The main expected results are:

R1 Reduction of 35% of the total carbon footprint of the PHB-based packaging manufacturing processes (using whey), taking as a reference the PP-based packaging manufacturing ones.

R2 75% reduction of the BOD (biological oxygen demand) and 40% of the COD (chemical oxygen demand) of “industrialized” whey by-product (after its use for PHB production) when compared with original whey by-product without treatment.

R3 Eco-efficient viability of PHB bio-production processes from whey with productivity more than 20g of PHB/litre.

R4 Reduction of the production costs of PHB polymer up to 50% due to the use of by-products from dairy industries (revalorisation of whey surplus) instead of purpose-grown crops as raw materials.

R5 Obtaining a 100 % biodegradable packages (200 units) based on PHB polymer obtained by injection moulding processes (trays) with demonstrated application on dairy products (cheese).
