About MADEP S.A.

MADEP SA: Microbiologie Appliqué: Déchets, Environnement, Polluants

MADEP SA has internationally recognized success and know-how in the field of isolation and cultivation of new bacteria and fungi for pollution degradation and site remediation without generation of new pollutants.
We offer these unique services to satisfy the specific needs of each client.
An innovative vision

Microbial biotechnology offers innovative scientific applications of great ecological and economic interest. It exploits natural degradation processes thereby eliminating environmental pollution at a significantly lower cost than physical/chemical and mechanical treatment techniques (excavation, confinement, incineration, land-filling).

MADEP SA's bioprocesses permit or accelerate the natural material and elemental dégradation cycles.

Realistic objectives

Since its birth in 2002, the pricipal objective of MADEP SA has been the development of the new biotechnologies. MADEP SA constantly searches for reliable, leading edge and proven ecological solutions that yield positive and guaranteed results.

Solid competence and quality infrastructure

Dr. Trello Beffa created MADEP SA following 10 years of research experience at the Changins agricultural research station and the University of Geneva and 10 years as the head of the Biowaste/Biodegradation group at the University of Neuchâtel. With nationally and internationally recognized know-how, a serious infrastructure, MADEP SA offers its clients high quality, customized services according to their specific needs.

Innovative high-performance products and services

MADEP SA offers a wide range of systems or bioprocesses, analysis, consulting services and products to effectively and economically solve all kinds of problems related to the clean-up of polluted sites and biological treatment of organic pollution and wastewater. MADEP SA distinguishes itself from competitors by its use of the Terrafors bioreactors developed with CTI funding from the Swiss federal government in collaboration with INFORS-HT AG (CH-4103 Bottmingen) and the University of Neuchâtel. These bioreactors enable MADEP SA to work in specific and controled environmental conditions that facilitate the selection of appropriate microorganisms and application conditions for treating solid and semi-solid organic wastes. Consequently, MADEP s.a. offers its clients effective, controlled and guarateed microbiologically based pollution control solutions developed in less time and at a lower cost than the established techniques.

Incontestable results

With its bioprocesses, bacteria, fungi and enzymes, MADEP SA is totally committed to biotechnology for the benifit of the environment. MADEP SA's technologies are a radical departure from current treatment techniques and remove pollution without generating additional pollution or harmful by-products. MADEP SA exploits nature to develop easily applied processes that yield a result that is more than satisfying.

Don't hesitate to asked for project references.

Let's work together for ecological and optimal solutions that meet our environmental objectives

Notes About MADEP SA's Bioproducts and Production Techniques:

The biotechnologies developed by MADEP SA use 100% natural microorganisms as defined by the European Federation of Technology standards AFNORx42-040- and the European Biochemistry Federation (class 1 E.F.B.). They are not genetically manipulated and are non-toxic for man, animals, plants and the environment.

All strains were discovered and cultivated by MADEP SA. MADEP SA holds all intellectual property rights related to these strains.

The formulation (type and number of microbial species) of the mixtures of bacteria or fungi is adapted according the substance to be treated, the type of existing infrastructure, the technical management employed at the treatment site, as well as the physical-chemical environmental conditions.
