (although this was not statistically significant for Micractinium and Spirulina), which are known mixotrophic species. Algae treated with Cu-HMTBA, showed reduced final biomass concentration with 10 mg.L-1, caused by Cu toxicity. Biochemical composition of the algae was species-specific and differed through the growth cycle, with high protein observed during early growth and high carbohydrate during late growth/early stationary phase. Additionally, 0.1 mg.L-1 HMTBA and Cu-HMTBA significantly reduced protein content in Chlorella, Micractinium, Scenedesmus and Pediastrum. In conclusion, operation of the HRAP in continuous culture provided suitable wastewater treatment with high productivity of an ideal species, Micractinium, for use in animal feed supplementation. This species had 40% protein content during growth (higher than the other species tested) and dominated the HRAP at > 90% of the algae population during continuous mode. Addition of HMTBA (> 1 mg.L-1) to algae cultivation systems and those treating wastewater, has the potential to improve productivity and the value of the biomass by enhancing protein content. Overall, the co-utilisation of microalgae for wastewater treatment and the generation of a biomass rich in protein, for incorporation into formulated animal feed supplements, represents a closed ecosystem which conserves nutrients and regenerates a most valuable resource, water.

Abstract:
Food waste accounts for about 1/3 of the municipal waste generated in Hong Kong. Using food waste as major ingredients to produce fish feed pellets could ease part of the disposal pressure on the existing landfill sites. The present study focused on the use of food wastes and feed supplements (prebiotic fibres and Chinese herbs) for rearing freshwater fish (grass carp, bighead, mud carp and Nile tilapia) in Hong Kong. Two isonitrogenous formulations, Food Waste Diet A (FWA), consisted of 53% cereal, 10% fruit and vegetables, 8% bone meal, 4% other food waste, 10% fishmeal, 15% corn meal and Food Waste Diet B (FWB), consisted of 25% meat, 28% cereal, 10% fruit and vegetables, 8% bone meal, 4% other food waste, 10% fishmeal, 15% corn meal were manufactured by Kowloon Biotechnology Ltd, were used as feeds for rearing grass carp, bighead, mud carp and Nile tilapia. The essential amino acid profiles and proximate compositions (crude protein, crude lipid and total phosphorous) of the two food waste based feed pellets were compared with other common feed items, including Napier grass, rice bran, breads, noodles, soybean dreg (remains of soybean after juicing for soybean milk) and the commercial feed pellets (Jiefeng® 613). Jiefeng® 613, FWA and FWB possessed 5.83%, 5.76% 5.79% (% protein) of lysine, which could satisfy the dietary requirements of both grass carp and Nile tilapia. Results indicated all the fish feed pellets possessed sufficient essential amino acids and suitable proximate compositions (crude lipid, crude protein, crude fibre and non-fibrous carbohydrate) for both grass carp and Nile tilapia. A field trial was conducted using the three feed pellets (Jiefeng® 613, FWA and FWB) to study their effects on fish growth (grass carp, bighead and mud carp) as well as water quality. FWA that possessing a higher P content (2770 μg/g feed, while control= 967 μg/g feed and FWB= 1942 μg/g feed) favoured the growth of plankton and led to better growth of bighead carp (in terms of length gain, wet weight gain and productivity), while grass carp fed with FWB showed significant better growth (in terms of length gain, wet weight gain, productivity, feed conversion ratio, specific growth rate and protein efficiency ratio), probably due to the relatively lower amount of carbohydrate (24.2%) and CHO:L ratio (1.83) than Control and FWA. Mud carp grew equally well in ponds fed with the three diets. FWB was subsequentially selected for further feeding experiments. A laboratory feeding trial was conducted to study the effects of feeding grass carp and Nile tilapia with FWB on their growth performance in terms of relative weight gain (RWG), feed conversion ratio (FCR), specific growth rate (SGR) and protein efficiency ratio (PER), and protein digestibility. Both fish fed with FWB showed similar growth performances to groups fed with control diet (Jiefeng® 613), while grass carp showed impaired protein digestibility when compared to group fed with control diet. FWB supplemented with 0.3% of vitamin-mineral premix (VMP) significantly improved the growth performance of both fish species and protein digestibility for grass carp. Results suggested that FWB incorporation with VMP would be necessary as it significantly enhanced growth of the fish. Four dietary supplements (inulin, mannan-oligosacharride, huangqi and goji, at the rates of 0.2% or 2%, w/w) were incorporated into FWB for further enhancing fish growth as well as non-specific immunity of grass carp and Nile tilapia. Grass carp fed with 0.2% and 2% inulin, 2% MOS and 0.2% goji, and Nile tilapia fed with 0.2% goji had significantly enhanced growth (RWG, FCR, SGR and PER). Both prebiotic fibres and Chinese herbs boosted the tested non-specific immune parameters (total serum immunoglobin, serum bactericidal activity and anti-protease activity) of both species. Among all the dietary supplements, 0.2% goji appeared to be the best supplement for both grass carp and Nile tilapia as it significantly enhanced the growth among all experimental diets. Grass carp and Nile tilapia fed with 0.2% showed about 10% and 30% higher RWG, 10% and 30% lower FCR value, respectively, than groups fed with other experimental diets. Moreover, all the tested non-specific immune parameters (total serum immunoglobin, serum bactericidal activity and anti-protease activity) were significantly enhanced when compared with the groups fed with control diets (Control and FWB without supplementation) . The present study demonstrated the feasibilities of using food wastes incorporated with feed supplements (prebiotic fibres and Chinese herbs) to enhance fish growth and immunity, for the sustainable development of Hong Kong inland aquaculture.

