Abstract
The disclosed invention describes a novel approach to the utilization of the fine mineral matter derived from coal and/or coal refuse (a by-product of coal refining) to convert a non-biodegradable plastic into a biodegradable plastic. The fine mineral matter could also be based on volcanic basalt, glacial rock dust deposits, iron potassium silicate and other sea shore mined deposits. The conversion of the non-biodegradable plastic into biodegradable plastic in soil further increases nutrients availability in soil with the transition metals released as a result of biodegradation of the biodegradable plastic.
Claims15
A biodegradable polyolefin composition comprising a product of:
- a non-biodegradable polyolefin-based product and
- an amount of carbon-free fine mineral matter derived from coal and/or mined from natural resources including volcanic basalt, glacial rock dust deposits, iron potassium silicate and/or sea shore deposits, with particle sizes ranging from less than about 50 μm to about 2 μm, forming a biodegradable polyolefin-based product.
