James Slattery is the Construction and Demolition (C&D) Zero Waste Coordinator at San Francisco Department of the Environment. In this capacity, James is responsible for regulatory oversight of 12 mixed debris processing facilities, 350+ debris haulers, and more than 30,000 permitted construction activities that generate approximately 1.5 million tons of debris each year. James’ work focuses on resource conservation, debris reduction & material recovery strategies, and environmental action in solid waste management. James has worked with the Department of the Environment for nine years and is excited to share San Francisco’s journey towards Zero Waste.

Advancing Resource Recovery from Construction & Demolition Discards: San Francisco’s Journey

San Francisco has long championed a Zero Waste mindset for construction and demolition (C&D) materials: in 2006, banning direct hauling from jobsites to landfills and mandating recovery; and in 2018, instituting third-party verification requirements for recovery rates and practices at Registered Facilities. Learn how the city of San Francisco (SF) tracks compliance with debris recovery requirements by utilizing third-party verified recovery rates for commingled debris processing facilities, and Green Halo Systems, a fully integrated web-based management system that provides the necessary tools for owners, contractors, project managers and others to transparently comply with debris recovery requirements. SF’s C&D debris recovery policies and programs are currently serving as a framework for policy recommendations under consideration by California’s Statewide Commission on Recycling Markets and Curbside Recycling, as ways to help drive source-separation of C&D discards, while also working to advance recovery outcomes from commingled/mixed debris. The city is fortunate to have robust recycling outlets and progressive practitioners, who are joining policy makers to champion the Advancing Toward Zero Waste Declaration – a commitment to not only slash deposits to landfill but also cut back on generation itself. As such, SF’s policies and programs are expanding to encompass more directly the top two of the 3R’s in the Zero Waste hierarchy: Reduce and Reuse. Learn more about SF’s ongoing efforts to drive greater material reuse and waste prevention outcomes from construction and demolition activities, including infrastructure for material redistribution.

COO

Troy is the COO at Yellowsack which offers a solution for source separation of construction debris at construction sites with lack of space. Troy is responsible for the daily operations in San Francisco Bay area, Los Angeles and Orange County and to make sure that we meet all Governmental requirements and customer needs.

Source separation at construction sites with lack of space

Yellowsack offers the solution of source separation of construction debris at construction sites by utilizing dumpster bags. With our service each dumpster bag can be filled with a source separated debris and the price for the pick-up is dependent on the debris type.

With the dumpster bags, contractors today in the San Francisco Bay area source separate dirt, concrete, wood, brush and yard trimming and mixed debris in different dumpster bags. With our solution we can, in the future, also offer source separation of other debris types, such as gypsum and electronics.

When the dumpster bags are picked up, the truck driver/operator classifies the debris based on his inspection. The debris is then transported to Zanker Recycling Facility, where Zanker inspects and classifies each debris and each Yellowsack dumpster bag is unloaded at the correct site. After the recycling of the debris, contractors can download all documentation at our secured online platform where they have overview of the recycling rate on each debris type. Since the dumpster bags are small and flexible it is a perfect fit for construction sites where today’s solution is to mix all debris in a trailer or one single dumpster.
