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.
Claims28
A method of converting a non-biodegradable plastic into a biodegradable plastic comprising:
- obtaining an amount of 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;
- and
- melt blending, dry blending, or compounding the fine mineral matter with the non-biodegradable plastic to convert the non-biodegradable plastic into the biodegradable plastic.
A method of converting a non-biodegradable plastic in soil into a biodegradable plastic comprising:
- obtaining an amount of 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;
- and
- melt blending, dry blending, or compounding the fine mineral matter with the soil comprising a non-biodegradable plastic to convert the non-biodegradable plastic into the biodegradable plastic.
A biodegradable polyolefin composition comprising:
- a non-biodegradable polyolefin-based product;
- and
- an amount of 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, wherein the fine mineral matter causes the non-biodegradable polyolefin-based product to become biodegradable.
A modified soil composition comprising:
- a non-biodegradable polyolefin;
- and
- an amount of fine mineral matter, wherein the fine mineral matter is 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, and wherein the fine mineral matter causes the non-biodegradable polyolefin to become biodegradable.
