Product Development with Biopolymers Made from Brewers’ Spent Grain (BSG) and Carboxymethylcellulose (CMC), Using 3D Food Printer

Abstract

The combined use of recycling, reuse and biopolymers from various sources can be contributing factors for the reduction on environmental impact raised from the production, use and disposal of plastics. The Brewers’ Spent Grain (BSG) is a by-product from beer production. In this context, the use of BSG to produce biomaterials can be an alternative for the destination of these residues from small and medium generators. So, the main aim of this work was to develop a product with a BSG and CMC developed and characterized material, using a 3D printer. The material was developed, and physical proprieties was determined, followed by a 3D print of prototypes. The main results already achieved show that the materials prepared with BSG and CMC have high mechanical resistance and water resistance is enough to use in disposable cups. Next, the 3D printer helps in the process of product development.
