Our scientifically-enhanced process turns
organic waste into premium compost products

McGill composting facility designs and technologies are based on a scientific enhancement of the nature's recycling process for plant and animal matter.  Creating and maintaining an optimal environment for the proliferation of the specific microbes responsibile for biodegradation provides a level of control which leads to the rapid decomposition of organic material and reliably produces superior compost products every time.

There are three basic steps to the McGill compost manufacturing process:

1. Blending.  Raw feedstocks are blended to prescribed ratios to produce a homogeneous mixture with optimal nutrients, moisture content and pore space. Specific formulations vary and are based on feedstock types, volumes, and physical/bio-chemical characteristics.  Once blended, the admixture is moved to the primary processing area.

2. Processing.  Precise control of processing conditions is provided by a computerized temperature feedback system. Temperature readings from sensors placed inside the blended admixture trigger fans which push air into the floor channels and up through the composting mass to regulate heat.  Holding the self-generated heat at specific time/temperature levels kills pathogens and weed seeds. As a result, all compost manufactured using the McGill process meets or exceeds EPA 503 requirements for designation as a Class A Exceptional Quality compost, suitable for unrestricted end use.

3. Curing and formulation.  Once primary composting is complete,  the material has made the transition from waste to compost product, but this fresh compost has limited market value and is used mostly by farmers. Turning the compost into the quality product required for the professional green industry (turfgrass and landscaping) and environmental uses (erosion control, stormwater management) involves a curing phase and additional materials handling steps.  Curing fully-stabilizes immature compost, while finer screening and blending with other materials like sand, wood chips or topsoil creates products to meet the demands of specific end use markets.