Fermentation lasted 72 hours at 30C. after which crude protein level in the substrate increased from 5% to 13%. Factors found to be important in determing the efficiency of the fermentation process included fermentable sugar content of the medium, nitrogen and mineral levels, initial temperature, PH, moisture, agitation of the medium, and size of particles constituting the substrate. Protein quality of the fermented peel was evaluated by PEP assay and a PER value of 0.78 was recorded. It is suggested that a low level of total amino acids is the major contributory factor to this low PEP value. Total amino acid level measured 5.75g per 100g fermented peel waste.<br>Master of Science (Hons)

Abstract:
Municipal solid wastes (MSW) typically contain plastic materials, leather, textiles, batteries, food waste and alkalis. These materials are sources of chlorine, sulfur, potassium, zinc, lead and other heavy metals that can form corrosive media during combustion of the MSW in waste-to-energy (WTE) facilities. Chlorides and sulfates, along with fly ash particles, condense or deposit on the waterwall surfaces in the combustion chamber and on other heat exchanger surfaces in the convection path of the process gas, such as screens and superheater tubes. The resulting high corrosion spots necessitate shutdowns and tube replacements, which represent major operating costs. The aim of ongoing research at Columbia University is to gain a better understanding of the effects of fuel composition, products of combustion, and chemical reactions that lead to the corrosion of metal surfaces in WTE boilers. The potential chemical reactions and their chance of occurrence were determined by means of thermochemical calculations of the respective equilibrium constants as a function of temperature and gas phase composition.

Full text
Abstract:
A mathematical model of a mass-burn, waste-to-energy combustion chamber has been developed that includes stochastic representation of the variability of the fuel (municipal solid waste, MSW). The drying, pyrolysis, gasification and combustion processes on the moving grate are governed by several factors such as proximate and ultimate analysis, particle size, moisture, heating value, and bulk density, all of which change continuously. This extreme variability has not been considered in past mathematical models of WTE combustion that used mean values of the MSW properties. The Monte Carlo stochastic method has been applied to provide a time series description of the continuous variation of solid wastes at the feed end of the traveling grate. The combustion of the solid particles on the grate is simulated using percolation theory. The feed variation and the percolation theory models are combined with the FLIC two-dimensional bed model developed by Sheffield University to project the transient phenomena in the bed, such as the break-up of waste particles and the channeling of combustion air throughout the bed, and their effects on the combustion process.

