                      Is a K-Tree planting that adapts to land conditions, soil
                      fertility, contours, soil acidity rainfall, fast growing
                      tree species suitable for planting in high densities, in
                      order to produce volume of biomass the largest with the
                      highest calorie yield in the shortest time. the wood
                      harvest is made of wood chips. Wood chips, which is needed
                      by the world pellet and pyrolysis industry. 
                      Along with the increase in the production of KOPRABUH
                      together members and bussines partner enter the downstream
                      industry which can absorb the entire timber production of
                      each plantation for the purpose of producing renewable
                      energy and providing competitive economic value for
                      KOPRABUH members.

                      It is a downstream industry from carbon sink, to make
                      renewable energy starting from Bio-Mass, wood pellets to
                      pyrolysis oil. which is purified into diesel oil, gasoline
                      and kerosine. The purification process produce heat,
                      Bio-Gas, Bio-Fuel and Bio-Char. Bio-Fuel enters the
                      market, Bio-Char is planted on plantations as a carbon
                      sink and Bio-Fertilizer, while Heat and Bio-Gas are used
                      by the ECO Industry.
