Phase 1: Origin of the residue

ComBio uses biomass of legal and environmentally sustainable origin. Any residue from agricultural activities and reforestation is considered as biomass. Much of the material we use has not been availed and, possibly, didn’t even have a proper final disposal.

Phase 2: Grinding and preparation

In some cases, the biomass needs to be processed. In our forestry unit located in the municipality of Capão Bonito, for example, we collect the crop residue of Eucalyptus and grind the material in such a way in order to enable an efficient logistics, in addition to adapt the product to the need of our boilers.

Phase 3: Logistics and Transportation

Logistics is one of the main costs of biomass production chain. The product, once it is very bulky and have a low added value, does not allow high costs in transport. For this reason, we use maximum cubage truckloads, thus minimizing logistics costs.

Phase 4: Biomass storage

Every ComBio’s steam unit has the structure for biomass storage. As the supply of material is just-in-time, this safety stock, which is enough for approximately five days, brings comfort when there is unforeseen events in the logistics of the material.

Phase 5: Steam Generation

In this step, the biomass comes to the furnace of the boiler through a power system. As of the burning, the hot gas resulting from this process heats the water. The steam generated then goes through a pipe to be delivered into the industrial line of the client, in accordance with the technical specifications predetermined in the Project.

Phase 6: Control and disposal of wastes

Completing our sustainable cycle, we use equipment that retain soot particles which could go into the atmosphere, making the gases released through the chimney invisible to the eyes. The CO2 emitted was absorbed by the biomass in its vegetative cycle, therefore, this is considered to be a “neutral balance of emissions”. The ashes are submitted to composting companies and for the production of organic fertilizers.
