Natural processes with state-of-the-art technology

Organics Recycling and Compost Manufacturing

We Do Composting Right

Our commercial composting facilities boost natural processes with state-of-the-art technology to recycle and process a wide variety of organic materials at our all-weather indoor facilities 24/7, 365 days a year.

Sustainability Powered by Science

Our facilities offer many advantages over more traditional disposal and composting operations.

We compost many different types of organic materials, including biosolids and residuals, and more.

Our process is based on the scientific enhancement of the natural biodegradation cycle. This technology delivers superior results and rapid throughput for greater cost-effectiveness. Annual processing capacity is 10 times that of a windrow operation with the same footprint.

The McGill process can handle special applications like sludge drying or volume reduction. We also provide comprehensive facilities solutions including package plants and design, build, operate capabilities.

Controlled conditions ensure year-round processing. This delivers dependable service for our intake customers and ready volumes of consistently high-quality products for our compost customers.

McGill’s transportation fleet is able to match your operation’s production schedule with reliability.

Inside a McGill Composting Facility

Our sites are designed to be unobtrusive and blend in with the communities and neighborhoods we serve. Behind that facade is a modern, industrial-scale compost manufacturing plant utilizing the latest technologies and scientifically advanced processes.

At all facilities, wet feedstocks are off-loaded into indoor, concrete bunkers where an extraction system collects the air and sends it on to the biofilter to help control odors. High-moisture materials are dropped onto a bed of very dry amendment or compost to absorb free liquid. Dry feedstocks may be stored on a small, outdoor pad until needed for blending.

Tractor-trailer rigs are pressure washed after off-loading to eliminate odors and minimize track-out. The concrete apron is sloped so wash water drains into the pit for use in the composting process. Non-toxic detergents and cleaners keep our microbes safe.

Our proven blending processes rely on efficient, reliable, and flexible bucket blending over mechanical mixers and conveyor systems.

Residuals and by-products blended to prescribed ratios based on available feedstocks are placed inside concrete-encapsulated bays designed with a special floor to accommodate our aeration system. Sensors are placed and the doors are closed, totally encapsulating the admixture. The composting mass is not touched again until the computer tells us the process is complete.

Aeration delivers oxygen to the microbial populations responsible for biodegradation and removes the heat generated by their feeding activity, maintaining temperatures within the specific range required for happy microbes. Air is pushed up and through the composting mass, while extraction fans pull air off the pile and away from work zones within the building. Process air is piped to a biofilter.

Computers at all facilities use a proprietary system to regulate the aeration system and monitor temperatures, which are continuously recorded to confirm processing goal attainment for regulatory reporting. The time:temperature ratio of our process mimics pasteurization, even though no external heat is applied.

Screening equipment customized to meet McGill specifications results in a compost with even consistency batch after batch. After screening and curing, our compost is ready for market as an EPA Exceptional Quality (EQ) product.
