Abstract
A biodegradable composite includes an organic matter and a porous material, wherein the organic matter has viable bacteria, and a total plate count of the organic matter is greater than or equal to 104 CFU/g. The organic matter accounts for 40% to 80% of a weight of the biodegradable composite. The porous material accounts for 20% to 60% of the weight of the biodegradable composite. The biodegradable composite could instantly remove unpleasant odor and accelerate a decomposition process to form compost. A product containing the biodegradable composite is provided as well.
Claims4
A product adapted to contact a biological substrate, comprising:
- a biodegradable composite consisting of viable bacteria, a porous material, and water;
- and
- a biodegradable plastic that is decomposable by biological activities, covers and contacts with the biodegradable composite, wherein the biodegradable plastic comprises polylactic acid;
- wherein the product comprises less than or equal to 10% by weight of the biodegradable composite;
- wherein the viable bacteria accounts for 40% to 80% of a weight of the biodegradable composite, and a total plate count of the viable bacteria is greater than or equal to 104 CFU/g;
- wherein the porous material is selected from a group consisting of activated carbon, egg-shell powder, shell powder, bamboo charcoal powder and a combination thereof;
- and accounts for 20% to 60% of the weight of the biodegradable composite;
- wherein the viable bacteria is solid and a weight ratio of the viable bacteria to the porous material is 1:1;
- wherein the viable bacteria are selected from the group consisting of thermoduric bacteria, Bacillus thuringiensis, Pseudomonas putida, Actinobacteria, and a combination thereof;
- wherein the water accounts for 1% to 3% of the weight of the biodegradable composite.