Abstract:
Abstract Up to 1998, spent ion exchange resins have been fed to the incinerator in combination with various other solid combustible wastes at Belgoprocess. However, thanks to sustained efforts to reduce radioactive waste production in all nuclear facilities in Belgium, the annual production of solid combustible waste is now much too small to allow this practice to be continued. Since the incinerator at Belgoprocess is not capable of treating spent ion exchange resins as such, it was decided to adopt the use of foam as a carrier to feed the resins to the incinerator. The mixture is a pseudohomogeneous charged foam, ensuring easy handling and allowing incineration in the existing furnace, while a number of additives may be included, such as oil to increase the calorific value of the mixture and accelerate combustion. The first incineration campaign of spent ion exchange resins in a triphasic foam mixture, in conjunction with other liquid and solid combustible wastes, will be started in January 2000. The foam, comprising 70% by weight of resins, 29% by weight of water and 1% by weight of surfactant will be pulverized in the incinerator through an injection lance, at a feed rate of 40 to 100 kg/h. The incinerator and associated off-gas treatment system can be operated at standard conditions. Belgoprocess is the subsidiary of the Belgian national agency for the management of radioactive waste, known by its Dutch and French acronyms, NIRAS and ONDRAF respectively. The company ensures the treatment, conditioning and interim storage of nearly all radioactive waste produced in Belgium.

Abstract:
Food processors and retailers are under increasing regulatory and market pressure to manage their food waste in an environmentally responsible way. This study analyzes the climate change impacts of several alternatives available for the management of the several food wastes generated in this sector. Four food chain wastes are selected: whey, apple pomace, grease trap waste and bakery waste. Four treatment pathways were analyzed: landfill, anaerobic digestion, land application and animal feed. The results of the analysis showed significant differences among the pathways with climate change impact varying from −621 kgCO2e/t to 1924 kgCO2e/t. Landfilling of food waste resulted in the highest impacts and diversion to feed animals resulted in net benefits. The moisture content of the waste proved to be an important factor while the bio-degradability and nutrient value also had an influence. The combined impacts of diverting food waste from one disposal pathway to an alternative pathway were also considered and data is provided on the optimal pathways for each food waste alternatives.

Full text
Abstract:
Chemical rate and heat transfer theory indicates that the combustion performance and productivity of a moving grate waste-to-energy boiler should be enhanced by means of pre-shredding of the MSW, thus reducing the average particle size, homogenizing the feed, and increasing its bulk density by an estimated 30%. However, the capital, operating and maintenance costs of the shredding equipment should be low enough so that existing or new WTE facilities consider pre-shredding of the MSW. In cases where MSW is transported to a central WTE from a number of Waste Transfer Stations (WTS), pre-shredding may take place at the WTS, thus increasing density and decreasing transportation costs. This is a mechanical engineering study that examined the evolution and present state of shredding equipment since 1994 when the last WTE shredder in the U.S. was installed at the SEMASS facility. The quantitative benefits realized through the pre-processing of MSW by means of modern shredding equipment are evaluated both for the traditional high speed hammermills and the new generation of low-rpm, high-torque shredders. The combustion characteristics of shredded MSW were analyzed and compared to those of the “as-received” material that is presently combusted in mass burn WTEs. The emphasis of the project has been on equipment that can be integrated in the traditional flowsheet of a WTE and serviced readily. The most important criterion in the final design will be that the economic and energy benefits of pre-shredding be clearly greater than the conventional operation of combusting as received MSW.

Full text
Abstract:
In September of 2007, a new 636TPD Municipal Waste Combustor was brought on line at the Lee County WTE Facility in Fort Myers, FL operated by Covanta Energy. This unit was the first new Waste to Energy unit built in the United States in a number of years and included a lower permitted daily average NOx emissions requirement of 110ppm @ 7%O2 while maintaining ammonia slip to less than 10ppm. To meet this new stringent NOx emissions requirement, the boiler was designed with advanced combustion controls including Flue Gas Recirculation combined with a urea based Selective Non-Catalytic Reduction Process to provide a combined NOx reduction of approximately 70% while maintaining the required ammonia slip. The SNCR System provided by Fuel Tech was designed with 3 levels of seven wall injectors installed in the upper furnace. Both boiler load and Furnace Gas Temperature were used as a feed forward control with the CEM NOx signal as a feed back to automatically select the injector levels and reagent feed rates to maintain the targeted NOx while also maintaining ammonia slip control. This paper will outline the design considerations, the details of the process and the operation of the systems on this unit.
