Credit 1: Material Recovery Optimization (x points)

Intent:

To encourage the acceptance of a wide range of materials and to promote the production of marketable commodities with the highest percentage of captured product and lowest percentage of residue.

Requirements:

C&D recycling (processing source-separated materials)

Maintain facility uptime of 90% or better and

• Tier 1: Recover [60% or more of the C&D stream.
• Tier 2: Recover [75% or more of the C&D stream.

and/or

Mixed Waste MRF (processing mixed MSW or commercial waste to remove recyclables from the waste stream)

Maintain facility uptime of 90% or better and

• Tier 1 – Recovery of greater than [25% of the waste stream (MSW).
• Tier 2 – Recovery of greater than [40% of the waste stream (MSW).

and/or…

Single stream recycling (processing source-separated materials collected in one bin) Maintain facility uptime of 90% or better and

• Tier 1 – Recovery of at least [40% of the paper, metal, glass and plastic recycling stream.
• Tier 2 – Recovery of at least [50% of the paper, metal, glass and plastic recycling stream.

and/or…

Dual stream recycling (processing source-separated materials collected in two or more) Maintain facility uptime of 90% or better and

• Tier 1 – Recovery of at least [75% of the fiber stream and [50% of the non-fiber stream.
• Tier 2 – Recovery of at least [85% of the fiber stream and [75% of the non-fiber stream.

Potential Strategies:

The facility has and uses the following processing/sorting technology:

• Inspection and potential presort occurs on the Tip Floor.
• Shredding and sizing of materials.
• Positive pick belt sort – A conveyor belt is used to present material to laborers in an effort to recover recyclable materials.
• Negative pick belt sort – A conveyor is used to present material and laborers remove contaminants from the belt prior to recycling.
• Mechanical Screening.
• Optical sorting.
• Magnetic (ferrous metal)
• Eddy Current (non-ferrous metal)
• Air classification
• Robotic
• Quality Assurance/Quality Control

The facility has and uses a daily maintenance program to maintain the effectiveness of the sorting process.

The facility has and uses best practices for the bale storage area.
