Planning to compost MSW Organics to sell fertilizer?
You better think twice!
Because 'Biodegradable' doesn't mean harmless.
Did You know
that MSW Organics can be highly contaminated?
Hi, I am Heinrich Seul, Founder of CBE German Waste Project Advisors Bangkok.
Today, I will give you 4 Solutions on what to do with MSW Organics.
Contrary to general belief only half of your project's MSW might come from
households. All other materials are collected at public space, factories, hospitals, offices, markets ...
It means MSW Organics have been in intense biochemical reaction with harmful, infectious materials. In waste bins, on collection trucks, dumps.
MSW Organics are often highly contaminated with
- faecial coliform bacteria
- salmonella
- human enteroviruses
- protozoan parasites
- hormone disruptive chemicals like Bisphenol A from plastics
- heavy metals from plastics, textiles, electronics
- carcinogenic fine dust from tires, exhausts and break pads in street sweepings
