The future utilization of MSW is dependent on the readiness of biodegraded waste or the rate of bio degradation.
How the rate of biodegradation can be accelerated economically.
Which factors are involved in controlling the rate of biodegradation?

Dear Mohsin,
Anaerobic sludge digestion in oxygen free system can be possible economically because of production of methane. You can use methane in these kind of system for thermofilic digestion. We can contact for future information.
understanding he various components of organic fraction of MSW regionally is of significance in selecting the type of treatment.
Then optimise the selected treatment technology.
Thank you all.
Can anyone please list out the factors affecting the rate of biodegradation of MSW?

Various factors are involved in affecting the rate of bio-degradation of MSW like composition of MSW, organic waste present in the MSW plays more important ,moisture content present, and presence of other non biodegradable waste like plastics, glass etc
factors affecting the rate of biodegradation of MSW?
1. Organic matter (OM%) present in wastewater
2. Moisture Availability
3. Available Oxygen
4. Temperature
5. Toxicity
Also, loading rate, pH, retention time, substrate type. Cheers
Integrated BioChem is building a pilot plant to demonstrate that its patented technology both rapidly process biomass and do so at a profit. These tests will be for 90 days using a single cycle per day. The process is capable of 3 cycles per day. At the laboratory level we have demonstrated to ability to process the equivalent of 300 kg of biomass per 1,000 liters of reactor per day. Depending on the nature of the biomass, this means the process could process up 900 kg per 1,000 liters of reactor per day. In these tests the nutrient mix will be supplemented. Again depending on the nature of the biomass, the engineering estimates with 3 cycles per day are between 1,200 and 1,500 kg of biomas per day per 1,000 liters of reactor. Attached is a paper that describes the products produced by the process and the economics. The numbers have been cofirmed by independent laboratories.
Dear Mohsin ,
Integrated Solid Waste Management (ISWM) provides a framework for the development of a sustainable MSW service, which can take place with the use of a range of collection, transport and treatment options. It takes an overall approach to creating sustainable systems that are economically affordable, socially acceptable and environmentally effective. An integrated solid waste management system involves the use of a range of different treatment methods, and key to the functioning of such a system is the collection and sorting of the waste. It is important to note that no one single treatment method can manage all the waste materials in an environmentally effective way. Thus all of the available treatment and disposal options must be evaluated equally and the best combination of the available options suited to the particular community chosen. Effective management schemes therefore need to operate in ways which best meet current social, economic, and environmental conditions of the municipality.

The municipal solid waste can be economically biodegraded using anaerobic digestion.The rate of anaerobic digestion can be increased by a number of factors such as ph, Hydraulic loading etc.
Can we think of any small system (small scale). for houses and restaurants. to recycle their organic waste and produce, the useful products like gas and fertilizer.
Which problems can be faced if we plan to design such bioreactor at small scale and user friendly as well.
The major point of concern in these biodigestors s is the technology transfer and understanding.The rate of microbial growth and its parameters is of great importance.
it will depend on type of bacteria we used for this process and growth of bacteria in bio-reactor. it should produce bio-fertilizers which can help poor farmers.
Dear All, thank you for your contributions to this discussion. More to come!
In the modern future, do you think that these systems will become a necessity, or become the part of kitchen? This will produce free energy for the house or a restaurant and the fertilizer can be utilized for organic food.
There are some successful cases can be identified for organic waste management (through home gardening, composting and biogas production)
