Our company

SINCE 1984

BIOTEC was established in Belgium in 1984 with the aim of developing appropriate conceptual, technological and methodological tools for tropical regions. The key objectives are to treat wastewater (agricultural, agro-industrial and urban) and manage solid organic waste. By doing so we add value to the by-products and use them as industrial, energy and agricultural inputs.

Mission - Vision


Our Vision (2050): Sustainable development of Humanity, fed through organic agriculture and powered with renewable energy


The sound management of the organic matter (carbon and nutrients) to generate renewable energy and to increase the fertility of soils.


  • Replace the usage of fossil fuels by the valorisation of agro-industrial organic by-products
  • Reduce the use of chemical fertilisers in agriculture, optimising the cycle of nutrients (return of the organic matter to the soil)
  • Generate gas and electricity from energy crops (grasses & forage)
  • Find creative solutions to prevent any discharge of effluents or waste to water bodies

Our people

BIOTEC has offices in several countries and a team of 6 nationalities. who speak 10 languages.

We are a human team characterised by its professionalism and commitment.

Creation of Biotec in Belgium

Biotec is set in Colombia

First bio-digester to treat the effluents of palm oil mills in Latin America (Colombia)

- Wave of bio-digesters (UASB reactors and other models) for paper industry, livestock and poultry slaughterhouses, coffee industry, sugar mills, yeast factories, rendering plants and urban wastewater.
- Composting plants for sugar cane filter mud cake, household waste, vegetable waste.

First Palm Oil Mill Effluent (POME) biodigester in the world in the form of a covered lagoon (Colombia)

First POME biodigester in the world registered as CDM (Clean Development Mechanism - tool of the Kyoto Protocol) (Honduras)

Establishment of Biotec International Asia (Malaysia)

First bio-digester for lemon juice effluent in the world (Argentina)

First system in the world of monitored liquid organic fertilisation in oil palm plantation (Honduras) - application by macro-drippers

First biodigester that combines POME and effluent from biodiesel plant (Colombia)

First large POME biodigester in Africa (Nigeria)

First POME biodigester in Brazil

2015 to 2019
Three biodigesters of 2 MW each on Bangka Island (Indonesia) - electricity for the Grid (Feed-In-Tariff).

2015 to 2019
R&D on “gas farms” using grass as feedstock + alliance with the SAUTER company in Germany (www.sauter-biogas.de) for the setup of AGROGAZ, a specific company for the generation of Renewable Natural Gas (RNG) from solid biomass in the Tropics

2015 to 2019
R&D on the “bio-drying” of cane distilleries vinasses as well as POME + alliance with the company SSP from India. Production of a nutrients-rich soluble powdered bio-fertilizer.

Corporate Social Responsibility

BIOTEC International sponsors the PRO-ORGANICA foundation for the development of social projects in Colombia

BIOTEC, consistent with its vision and mission, commits technical, human and financial resources in the pursuit of sustainability for the planet and humankind.

Pro-Organica has four fields of action:

  • Environmental education
  • Productive programs
  • R&D centres
  • Think Tanks

Research, Development and Innovation

Research, development and innovation has always been the strength of our evolution. We optimise and constantly renew our products and look for new solutions to the challenges presented to us.

Our department responds to external and internal requests using a diverse range of media, such as laboratory tests, industrial testing, collaboration with equipment suppliers, literature searches and feedback from our plants in operation.

The department has well-equipped research laboratory to carry out experiments in BMP (Bio methane Potential). These facilities also allow to assess the toxicity of a given compound, in addition of being able to assess the influence of particle size, temperature and other parameters.

Experiments to simulate continuos digesters for get real data applicable to the organic loads, yields, gas quality, nutrient deficiencies, etc.

Our R & D approaches:

  • Optimisation of existing systems
  • New feedstocks
  • New concepts

BIOTEC has been for 30 years a pioneer in its sector.

Major current developments (2018):
  • Bio-Drying of palm oil effluents:
  • As a result of a R&D with its technological partner from India, and subsequently to a similar development with cane vinasse, BIOTEC conceived POME bio-drying units (palm effluent), a combination of biodigesters, evaporators (MSE) and dryers (spray), to transform palm effluents into a bio-fertilizer powder with 50% organic matter and 30% of macro-nutrients.
