Zero Waste Week 2018 East Bay Recycling Facility Tour Report

WHAT HAPPENS TO ALL THAT STUFF WE DISCARD?
By Nik Balachandran, Co-founder and CEO, Zabble Inc.
On March 21, an unusually cold and rainy March morning, a bunch of us gathered at the Oakland BART station for the East Bay Facility Tour. We were met by NCRA Board Members and Activities Committee members Alexandra Bradley, Tim Dewey-Mattia and Hilary Near, and staff Juliana Gerber, who drove us there and back through the pouring rain and fed us bagels and other tasty Recycling Update leftovers. Highest and best use!

We visited Independent Recycling Services, DR3 Mattress Recycling and Davis Street Resource Recovery Complex and Transfer Station. Bio-Link Depot, which gives surplus lab supplies and equipment to schools, was also to be on the tour but was closed that day.

The first stop was Independent Recycling Services, a construction debris recovery facility on San Leandro St. in Oakland. We were greeted by the foreman, Billy, who was very courteous in showing us around and explaining daily operations. The facility accepts wood, metals, concrete, plastic, brick, glass, asphalt, gypsum and miscellaneous debris. They do not accept household or hazardous waste.

On a typical day a truck with construction material drives over the scales to weigh the load. The truck then dumps the contents in a common area. The truck is then weighed again on the way out. The difference is used to calculate the tipping costs. A receipt is then furnished with the tonnage disposed and percentage of diversion from landfill, if available. Multiple sorters sift through the pile to pull out valuable materials like uncontaminated concrete, wood (2×4, 2×6…), etc. to add to sorted piles. The management then finds alternative end markets for these goods. The unusable material ends up in a residual discard area. NCRA members had many questions and Billy saw to it that he answered every one of them. One of the members was even able to salvage a perfectly good looking functional piece of furniture.

The second stop was DR3 Mattress Recycling in Oakland. DR3 is a California-based mattress recycling company founded in 1999. They have 3 locations (Oakland, Stockton and Woodland) where they accept drop-offs. They also offer pickup for commercial accounts.

A mattress has 4 recyclable material types; steel, foam, cotton and wood. At DR3, employees place individual mattresses on a waist high platform and disassemble them by hand, also known as deconstruction, in order to maximize the quality of the extracted materials. With this process, DR3 claims that they can recycle 80-90% of a mattress. They then sell bales of clean material. DR3 processes around 800 – 1,000 mattresses a month.

The NCRA group enjoyed taking part in an impromptu competition for the fastest deconstruction times where members took turns completely taking apart a mattresses. Overall, we took with us a good understanding of the different components in mattress recycling.

After that we made a brief stop at the San Leandro Habitat For Humanity ReStore, the nonprofit home improvement store that sells donated new and used furniture, home accessories, building materials, and appliances at a discounted price. We roamed around the store and explored their offerings. It was a good reminder to donate before discard if possible.

Our last stop was at the Waste Management’s Davis Street Resource Recovery Complex and Transfer Station (DTST), one of the most sophisticated material recovery facilities in the country. We met with C&D Diversion Manager, Erika-Alexandra Solis and her team who graciously gave us a tour of the 10 acre facility. (We also learned that Ms. Solis was a recipient of the 40 under 40 Award at this year’s Waste Expo.) NCRA organizers treated us to more delicious leftovers and Vietnamese Bahn Mi sandwiches. Jay Ramos, Sr. District Manager also talked with us for a short while on the plan to sort residuals.

DSTS accepts organics, C&D, recyclables, bulky items like appliances, mattresses, tires, reusable items such as household goods – which are sent to St. Vincent De Paul and trash which is sent to Altamont Landfill in Livermore. Random audits are conducted at different stages to flag inappropriate or contaminated items in the different streams. Materials that cannot be recovered for reuse, recycling or composting are headed to the Altamont Landfill in Livermore. A Waste Management Earth Care Center is located within the premises offers compost and mulch in multiple dyes for professional and household use. It was mentioned that the MRF recycling rate at the facility is 75%.

On my way back in the BART, I reflected about the complexities of the discard management system with all the different material types, their respective handling process and end markets, only for a new cycle to begin. The rain had now abated and the sun was pushing its way through the dark clouds. Perhaps, it’s just a co-incidence that this intricate system made more sense now.
