Biomass generating center.

biomassForest biomass comes from logging activities and the need to carry out maintenance and cleaning of forests, and forest masses by means of cleaning, pruning, and clearing of forests, etc.
This waste stream also includes waste generated by the forestry industry (sawmills, first transformation industries, manufacturers of processed wood products, cork, and pulp manufacturers).

Project Objective.

The objective of the project has been to collaborate with a waste management company, in obtaining the license for the installation of a biomass generating center,  on rustic soil that responds to point 1. a) of the Annex of the NUR (Regional Urban Development Norms) of the Law of Territorial Planning and Urban Development of Cantabria.

Vegetable residues to be treated.

The plant is expected to treat different types of vegetal residues, in all cases,  they will be lignin-containing materials.

Clean waste.

  • Residues from the cleaning of forests.
  • Pruning residues
    • Municipal.
    • Agrarian.
  • Residues of the forest and timber industry (sawmills)
    • Fragments.
    • Slits.
    • Sawdust.
    • Crust.
  • Waste from packaging companies.

Waste improperly contaminated.

  • Construction waste.
    • Formwork, packaging…
  • Demolition waste.
    • Doors, window frames, beams, pillars…
  • Old furniture
    • Chairs, cupboards, shelves, boards.
  • Wood packaging.
    • Boxes, pallets, cages, drawers…
    • Pots, baskets, bases…
  • Reel.
  • Old or damaged Pallets.

The plant will not receive wood residues that have been treated with creosote, such as railway sleepers, or any other type of hazardous chemical.

Capacity of the biomass plant.

The plant is expected to start by treating between 800 and 1,000 tons of biomass waste per year from different sources. It is assumed that 5% of this amount will be improper (metal, glass, plastic …) that must be managed as waste, according to type and quantity generated. However, it is considered that the plant will progressively increase its treatment capacity up to 5,000 tons / year.

Biomass production process.

Vegetable residues will be inspected to minimize improper entry to the plant, and classified according to the origin and intended destination. They will be crushed to reduce them to particles of different sizes between 0.5 and 5 cm. Transferred through conveyor belts and motorized shovels to the boxes,  inside the container destined to the drying of the material. Drying will be done in the natural housing environment  at room temperature. Once dry, the material will be loaded on trucks that will transport it to the industries that will consume it as raw material or fuel.
