Nowadays, wood, branches, leftovers from furniture factories, bamboo shavings, etc. can be said to be resources available throughout the country. Waste wood and wood affect the environment and pollute the air. How to turn these wood wastes into treasure? In some countries and regions, we often see large-scale wood pellet production line projects or wood pellet machine procurement plans. These wood pellet machinery can turn waste wood into biomass fuel pellets. So, what kind of wood can the wood pellet machine use to make pellets?
Wood Pellet Machine
Wood everywhere can be crushed and processed into sawdust, sawdust, shavings, and wood chips by a wood pellet machine. The processed raw materials can be made into biological pellets for burning, and some farmers use it as a gasket. In addition, the crushed wood chips can be used as organic fertilizer. Soft soil, etc. If you want to engage in such wood processing, you can first consider the local resources and your sales. If possible, investing in wood pellet machines is a good choice.
The raw materials produced by the wood pellet machine can be waste wood, branches, old furniture, etc. As long as it is wood products, both new and old can be used as raw materials to produce high-quality wood, which will not affect the quality of industry production in any form. So, which wood products can be processed into pellets, and are there specific classifications?
You will need to look carefully at your environmental permit and understand what you are allowed to burn. If it states waste wood, there should be a European Waste Catalogue (EWC) Code and description, it may also give a specific grade of the wood. So, as an example, the codes below mean you can only burn Grade A Waste Wood from EWC Codes. They work by splitting wastes into identifiable categories:
Table S2.2 Permitted waste types for use as fuel for in biomass boiler units
Waste code 19: Wastes from waste management facilities, off-site wastewater treatment plants and the preparation of water intended for human consumption and water for industrial use
Waste code 19.12: Wastes from the mechanical treatment of waste (for example sorting, crushing, compacting, pelletising) not otherwise specified
Waste code 19.12.07: Wood other than wood containing hazardous substances (19 12 06) from waste management facilities. Only visibly clean waste wood is permitted; no plywood, chipboard, and chemical treatments should have been applied and originating from streams segregated at the source (such as waste wood from pallets).
The above would not include waste wood that has come from a wood recycling facility, for example, where a large volume of waste wood fuel is produced. It is in fact very limiting to the operator to source fuel, therefore it is key that you check your permit and discuss your needs with your supplier!
Individual sites have different requirements for their fuels, which should be monitored and recorded to ensure you are only accepting onto site what you can legally burn.
For those permitted to combust waste wood, all suppliers have a Duty of Care to provide you with accurate European Waste Codes, descriptions and regular (monthly) laboratory fuel analysis reports for all deliveries of chips and pellets.
Wood grading and types
Here are a list of some of the most frequent biomass fuels, their grading, and descriptions:
Forestry Residues and Agro Pellets – EWC: 02.01.03 / 02.01.07: Pellets made from agricultural residues, food processing wastes, are also considered wastes unless the manufacturer has secured an ‘End-of-Waste’ declaration from the EA – if in doubt, ask your supplier!
