Environmentally compatible integrated food and energy production system

Abstract

The present invention relates to the collection of food and energy production units with attendant processing units into an integrated system capable of substantially boosting the efficiency and economics of food and energy production while greatly reducing the impact on the environment. In a preferred embodiment of the invention, the system and process further includes sufficient land area for crop production and uptake of nutrients and water.

Problems solved by technology

While straining environmental management goals, these facilities contribute to the readily available, high quality, low priced food products enjoyed by US citizens.

CAFOs typically generate significant quantities of solid wastes (manures), wastewaters, and atmospheric emissions and these materials are increasingly creating an environmental barrier for continued expansion of the CAFO industry.

Irrespective of the conventional treatment alternatives selected, CAFOs and their associated treatment systems thus require significant amounts of land to operate.

Agricultural runoff is the primary water pollution problem in the United States.

Over-application of animal waste to cropland has resulted in manure nutrients polluting surface and ground water systems, adversely impacting water quality throughout the country.

Wet distillers grains and solubles are denser and more costly to transport than dry distillers grains and dried solubles due to water content.

Also, the wet distillers grains rapidly spoil during storage or transport.

The consequence is that there is a significant cost associated with the disposal or reuse of the distillers grains.

Locating a sufficiently large CAFO next to an ethanol plant would eliminate several disadvantages and inefficiencies associated with ethanol production, but this concept has not been successfully implemented because of environmental and land constraints which prevent such very large CAFOs from being built in the proper locations.
