The high generation of waste in Pakistan (estimated at 55,000 tons/day) has resulted in serious environmental problems. Collected solid waste material are left in depressions and on vacant plots, buried, burned, and dumped in the ocean. To improve this situation, the material was composted and evaluated as a fertilizing material and its effect on the environment. Composting of these waste resulted in the production of good quality materials that can be used as soil amendments and source of plant nutrients. Large amounts of N and K are usually generated and very effective in crop production. Leaching of nutrients was less when compost was applied than mineral fertilizer. The composting of solid municipal waste was observed to be a better option to open disposition.
