Abstract

This study explore how to convert solid wastes into a valuable resource fertilizer its subsequent utilization. Improper solid waste disposal poses a major threat to the environment and high risks to human health. Most of these wastes are biodegradable and can be converted into valuable resources. It aimed to develop technology on solid waste composting for the production of organic fertilizer determine its results for vegetable production and its effect on some soil physical properties. Combined solid waste (buffalo manure: rice hull ash) at a ratio of 2:1 proved to be the best combination. When the solid wastes are composed mainly of rice straw and leaf litter, as well as their combination, the decomposition process is prolonged from 30 days to between 60 and 75 days. Economic analysis says that initial investment of US$490 for the MRF can be recovered within 2.68 years. Pure application of organic fertilizer and compost showed great potential in intensive small scale organic-based vegetable production.

Objective

The project aimed to promote proper waste management.

It aimed to develop and disseminate technology on solid waste.

To determine efficacy with which organic fertilizer generates major nutrients.

Literature View

Solid waste generated by unabating increase in human populations is one of the major

problem confronting future generations.

WHO’s survey on waste generation indicated that an individual generates an average of 500-

800 gm of waste in one day.

Through conversion of biodegradable wastes into organic compost or organic fertilizer partly

solves waste disposal problems.

Methodology

The project involved four phases described as follows:

Phase I. Information dissemination on proper solid waste management

Phase II. Development/improvement of composting technology

Phase III. Evaluation of produced organic fertilizer and compost tea as major

sources of plant nutrients for intensive vegetable production

Phase IV. Technology promotion and utilization

Tentative Conclusion

The economics of organic fertilizer production from solid waste indicate an initial

investment of US$490.

For one cycle (27 to 30 days) with a production of 100 bags, gross sale was

US$300 with total expenses of US$113.41.

The initial investment for the MRF can be recovered within 2.68 years.

Limitation

The technology requires drying of soil prior to treatment.

Pyrolysis is not effective in either destroying or physically separating in organics from the contaminated medium.

Volatile metals may be removed as a result of the higher temperatures associated with the process, but they are not destroyed.
