The project pursues the use of waste from the Cantabrian food sector (cereal waste from the spirits industry and whey), in order to manufacture an edible, biodegradable and compostable plastic substrate, as an alternative to current plastic production, providing a solution in favor of the recovery of industrial waste. For the development of the edible plastic substrate, arabinoxylan and kefiran compounds were used, from cereal residues and milk whey, respectively. Several formulations were developed to create a pre-industrial prototype of the biocomposite for the edible plastic substrate, likewise, a search was made on the use of whey to obtain biofilm.An exploitation plan was drawn up that evidenced the need to sell 1,900 kg of bioplastic pellets per month to ensure the economic viability of the process. This production would have a unit cost of €15/kg, lower than the estimated sale price of €20/kg. Although it is estimated that the business profit margin would not be very high, the positive environmental impacts are good enough to consider the implementation of the developed solution.
