Material Recovery Facility

A material recovery facility (MRF) is an intermediate facility where non-compostable solid waste is temporarily received and sorted so that useful materials can be recovered. It connects waste collection with recycling, further processing and safe disposal, rather than functioning as a dumping site.

Place in the waste-management chain

An MRF receives dry or non-compostable waste after collection. Source segregation should separate biodegradable wet waste from the dry fraction, while the MRF undertakes further sorting to improve material recovery.

• The facility aggregates waste from different collection routes and provides temporary storage under controlled conditions.
• It complements source segregation but should not be treated as a substitute for segregation by waste generators.

Core functions

• Workers or mechanical systems sort waste into recoverable streams such as paper, plastic, glass and metals.
• Recovered materials may be cleaned, compacted or baled, depending on the facility, and dispatched to authorised recyclers or processors.
• Non-recyclable combustible fractions may be sent for suitable processing, while inert material and processing rejects proceed to authorised disposal facilities.
• The facility may involve authorised waste pickers and informal recyclers in sorting and recovery, as recognised by the Solid Waste Management Rules, 2016.

Environmental significance

By separating marketable materials from residual waste, an MRF improves resource recovery and reduces the quantity requiring transport, treatment or landfilling. Effective operation requires fire safety, worker protection, controlled storage and timely removal of recovered materials and rejects.

• MRFs support the waste hierarchy by prioritising recovery and recycling over disposal.
• Their performance depends on reliable segregated collection and viable linkages with recyclers and processing facilities.
