Our study investigates the use of biomass materials for enhancing the value of biodegradable plastic Flour, as an abundant raw material with low cost, has been applied in the field of degradable plastics, and blend films containing flour are potential materials in agriculture, medicine, and packaging industries To improve the mechanical properties of materials, blending flour with other polymers such as polymethyl cellulose and low-density polyethylene is regarded as the simplest way. Flour blended with synthetic polymer polyvinyl alcohol (PVA) has been studied as a potential biodegradable polymer Depending on the degree of biodegradability, it seems that PVA might provide a stable support medium for flour The mechanical properties and biodegradability of flour/PVA blended films have been reported by several researchers. However, their wide applications are limited by the lack of water resistance and the poor mechanical properties of flour/PVA blended films [8] Pineapple by-products consist of residual pulp, peels, stem, pomace, and crown. Increasing pineapple production leads to the generation of a foreseeable amount of pineapple waste. Increased production of pineapple-processed items generates enormous waste annually. Apart from these, rough handling of fruits and exposure to the adverse environment can destroy the fruits by up to 55% thereby generating waste. There is a great challenge of pineapple waste utilization leading to environmental pollution Efficient and eco-friendly utilization of pineapple waste is necessary for their value addition. Therefore, the biotechnological and robust approaches may be applied for the sustainable use of pineapple by-products due to the enormous availability of phytochemicals, antioxidants, biofuels, and phenolic compounds [9] Circular bio-economy approach through the integration of various process technologies for the utilization of pineapple waste into wide range of industrially importance compounds and products are necessitated thereby leading to better societal economics and a zero-waste scenario
