From Basic Engineering to Full Turnkey Projects for the agro industrial sectors of Sugar, Vegetable Oils, Biofuels, Agrochemical and Biomass

Sectors of Activities

Edible Oils and Fats
& Bio-Diesel


Oilseeds Extraction Plants, Edible Oils Refineries, Biodiesel Plants

DSEC's understanding of Vegetable Oils production and processing techniques provides a unique background for the implementation of a comprehensive project, being with its definition, its construction or its operation. As a natural extension of the Edible Oil activity, the production of Renewable Fuels such as Biodiesel is also part of DSEC's activities.


Sugar, Bio-Ethanol
& Biochemicals


Sugar Plants, Sugar Refineries,Bioethanol Plants, Biochemical Production Plants

The projected increase in world sugar demand of 90 million tons from 2010 to 2030 makes DSEC's know-how in the Sugar sector extremely valuable for the market. DSEC's expertise has been transferred successfully to the Oligofructose and Biochemicals sectors where its capabilities ranges from feedstock handling and processing up to final product conditioning. DSEC also identified Bioethanol projects as a logical application of its skills.


to Energy


Biomass to Energy Facilities
Electricity Cogeneration

Biomass is one of the most promising Renewable Energy sources on earth even though its usage is, often limited by logistical issues. DSEC is therefore concentrating its efforts on offering comprehensive solutions for those biomasses that are by-products from the processing of higher value feedstock and that are thus available in large quantities in an industrial complex.
