Anaerobic Digesters

Anaerobic digestion (AD) is a biological process in which microorganisms break down biodegradable material in the absence of oxygen. This process is used industrially and domestically both to manage waste and produce circular products including:

  • Biogas can either be combusted to generate electricity and heat, or processed into renewable natural gas (RNG) for injection into the natural gas distribution network or for use as transportation fuel.
  • Digestate can be treated to create liquid and dewatered digestates – high-quality products that benefit agricultural land.

Processing organic wastes via AD reduces odours at operating facilities because they are entirely enclosed. All process emissions are captured as biogas which is either combusted or upgraded into RNG, resulting in over 99% odour removal. With the heightening scrutiny on odour performance, the expanding demand for renewable energy and the increasing number of economic programs supporting renewable energy forms, AD treatment processes are now a viable solution for treating organic waste streams.

Aerobic Composting

Aerobic composting is a long-term, proven technology for responsibly managing organic wastes while generating beneficial end products like compost. There are a wide variety of composting processes, from simple outdoor windrows to mechanized, enclosed in-vessel composting facilities with extensive product refinement capabilities to vastly improve finished compost quality.

In areas without access to wastewater treatment or natural gas distribution, or with limited incentives for generating renewable natural gas (RNG), aerobic composting is generally the most cost-effective solution for management of organic wastes.

AIM has been involved in the technology selection and design of aerobic composting facilities dating back to 2005. We provide the selection and supply of material handling; composting process; ventilation and odour control; and shredding, screening and product refinement technologies. As specified in your project’s scope, AIM can assume process guarantees that may be required.

While AIM’s primary technology focus is on fully enclosed in-vessel aerated static pile composting facilities that process municipal source separated organics (SSO), we can provide technology and process support for other composting technologies, including aerated outdoor fabric covered windrows or mobile modular containerized composting processes.
