Abstract:

Composting is considered as an effective and sustainable food waste treatment technology from the perspectives of volume reduction, stabilization and releasing the pressure on landfills. Community composter is a decentralized composting facility in fed-batch operational mode which is usually being installed in the backyard of institutes, hospitals, housing estate etc. to handle the food wastes generated daily. Albeit numerous operational issues including high initial acidity and oil content, poor decomposition and odor generation are commonly encountered in these facilities, which make it diff

Abstract:

Composting is a sustainable method to deal with huge amount of daily organic waste due to its robustness and easy operation. However, food waste (FW) as the main material in composting has disadvantages such as the heterogenous properties, high foreign matters contamination, high moisture content, low C/N ratio, poor structure, low porosity and high acidity during the initial phase of composting. These shortcomings not only influence degradation efficiency but also cease the composting process. Therefore, a bulking agent is required to increase the porosity and adjust the moisture content as w

Abstract:

Fertilizer P fixation and fertilizer N losses in soils may be reduced through additions of polyphenolic compounds. The influence of ammonium lignosulfonate (NH$ sb4 sp+$-LS) on triple superphosphate (TSP) efficiency was investigated in a soil incubation study using three Quebec soils and in a growth bench study using one soil. For the incubation study, soils were analyzed for pH and P extractability, as a function of NH$ sb4 sp+$-LS rate and time. In the growth bench study, TSP and NH$ sb4 sp+$-LS were applied at varying rates and corn (Zea mays L.) dry matter yields and nutrient compositions

Phosphate and ammonium removal from waste water by adsorption using inorganic natural sorbents has been identified as a promising technology. The advantages of this methodology are associated with its availability and effective low cost. Some natural and synthetic zeolite materials have been used for the individual phosphate and ammonium removal from aqueous solutions. The zeolites revealed high affinity for ammonium removal. However, some modifications stages are indispensable to enhance their oxyanionic sorption capacity to achieve high phosphate removal ratios. So, it is highly desirable t

Abstract:

The number of biogas plants in Germany is increasing from 3,711 in 2007 to 8,075 in 2016. In these biogas plants, it occurred more than 50 Mt digestate. Therefore, several investigations are started to use digestate as organic fertiliser mostly for field crop cultivation. Experiment with tomatoes was carried out were digestate was used as a supplement to the growing media in an amount of 5%, 15%, and 25%, compared with a treatment of mineral fertiliser and lupine wholemeal. The tomato yield was highest in the treatment with mineral fertilisation, the yield with 25% digestate was only a little

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 meas

Abstract:

The waste from olive oil production is a valuable source of nutrients that has the potential, when used well, to be a useful organic amendment to aid crop growth. It does have some drawbacks with potential phytotoxicity due to being likely to have a high amount of phenols present and a high conductivity. The waste from olive oil production used in these trials was composted with different animal manures to produce a number of products with different characteristics. In some of the trials a replacement form of organic amendment in the form of chicken manure was used instead. In addition to thes

Abstract:

This dissertation thesis deals with the development of technology which could tackle two major issues related to biogas plants. These issues concern the insufficient use of waste heat from biogas combustion and its subsequent processing. It also concerns the use of the fermentation residues which are formed in large quantities and whose use is restricted by law. Based on a literary search of separation methods, a vacuum evaporator was selected as the most suitable technology. Its advantages include its simple construction, operational reliability and robustness, low costs of thickening medium

Abstract:

Sustainability has become a critical element in the way business strategies are designed. Many organisations have adopted best management practices and the corporate governance of modern companies have been aligned not only to look at profits but also to take into consideration the impacts that they have on people and on the planet. There has recently been a substantial acceptance towards renewable energy sources worldwide, however anaerobic digestion of bio-waste into bio-energy has been around for decades and has not seen the equivalent recognition in South Africa.

Abstract:

Vermicomposting is an eco-friendly waste management strategy. Its successful performance necessitate that key functioning parameters like earthworm stocking density, nutrient enrichment be established for each target waste/waste mixture. One main target waste mixture in South Africa, and in the University of Fort Hare in particular is waste paper mixed with cow dung and rock phosphate (RP) for phosphorus (P) enrichment. This study was carried out to address the following specific objectives, to determine (i) the effect of Eisenia fetida stocking density on the bioconversion of cow dung waste p

Abstract:

Immense amounts of waste are generated daily by our society, and the management of these streams is a critical societal function. Part of this work is reusing and recycling materials with attractive properties, which is also an imperative step towards circular material flows. Although, the reuse of waste-based resources entails a conflict between efficient use of resources and minimal environmental toxicity, which hampers the reuse. The labeling of a resource as waste also makes using or trading the resource problematic, both regarding regulations, but also concerns from the society regarding
