Abbotsford Compost Facility


CITY OF ABBOTSFORD FOOD WASTE PROCESSING FACILITY

COMPOSTING TECHNOLOGY FOR CLEANER, GREENER COMMUNITIES

Net Zero Waste Inc. was recently successful in its bid to design build, own and operate a food, green and agricultural waste commercial composting facility for the City of Abbotsford. This facility will be responsible for the treatment of organic waste for Abbotsford’s approximately 150,000 residents and provide a vital processing option for other commercial and agricultural wastes produced in the Fraser Valley. Our facility design will utilize an in-vessel design by placing the standard Gore Cover Processing Model inside of a building with secondary biofilter control. Furthermore, through the use of waste heat energy recovery, this site will utilize the high temperatures experienced below our compost piles to provide heat to greenhouses or other indoor agricultural initiatives, further improving the sustainability of the entire operation. Agricultural initiatives already underway by the landowner have always been the primary component of the site operation with hog barns redeveloped to indoor farming and vermicomposting operations. Our compost operation provides a significant opportunity for waste heat recovery, further improving the sustainability of all initiatives while encouraging the construction of greenhouses.

Our Strategy

NetZero Waste has focused its operational strategy around the Gore Cover System which is based on a membrane laminate technology similar to that of the Gore-Tex fabrics used for outerwear and footwear. Installed in more than 150 plants in 26 countries world wide, the benefits of the Gore Cover System include odor reduction of 90-97%; Bio-aerosol Emissions reduction of greater than 99 percent; less than 1 KWH/ton Energy Requirement and a three square feet/ton space requirement.

Proven Results:

The Gore Cover System results in more than a 97% reduction in odour concentrations without the need for bio-filters or expensive facility exhaust fans.

Due to the optimized biological process under the Gore Cover, accelerated High Rate Composting occurs resulting in much higher facility throughput. (400% higher than conventional windrow or up to 9 Tonne/m2 per year)

How it works?

The Gore Cover Traps Odors and moisture ensuring a97% odor reduction from conventional windrow while providing the ideal environment for microbial activity.

 

The simple design of the Gore Cover System allows operations to proceed outdoors and in full view.

Escalating maintenance costs associated with complex mechanical systems used in other technologies are also avoided.
 

 

Gore Cover System Features:

  • Repels water
  • GORE-TEX® membrane Industrial grade tarp
  • Contains odors& humidity
  • Allows CO2 pass through
  • Retains heat
  • Optimizes biological activity

Technology:

The Gore Cover System is classified as an in-vessel composting system by regulatory authorities and provides the following benefits over comparable technologies:

·       Operations: Optimized operations and a reduction of stage treatment and multiple handling requirements (each heap is moved only twice)

·       Utilities: Positive aeration drastically reduces utility operational costs (less than 1kWh of electricity per tonne of compost). The Gore Cover 2Hp blowers are on for approximately 2 minutes every 10. In comparison, “Negative Aeration Systems” must have their blowers on 24 hours a day 7 days a week to prevent negative odour events

·       Layout: Compact design results in a drastically reduced facility footprint and a 400% improvement in throughput from conventional windrow systems

·       Safety: Micro-porous GORE-TEX® membrane results in a microbe reduction of more than 99%

·       Capital Cost: Very Competitive Project Start-Up Capital & Cycle Operation Costs allow the Gore Cover System to provide organic disposal fees well below landfill waste tip fees.

·       Design Ingenuity: This Gore Cover allows a standard “Aerated Static Pile” to become an in-vessel system through the use of the patented membrane cover (This removes regulatory requirements for an enclosed facility)
