REA biodiesel production systems are designed to handle a variety of feedstocks, including waste from processors of animal protein such as meat packing and dairy production facilities. The modular design of the REA process allows the core biodiesel production system to be fitted with front-end modules for specific food-waste streams such as acidulation to process bone, degumming to process dairy fat, and decanting to separate high water content.

This modular design also enables system-level design approaches for regional processing facilities to efficiently convert widely disparate feedstocks such as brown grease, food processing waste, seed oils, and others. In cases where the economic return is not sufficient from processing a single waste stream, community efforts to harness multiple waste streams can lead to economies of scale to increase profitability for multiple stakeholders.

What separates REA biodiesel production technology from others is its capability to transform feedstocks high in free fatty acids into premium-grade biodiesel (ASTM B100). This capability provides a high-value solution for food-processing plants that are challenged with the disposal of byproduct and waste material.

Landfills have started to close off access to meat packers, for example, elevating the urgency for alternative solutions. By commissioning an REA biodiesel production system, food processors can not only mitigate disposal costs, but they can monetize their waste streams in a manner that makes solid economic sense.

While landfilling and incinerating have been standard disposal solutions for food processors, the need to lower environmental impact also presents an opportunity to shift to recycling practices that are sustainable.

The consumption of non-renewable energy is another area food processors can improve on. Biodiesel produced onsite from waste streams can displace - in whole or in part - existing energy sources.
