Proceeding from the goals of sustainable development of the United Nations and the
active introduction of the principles of the circular economy's concept, the possibility of using
the secondary raw and material resources in the production processes is relevant. At the UN
Environment Assembly in 2022 representatives of 175 countries approved a resolution and called
for a joint effort of states to reduce plastic pollution. Biodegradable plastics are a well-known
alternative to traditional plastics with a long natural decomposition period. Among biodegradable
materials, compostable materials are especially interesting due to the possibility of absolute
degradation to biomass, CO2 and water. The problem of obtaining compostable materials is
related to the possibility of using secondary material resources and achieving certain quality
parameters of the final product. In this research, the criteria and technological solutions for
obtaining compostable materials for single use are reviewed. The requirements to the raw plant
material and the final product were analyzed, various ways of obtaining such materials and raw
material processing methods were investigated. As a result of the work, the ratios of the mixture
components were selected, the particle sizes of the plant component were determined, the use of
a hot press machine was validated and the technological parameters for obtaining the finished
form of the material were determined. The obtained results of the study are planned to be used
for the development of production technology of compostable bio-composites and its further
scaling for their mass production of bio-composite materials for consumer and industrial needs.
