What is The gore cover system?

Sea to Sky Soils and Composting has focused our operational strategy around the Gore Cover System. This system 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:

  • Odour reduction of 90-97% from conventional windrow
  • Optimization of biological activity through heat and moisture retention
  • Bio-aerosol emissions reduction of  >99%
  • Energy requirement of <1 KWH/ton  
  • Space requirement reduction to 3 sq ft/ton 

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 are also avoided.  


Benefits of the technology

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).


The Numbers

Composting with a GORE® Cover produces ideal composting conditions and leads to increased throughput per composting footprint compared to conventional windrow.
