Our Story

The guiding principle behind RECOMILL’s inception has been to create an easy-to-buy and easy-to-deliver solution that will help protect our environment. In many economies, animal by-products and other by-products from the meat supply chain remain unexploited causing massive stress on nature. To solve the challenge, a modular animal by-product recycling mill has been developed.

Animal by-product rendering is only a small part of the circular economy chain or the meat supply chain. Other operators in the fields of energy generation, biogas production, waste water treatment and similar are also needed. RECOMILL, a fully owned subsidiary of WOIMA Finland Oy offers the proven “Honkajoki Concept” for the conversion of animal by-products into valuable commodities.

Honkajoki Oy has been producing and manufacturing pure raw materials from an animal origin since 1967. The company carries out research and development to reach ecologically sound production processes; top-notch recycling operations and improved methods of producing natural fertilisers, animal feeds and raw materials for the bioenergy industry.

The modular “Honkajoki Concept” employs the best available technologies (BAT) enabling end-customers to benefit from the decades of developoment and rendering experience. This development work is guided by the applicable legislation, research results in various fields and the recommendations of the European Fat Processors and Renderers Association (EFPRA).


WOIMA Finland Oy is a Finnish EPC supplier of modular waste-to-energy power plants and waste-to-value ecosystems. The plants use different waste and biomass streams to generate steam and electricity for the animal by-product rendering processes. We have over 20 years of experience working in energy-related projects in over 100 countries across the globe, especially in the developing world.



WOIMA’s modular power plants are the engine behind the RECOMILL Plant and RECOMILL Ecopark. Reliable power source has a major role in the circular economy using societies’ undesirable side streams, i.e. waste as fuel. The modular structure enables flexible power generation scheme as well as fast delivery and construction. The WOIMA and RECOMILL solutions can be in operation within 18 months.
