Abstract:

A new process has been developed for efficient anaerobic digestion of the organic fraction of municipal solid waste. The BTA-process comprises pretreatment of incoming waste followed by a three-phase anaerobic biology consisting of acidification, solids hydrolysis and methanization. One main fraction of organic wastes is cellulose causing a diauxie effect during anaerobic digestion. Acidification of the pretreated waste occurs spontaneously, and is not limited by the level of anaerobic microorganisms in the waste. Solid retention time and pH in the hydrolysis reactor have an important influenc

Abstract:

This paper explains the interest in urban organic solid wastes, the relevance of these wastes to municipal solid waste management, the main ways in which organics are reused, and the problem that arise from the wish to ensure safe and effec�tive reuse as part of sustainable development in cities in Romania. Wastes are substances resulting from biological or technological processes that can no longer be used as such, some of which are reusable. Dangerous substances are any substance or product which, when used in apparently non-hazardous quantities, concentrations or conditions, presents a sign

Abstract:

The performance of a small-scale two-phase anaerobic digestion system which processes municipal solid wastes, i.e. vegetable and fruit wastes, was evaluated at mesophilic conditions. An anaerobic digester which required 5 L of fresh cow manure, 5 L of solid waste feed, 5 L each of leachate from the solid waste, and 1 L of anaerobic seeding had been constructed. The volume of the feed solids after digestion has significantly reduced after the operation. The total accumulated methane for a solids retention time (SRT) of 20 days contained useful heat energy amounting to 330.27 KJ.

We performed 28-day mesophilic fermentation of a mixture of pig slurry and primary (raw) sludge from the sedimentation stage of a wastewater treatment plant at a 1:1 ratio. The components and the original and fermented mixture of slurry and sludge were subjected to acid hydrolysis. Dry matter of the solid phase of both components and both mixtures was incubated with sandy-loamy Cambisol at a weight ratio 3:1 at 25°C for 20 weeks; in 14-day intervals lipids, crude protein, hemicelluloses, cellulose, lignin, total nitrogen and hot-water-insoluble solids were determined.

Abstract:

Solid organic wastes were codigested together with sludge of a sewage treatment plant (STP). In the practical part of the study, a plant to pretreat the organic solid wastes provided by local super markets was constructed at the STP of Frutigen, Switzerland. Up to more than 1 cubic metre of wastes was added to the fermenter of the STP every day. Data collected during 14 months of practical works, showed that for raw fruit and vegetable wastes a two step pretreatment is necessary: First the wastes were chopped and afterwards reduced to a size of 1-2 millimetres, in order to get a homogeneous su

Abstract:

Composting is a naturally occurring process that turns organic waste materials like leaves, food scraps, and other organic wastes into a valuable manure that can improve the fertility and structure of the soil by introducing beneficial organisms, humus, and important plant nutrients. By breakdown, this process transforms the organic substance into inorganic and organic components. In recent years, composting received more attention due to pollution concerns. Loss of resources due to the continuous increase in wastes leads to environmental risks. The process of composting is of three types, i.e

Sekondi-Takoradi Metropolis, one of the rapidly expanding cities of Ghana has been facing serious problems with solid waste management. This is mainly due to the lack of available information about the types and quantity of solid waste generation in the area. Hence, the objective of this study was to determine the rate of household solid waste generation and its composition in the aforesaid city. The methodology and procedures for this study were derived from the Standard Test Method for Determination of the Composition of Unprocessed MSW (ASTM D 5231-92).

Organic wastes or bio-wastes are not “waste” but prospective bio-resources. Management of bio-waste by technical methods has become a burning issue in the present time. In the present study cow dung (CD), Mango litter (ML) and Municipal solid waste (MSW) was treated with earthworm Eisenia fetida in different mixture ratios of the substrate. Waste was converted into organic manure along with increase in biomass and number of earthworms. This is supposed to be due to the rich concentration of OC, N, P and microbial population.

The escalating volume of solid waste due to rapid urbanization, population growth, and industrialization poses significant environmental and public health challenges. Improper disposal of solid waste, especially organic and municipal garbage, leads to pollution of soil, air, and water, causing a surge in health risks and ecosystem degradation. Traditional waste management practices are often inefficient, expensive, and time-consuming.
