Wood Chips

Wood chips and other low-grade wood wastes are the major type of biomass fuel. Other common biomass fuel sources are agricultural. Wood-chips are cut according to the sizes ordered by the buyers and they are dishydrated through. Wood residues from pulp and paper manufacturing, lumber mills, and other industrial wood users are frequently used for producing biomass electricity. Hundreds of biomass fuel systems are currently at work in different parts heating schools, government complexes, and entire city downtowns, as well as producing renewable electricity.

Much of the raw materials Brazil Biomass Wood Chips SC we use for biomass from certified forests.

Brazil has tradition on biomass production and use. The country fulfils the main required conditions regarding large-scale production of biomass, such as land availability, adequate weather conditions, inexistency of particular constraints regarding labour and the domain both of biomass-production and biomass-conversion technologies in the agricultural and in the industrial sides. Brazil has tradition and a significant potential on biomass production. The historical importance of biomass energy in Brazil is due to a set of factors, including (i) the size of the country and the availability of land, (ii) the adequacy of its weather, (iii) the availability and the low cost of the working force and, most important, (iv) the domain of biomass-production and biomass-conversion technologies in the agricultural.

Technical and environmental aspects: 

i) Average annual yield: 25-50 t/ha for eucalyptus (7 years) and 20-40 t/ha for pines (12 years);

ii) Up to 3 harvests per planting for eucalyptus;

iii) Charcoal - increasing efficiency leading from 330 to 450 kg / t of wood (+ 36%), together with the achievement of 100 % from planted forests for 2010;

iv) No-tillage or reduced tillage is the usual method of planting;

v) Highly reduced input of chemicals;

vi) At licensing stage, it is required the adoption of general BMPs;

vii) Land availability for new forests may be met inside the 10 M ha already forested, even considering rotation practices.

Reasons: short-term rotation and increasing earnings obtained in productivity.
