What is a place where one can separate recyclable materials from other wastes?
Material Recovery Facility
Components of Material Recovery Facility
transfer station, combustion facilities, and disposal site
enumerate transformation processes in recovery
- physical
- biological
- thermal
enumerate 4 components of physical transformation process in recovery part (SWM management)
- Separation
- Size reduction to speed up decomposition
- Densification with the use of shredders
- Foster decomposition afterwards
false about biologicaltransformation processes in recovery
A.also called composting
B.Microorganisms, enzymes and bio-reactors are used to degrade materials
C.Bioreactors should have an optimal mix of helium & nutrients in waste for the microorganisms to work well
C
carbon, not helium
