Ag-Grid Energy – Aerobic Digester

Agricultural & Organic Waste into Renewable Energy

Company Description:

Ag-Grid Energy has a vision to convert agricultural and organic waste into renewable energy, compost and support local area practices that lead us towards a sustainable environment. Ag-Grid Energy intends to finance, build, own (jointly), operate the waste to energy conversion facilities in US.

Technology Description:

As the world has become increasingly concerned with the environment, the federal government, more specifically, the Environmental Protection Agency, has cracked down on farmers, creating stricter regulations regarding environmental impacts.  

Among these are the management of water runoff and air pollution, i.e. the release of greenhouse gases. Such regulations put tremendous pressure on existing farming practices. Ag-Grid Energy can help farmers with enhanced water and manure management. Using the proven technology of anaerobic digestion, they hope to bring about change in the farming community by:  

1) constructing an anaerobic digester on-site or nearby

2) generating electricity to be given back to the farm at no cost

3) providing a solid digestate material to be used as animal bedding

4) supplying a liquid digestate to be used as fertilizer on the farm.  

Through the use of Anaerobic Digestion, Ag-Grid Energy also provides a beneficial alternative to land-filling/incineration by taking away the excess food waste from large food waste producers in accordance with the Commercial Food Waste Disposal Ban and plan use the nearly 2.1 million tons of heavily-organic spent mushroom substrate (SMS) produced annually around Kennett Square, PA as a feedstock as well.
