In a circular economy, the value of products and materials is maintained as much as possible; waste and resource use are kept to a minimum, and resources do not leave the economic flow once they reach the end of their life, but are reused and create further value. The paper presents the obtaining and characterization of a composite based on butadiene-co-acrylonitrile rubber - continuous phase, where are added post-consumer recycled wood particles, with dimensions of 500 nm - discontinuous phase, and ingredients, such as: active fillers, plasticizers, vulcanizing agents, antioxidants. Wood waste acts as a filling material which leads to the biodegradability of the composite and the decrease in density. The small size of the waste particles and their functionalization with potassium oleate leads to the formation of bonds between the matrix and the particles so that the physical-mechanical characteristics of the composite correspond to the requirements of the products obtained from it.
