Single-use plastic hygiene control products used during red meat processing can have severe negative impacts on the environment and cannot be processed with offal during rendering into meat and bone meal. However, plastics made from protein could potentially solve this problem as the material would be safe to render. The objective of this work was to prepare blends of blood meal and polybutylene adipate terephthalate (PBAT) in the absence of water using the interaction between PBAT and protein as the plasticisation mechanism. The ratio of protein to PBAT (1:1.3), as well as the choice of compatibiliser (PBAT-g-IA), was critical to form a homogenous, compatibilised blend with mechanical properties suitable for injection-moulded hygeine control products. This blend had a tensile strenght of 11.2 MPa, a chord modulus of 492 MPa, and 10% elongation at break. Using less PBAT in the blend, or using Surlyn™ as a compatibiliser, resulted in blends that were either too difficult to process or with inferior mechancial properies. Using simulated rendering, the new material was indistinguishable from tallow or meat and bone meal, suggesting that hygeine control products made from this new material will degrade sufficiently to be safe to render with offal after red meat processing. |
