In a market with a growing demand for renewable energies, Berkes aims to be at the forefront in the use of biomass as an energy source.

With 40 years' experience in the use of biomass, Berkes has accumulated know-how in the use of various types of organic fuels for the generation of steam and energy. We have an extensive portfolio of fuels with proven experience in their use, thus adding value to the by-products of industries and aligning them with company policies of environmental care.

In our continuous search for excellence and not settling for the developments already achieved, we are constantly researching and developing the burning of new biomasses, without failing to meet the highest levels of efficiency, emissions and reliability.


Sunflower seed husk is a by-product of the oil industry from the process of obtaining oil from the seeds, with the special feature that it contains a considerable amount of lignin which limits the possibility of rapid biodegradation.

However, its high energy value makes it attractive as a solid fuel. Therefore, it can be used as biomass for the generation of electrical energy or thermal energy for industry, reducing the impact of CO2 in the atmosphere and the dependence on fossil fuels.

At Berkes we have a proven and efficient solution for the use of sunflower seed husk as a biomass fuel.


Berkes has had experience in burning wood since the 80's, succeeding in using it as fuel in a wide range of formats and humidities.

Wood in rolls
Sawdust and sawmill cuttings
Wood chips
Wood waste
Pruning and forestry trimming

We have various technologies and solutions for most of the wood products and by-products on the market.

We combine them to offer a comprehensive project, covering the preparation of the wood from its reception to its burning, including transport, storage, drying, separation of particulates, and crushing, among other processes.

Organic sludge

Our "torsional chamber" combustion technology allows the burning of sludge from wastewater treatment.

Berkes offers comprehensive dewatering, drying and combustion solutions for various types of industrial sludge. They can enter the process with humidities of up to 85%.

Slaughterhouse Sludge
Paper sludge

We are constantly seeking to develop new fuels; we carry out operation experiments with previously unused sludge to assess the feasibility of energy projects.


To provide added value to malting plants and breweries, Berkes has developed the burning of:

Barley husks and dried malt
Spent brewery grain and malt directly from process (bran, pomace, bagasse)

In successful cases already developed, we have succeeded in taking the by-products directly from the process and introducing them into the steam plant as fuel; offering within the integrated solution the transport, drying (thermal and/or mechanical), crushing, reject separation, storage and injection into the boiler.


RDFs/SRFs are prepared from industrial waste by mechanical treatment, and from MSW by biological-mechanical treatment or mechanical-biological treatment. RDFs/SRFs can be used in cement plants, conventional thermal power stations, industrial plants, incineration in furnaces with energy recovery, gasification, pyrolysis and plasma.

Both can be recovered for use as fuel in incineration and co-incineration plants, as an alternative to landfill. The various advantages of their use as fuel include the following: reduced use of non-renewable energy, reduced greenhouse gas emissions, recovery of the energy contained in the waste and avoidance of landfill.

Other fuels

In addition to the most common biomasses, based on years of experience with various clients and the technologies of our strategic partners, we have the capacity to offer energy solutions using a wide range of industrial by-products that can be recovered for use as fuel.

  • Wheat Straw
  • Coffee Grounds
  • African Palm
  • Rice Husk
  • Corn By-products
  • Cane Bagasse
  • Leather
  • Tobacco By-products
  • Cardboard and Paper Recycling Waste
  • Coal
  • Cocoa Shells
  • Coconut Shells
  • Peanut Shells
  • Charcoal

Constantly striving to expand our portfolio, we seek development opportunities to innovate with new fuels.
