Gore Cover Experience

Metro Vancouver Gore Cover Project

This trial project was designed to simulate the operation and performance of a full scale Gore Cover Composting Facility treating a 50% food waste mixture. Approximately 260,000 lbs of waste was composted by the process producing a stable high quality compost after only two months. Odour sampling was conducted during the trial demonstrating more than a 95% reduction in ammonia and VOC's.

Following the trial, Metro Vancouver issued a report recommending the sole sourcing of the Gore Cover System as the lowest risk technology worldwide. The Metro board elected not to follow the recommendation of staff and undergo a competitive bid process with 21 competing firms. Net Zero Waste was selected as the preferred proponent for the eastern region, and a 60,000 TPA contract however Metro Vancouver elected not to move forward with our site as we were located on ALR lands. Our 10 acres of unused farm land, sits vacant today and the 50 acres of greenhouses surrounding these lands (previously used to grow tree seedlings) remains unutilized. Our proposal would have captured heat from the compost process to sustain a vibrant greenhouse business on this site.

Chemainus Bio-Solids Gore Cover Project 

Initially started as a trial, a series of batches were tested with various wood waste products until the correct mixture was determined. Modifications to the mixing of the pile and the best operational practices were also made during the processing of the demonstration batches.

Following the trial, Coast Environmental and NZW constructed a small indoor 8,000 tpa facility with small covers and a single aeration trench. A small scale winder was developed to be used in combination with the loader to place and remove the covers.

Environmental Experience

Hawaiian Earth Recycling – Food Waste and Biosolid Composting Facility, Honolulu, Hawaii

Net Zero Waste worked as the design lead for an engineering consortium led by AECOM and supported by design firms local to the island. 40,000 TPA of Biosolids and 80,000 TPA of food waste processing capacity will meet the needs of the island for the next two decades. Downstream farming models exist for this unique market with “up scaling” of compost value to reach boutique markets from sod production to food growth on this 100+ Acre site.

Peninsula Composting – Full Scale Gore Cover Installation Training and Commissioning, Wilmington, Delaware

Expected to be the first of many Gore Cover Systems located on the US East Coast, Peninsula Composting is already planning a biogas expansion in 2011. Scope included installation of the aeration system, programming of the control units and commissioning of the communication systems. Quality control on the existing construction was also provided resulting in design improvements to the 160,000 tpa operation. [$30 million, 06/2009 - Present]

Salish Soils – Fish waste composting facility, Sechelt, BC

Developed in partnership with the Sechelt Nation, NZW trained staff; developed feedstock mixes and provided project engineering and support for project start-up and expansion. A design which places the gore cover system inside of a building allows the facility to be located close to town without negative environmental impacts. This project is processing high concentration fish waste mixtures so as to develop a boutique nutrient rich soil amendment for bagged distribution [$2 million, 09/2010 - Present]

Los Angeles County Sanitation Districts, Consulting Services for the Development of the Westlake Farms Bio-solids Composting Facility, Kings County, California

Front end design and planning was completed for the District's plan to build the largest composting facility in the world with the potential to handle up to 1,000,000 tpa of waste. Involvement included a review of the partially completed internal designs so as to ensure conformance with the Gore Cover Process Model as well as cost optimization for facility construction based on recently completed Gore Projects. Scope included: Site Review and Discussion, Staffing Plan Review, Facility Layout Design Options, Operation and Maintenance Considerations, Equipment Recommendations / Pricing and a Construction Information Package (including detailed installation photos).

NZW involvement saved millions of dollars of project costs through design optimization. The result was significant changes to many areas including the leachate design, conveyor layout and a significant reduction in the amount of infrastructure required for the site.

Sea To Sky Soils Inc. Compost Facility Development

Net Zero Waste partnered with a local operator to establish and permit a successful compost facility which now processes commercial food waste from Whistler and will begin to process curbside SSO from Squamish in the spring of 2015. This operation includes the production of micro-greens and at the source collection from select local producers. Restaurants love the concept of utilizing delicious locally grown micro-greens made in part from their own food waste, for “cradle to cradle” recycling and the highest end use possible of nutrient rich food waste in the region.

Powel River Regional District / Bowen Island Municipality - Compost Facility Feasibility Analysis

Net Zero Waste worked with both of these communities in 2012 and 2014 to aid them with local site investigation and the development of a capital and operating cost estimate for a small scale operation. Both of these locations are implementing a competitive review process in late 2014 and will aim to have a facility built for local recycling in 2015. While these regions have limited tonnages of organics available for recycling due to their populations, existing disposal options include exportation off the island & sunshine coast which elevates disposal costs due to the high cost of ferry transport. The result is that small scale processing is possible above $100/T while still providing savings to the community.
