Purines Almazán, S.L.

Almazán (Soria) – Spain

PURAL is a leading Spanish company in valorisation of organic waste from the farming and agro-food industry. For doing so, it integrates the most innovative and sustainable technologies, taking advantage of its wide experience in the industrial sector and in R&D area and boosting the synergies between processes and organic waste for a complete valorisation. Both, the experience acquired by PURAL in the last years on waste valorisation and its efforts in R&D, have allowed to PURAL to grow in this sector by developing new products and process with the aim to convert wastes in resources.

PURAL is strongly committed with environment. Our business activity is focused on minimizing the environmental impact of waste from farming and agro-food industries and to strengthen an energy self-sufficient integral process. Besides, PURAL has developed an innovative concept, unique in Europe, integrating anaerobic digestion and rendering processes in one industrial facility. In the first process, wastes are valorised to obtain biogas, used to produce electricity, and a digestate which is used as fertilizers. A part of the biogas is used in heating the adjacent rendering process for treating pig carcasses under EU and Spanish regulations. In this rendering process, Category 2 ABPs are treated, sterilized and recycled, producing a biomass which is currently used to obtain meal (proteins) and fats as end products. Fats are focused to biofuel markets and the meal is used in the anaerobic digestion plants to increase the biogas production.

LIFE byProtVal project is of PURAL great interest. It will allow us to find new markets for the rich protein waste (meal), such as the manufacture of chemicals such as bio-adhesives for wood industries, footwear products or bio-flocculants, emulsifiers or foaming agents.
