Success in Selective Routing Can Help Ensure Clean Recycling Materials in the Commercial Space

June 6, 2016

This innovative sustainable materials management approach involves strategically picking up loads from businesses that generate similar types of discards. The linked article discusses the approach of following simple procedures governing selective routing in the commercial space.

Using a phased methodology, it is possible to turn a high-disposal garbage collection system into a high-diversion recycling system, without incurring additional costs or losing collection revenue. Dumpsters behind shopping plazas and other sites can become opportunities at the center of a thriving materials recovery program.

Take me to the full article.

Minimize Contamination in Recycling

January 25, 2016

For many years source separation was the primary method for recycling. However, technology has changed how recyclables are collected and processed. China, the largest importer of materials for recycling now strictly enforces regulations on importing contaminated materials for recycling into the country. China’s Operation Green Fence puts restrictions on what material China will accept, rejecting materials that don’t meet higher standards of cleanliness; that means rejected materials get buried in a landfill instead of being recycled.

Regardless of the type of recycling program, the biggest challenge here at home is now minimizing contaminated recycling material. Communities are struggling to meet diversion goals and provide materials to local recyclers that are free of common contaminants such as liquids left in containers or motor oil. My SCS team has assisted communities in the last few years to address contamination issues and I’d like to share what works best to kick start addressing the issue at home.

Recycling Assessments: Conduct a visual and physical characterization study to identify contamination levels using one of these two methods for the evaluation:

  • Recycling Routes: Material from front, side, and rear-load trucks are assessed to determine which routes and days of the week contain the largest volume of contamination. This information is used to target geographic areas for implementation of behavior change programs.
  • Recycling Containers: Material from compactor, roll-off, front-load containers or carts are assessed to identify which customers have severe contamination. This information is used to target customers who need additional assistance to clean up their recycling.

Recycling Technical Assistance: Meet with local businesses and perform a walk-through of their facility to collect baseline waste assessment and material collection infrastructure information. This information can then be used to provide customized recycling and composting recommendations, and implementation support such as employee training sessions, providing signage and collateral, referrals, and multi-lingual outreach services.

Review and Analysis of Community Recycling Programs: Review and analyze your recycling program. An environmental engineer can provide recommendations and assessments on how a recycling program can be enhanced to reduce the quantity of contaminated materials. Services typically include everything from examining outreach materials to the flow of the recycling from generation to transport to processing.

Planning and Implementation of Behavior Change Programs: There is value in providing comprehensive programs and explicit outreach materials for increasing the probability of cleaner recycling. Behavior change programs focus on planning and implementing programs that identify key triggers to encourage action in the community. These programs help communicate the importance and value of specific activities to the community and cross any age and cultural barriers.

Contamination is a global problem and is challenging, but there are steps to minimize the problem in your community.
