Pellets, Naturally



Wood pellets are organic fuel in small cylinder particles, produced by compacted biomass, generally from sawdust or wood waste. 

With a calorific value of 17 MJ / kg, equivalent to 5 kWh / kg, wood pellets have low humidity (below 10%) and ash (below 0.5%) content. These characteristics allow for very high combus-tion efficiency, of high energy value and almost clean combustion. On the other hand, its high density, higher than 650 Kg / m3, makes for easier storage and transportation. 

At present, exporting all of its production, Pinewells is among the companies within the Bioen-ergy sector. The company produces a type of bio fuel which, due to its characteristics, has no environmental impact, promoting reduction of CO2 emission. Furthermore, it promotes forest management by using products coming mainly from forest clean up and waste from the wood industry.

Types of Pellets: Domestic: Produced with 100% Pine and with a high energy value, domestic pellets are normally used in wood stoves, ovens, furnaces, boilers, barbecues and fireplaces appropriate for this type of biofuel. 

Industrial: Produced with a properly defined mix of several types, industrial pellets are commonly used in industry for the production of energy/heat
