Abstract:
Phrasamutjedee Municipality, Samut Prakan Province, Thailand, currently faces many problems in
solid waste management, especially costs of collection and transportation. From the municipal solid
waste component analysis, there was about 62% biodegradable waste and 27% recyclable waste.
This component ratio conforms to the regional solid waste component ratio reported by the
Pollution Control Department of Thailand (64% biodegradable waste and 30% recyclable waste).
Separation of biodegradable waste and recyclable waste can reduce the cost of solid waste
management and also extends the lifetime of landfills. Moreover, biodegradable waste can also be
used for the production of enzyme ionic plasma (EIP) and organic fertilizer. From the survey of
Phrasamutjedee Municipality's waste components, the biodegradable waste was approximately
10,700 kilograms per day (about 2,000 kilograms derived from fresh-food markets). This study
investigates biodegradable waste reuse for production of enzyme ionic plasma. When the
biodegradable waste is mixed with molasses, effective microorganisms and water, it will produce
about 2,570 liters per day of enzyme ionic plasma per day. Byproduct of enzyme ionic plasma
(mixed with dung, rice bran, husks and organic matter) could be used to produce about 5,670
kilograms of organic fertilizer per day. If Phrasamutjedee Municipality uses its biodegradable waste
for the production of enzyme ionic plasma and organic fertilizer, the collection and transportation
costs of the garbage will be reduced, and Phrasamutjedee Municipality can also benefit from the
enzyme ionic plasma and organic fertilizer.
