McGill has a 30-year track record of using leading technology to embrace and enhance Earth’s natural processes and deliver sustainable and cost-effective organic waste and composting solutions.

Mastering the Science of Compost

Composting is the single most affordable, sustainable method of recovering organic matter and returning it to the soil.

Effective compost manufacture is about biochemistry and the delivery of moisture, temperature, oxygen and food — in the right balance — to create and maintain a processing environment that will encourage the proliferation of the specific microbial populations responsible for biodegradation.

McGill augments this science-driven approach with proprietary technology and systems, resulting in processes and end products that enhance sustainability and save organizations and municipalities money.

Our Compost Manufacturing Process in Action

McGill composting facilities are designed to support the proprietary process responsible for the accelerated biodegradation of target compounds.

The modular design and rapid throughput provide a flexible, adaptable, and cost-effective way of turning all kinds of organic waste into premium compost products.

Dewatering & Transport

McGill picks up and accepts a wide range of biodegradable materials and organic waste, including sludge as part of our mobile dewatering services.

Transportation and intake services are conducted in close partnership with customers to ensure seamless scheduling and logistics.


Our proprietary blending process ensures optimal moisture, porosity, and carbon-to-nitrogen.

Specific formulations are tailored based on the volumes and types of feedstocks processed and depend on their physical and bio-chemical characteristics to deliver the best end product.

Controlled Composting

McGill utilizes McGill-ASP, which is a proprietary modification of the aerated static pile composting process that’s served as the scientific standard for the industry since it was developed at Rutgers University in the 1970s.

Computerized-control of the air delivery and extraction system optimizes composting conditions by maintaining ideal temperatures for the specific microbes responsible for biodegradation.

Curing & Testing

Tight control and automated monitoring of the processing environment reduces the time required to meet regulatory compliance for pathogen kill.

This, in turn, provides cost-cutting, rapid throughput while delivering high quality compost products. Real-time and historic data for each processing bay can be viewed on the computer screen and exported as spreadsheets and graphic visualizations for easy archiving and compliance.

Premium Soil Products

The advanced technology and processing delivers a Class A, Exceptional Quality Compost product that’s STA-certified and ready for a wide range of professional applications.

With pathogen and vector requirements met, the system can be optimized to meet various requirements and process goals. Parameters such as degradation rate, moisture reduction, quality, output volumes, cost, etc. can all be adjusted to meet specific goals.

Good Science, Great Service

Our technologies are designed to enhance control over the natural biodegradation process, allowing our team of experts to tailor processes to meet specific end goals. Facility and process design, process management, automated monitoring and aeration management all allow for greater levels of control.

This control and proprietary technology solution allow our teams to deliver a wide range of bio-based solutions for organic wastes.

Our Competitive Edge

McGill’s compost manufacturing process beings with meeting regulatory standards for pathogen kill and other factors. McGill customizes the design and management protocols for each plant so the finished compost products will meet the quality standards of the intended end use market.

McGill’s moisture reduction services offer a cost-effective alternative to sludge dryers for drying biosolids, sludge and other high-moisture materials. The feeding activity of the microbes responsible for biodegradation generates heat, and moisture is released in the form of steam. No expensive thermal units or centrifuges are required. Sludge can be dried with or without compost production as a processing goal.

McGill’s weight and volume reduction solutions can drive significant savings in transportation costs and tipping fees compared to the original waste stream. Specific savings will vary, but many projects deliver a 50% reduction in both volume and weight.
