Problem: Improper disposal directly affects public health, causes pollution as well as affects global warming. In most towns, a company usually takes the task of collecting garbadge from people's homes which they then dispose of usually in landfill. Those living in remote areas or where the roads are inaccessible (which accounts for a large percentage of the population) have to find ways of doing away with their own garbage. They usually bury it, incinerate or use as manure in farms. Otherwise, they just dump it into streams, streets or unused land. Need means through which people can increase rate of household refuse (which accounts to up to 60% of daily trash produced in each home per day)decomposition in their own yards or some nearby community area. Bacteria/ enzymes to be used should procuce no odours, be non-pathogenic grow and reproduce quickly and be readily controlled. Also, what would contain the garbage/bacteria mix?
Bio-Enzyme products for waste digestion MOMAR bio-enzyme products assist natural decomposition. properties: produce no odours, are non-pathogenic, grow reproduce quickly, can be controlled. enzymes added include lipase, protease, cellulase and amylase. Could not find the organism which had been modified to carry out this process. Product used mostly in drains.Bacteria supposedly liquify the waste and then digest that material, but pictures shown to describe process not very encouraging. How do we apply to large scale organic systems? Containment used would be that simailar to aerobic composting. Simply built, well ventillated shallow brick tank above ground level. levels of CO2 produced could be quite high though. Non-pathogenic strains of Actinomycetes which is a natural decomposer could be used. How do we genetically modify?
