Wood chips are a type of biomass that can be used for fuel or as a substrate for growing mushrooms. They can be produced from many different types of trees, but the most common type used is hardwood. Wood chips can be sold to power plants as fuel, or to mushroom growers as a substrate. They can also be used on-site for landscaping purposes.
To find a market for wood chips, the best place to start is online. There are many websites that list biomass suppliers and buyers in your area. You can also contact your local power plant or mushroom grower to see if they are interested in purchasing wood chips.
