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 (see pdf. file attached). 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.
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.

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]
