Our idea involves biodegradation of low density polyethylene (LDPE) and polyethylene terephthalate (PET) plastics at the household level. These are plastics which are difficult to reuse and recycle. In this project, kitchen and garden waste are mixed with soil and buttermilk, after which plastic subjected to heat pretreatment is added directly to the mixture. This set up is left to compost, so that the microbes present can degrade the embedded plastic effectively. Here, waste (plastic) is being eliminated using other waste (organic household substances) to give harmless by-products, which may even be used as organic fertilizer. On fine-tuning this approach, we may be able to clear up the landfills and waste dumps around us. Furthermore, wastes can be handled right where they are produced, without even a need for segregation into wet and dry groups. This method helps us degrade plastic using only household resources with no additional expenditure, and is a promising solution to the global problem of plastic waste management.
