Plastic is one of the major menaces in our country, there has been many natural disasters registered for which plastic has been reasoned the major cause. It has been observed that plastic from food waste contributes to the majority of the Solid Waste. The current survey done at national level in India by the Food Safety and Standard Authority (FSSAI) stated that over 21% of sweet boxes, aluminium containers have 24%, 80% carry bags and black coloured bags are 59% have non-permissible amount of plastics in them. The plastic cutlery results in about 22,000 tons of waste per month. The packaging waste is always dumped in landfill followed by recycling, incineration and composting.There has been development of various bio compostable plastics from various sources such as starch, proteins, cellulose, lipid etc. The usage of activated charcoal has been an age-old antidote for removing toxins and other poisonings from human body. The corn starch which has high tensile strength in comparison to other starches makes it feasible to be used as replacer for aluminium containers and PET bottles. For the plastic characteristics glycerine has been used to act as a plasticizer for the making of biopolymer. The film was made using activated carbon charcoal from coconut shell wastes, corn starch and glycerine in different combinations using 0,1,2 as levels for combination of the raw materials respectively. The films were initially tested for rehydration property as well as for the desirable structure of the film. The films were then subjected to physical, mechanical properties and shelf life testing of food. Based on the results, 1:2:2 combinations was found to be the best sample and was moulded in the form of pouches to eliminate the direct contact food packaging which can be used for the alternative for bakery products as well as many other food packaging
