BIOMASS
mission and vision
To facilitate the commercial relations between the consumer
"between the consumers of biomass fuels“ (any natural product suitable
for the production of renewable energy) and those producers whose surplus
of production, by-product or waste can be used for that purpose.
We believe on the potential of Spain, and specially of Andalusia
with its vibrant agricultural sector, to serve the growing demand
of biomass fuels and we want to facilitate and encourage its use,
increasing the level of renewable energy production and reducing
the environmental impact.
what we do
In SGTRES we serve large consumers of biomass, like cogeneration and trigeneration thermal power plants, industrial plants, etc..., by offering them the biomass products and services from the suppliers in our portfolio.
We have established preferential relationships with local and regional biomass providers, and we are continuously researching for new ones, thanks to our deep on-the-ground knowledge of the sector and to our privileged alliances, to ensure a portfolio of best-in-class suppliers.
our product
In SGTRES, we give preference to those biomass products that are obtained from the majority extensive crops in Andalusia, with special attention to the by-products of the olive, cotton and almond.
orujillo (olive bone)
The orujillo, or depleted olive pomace, is the by-product of the process of drying and extracting oil from the olive pomace or olive-cake.
Part of the orujillo generated in the extractors is self-consumed in the facility for drying the pomace. The rest is mainly used for the generation of electricity in biomass plants, generally in steam turbine technology plants located in the same complex of the extractor.
Its dry fraction is composed of skin (15-30%), bone (30-45%) and fine pulp solids (30-50%). It has a moisture content that varies between 9% and 12%, and a calorific value of 5.01 MW/MT on a dry-basis.
cotton plant
The remaining of cotton plants after the harvest of the bolls is one of the most abundant agricultural residues in Andalusia.
There is an important cultivation area in the region and it is relatively concentrated. Its elimination from the crop area implies a cost for the farmer, which favours the development of service companies.
Cotton is amongst the herbaceous crops with the highest surface energy density, with a calorific value of 4.69 MW/MT on a dry-basis, with an average moisture content of 10%.
almond shell
Spain is the third world producer of almonds, behind the US and Australia. Almond shells are the main by-product of this industry, representing 75% of the total amount of almond biomass volume.
Crushed, grinded and filtered, the almond shells have very similar characteristics to the wood pellet, with similar Low Calorific Value, but a lower specific weight, a very low ash residue (between 1,22% and 1.55%) and a moisture content of 8 to 12%, so it does not require drying. The calorific value on a dry-basis is 5.09 MW/MT.
hojín
The remains of thin leaves and branches, commonly called “hojín” material, are generated as a result of cleaning the olives before their processing in the mills.
Traditionally used traditionally for animal feeding, it is now mixed with other type of organic waste to produce compost. However, in most cases, it constitutes a residue from which its producer has to dispose of.
There is an increase in its use in biomass power generation plants, although it has a high moisture content, around 40%. The calorific value is 5.1 MW/MT on a dry-basis.
