Improving the sustainability and quality of DDGS, the high-protein animal feed co-product from bioethanol production, by using triticale as a biofuel feedstock

我们的目标是通过使用小黑麦作为生物燃料原料，提高用于动物饲料的高蛋白副产品，干酒糟和可溶性（DDGS）的可持续性。最近的研究表明，与小麦相比，小黑麦不仅具有良好的氨基酸结构，而且在氮肥需求减少、环境条件改善的高产土地上，小黑麦的表现也优于小麦。小黑麦以前从未被用作英国生物燃料原料，因此我们将：1)在不同的环境下展示小黑麦比小麦的成本和环境效益；2)在实验室对谷物、酒精和DDGS的质量进行评估；3)优化蛋白质输出；4)通过在商业工厂加工小黑麦来展示市场效用。该项目涉及整个供应链，包括育种商、农艺和研究公司以及生物燃料加工商。

We aim to improve the sustainability of the high-protein co-product used for animal-feed, Dried Distillers Grains with Solubles (DDGS), by using triticale as a biofuel feedstock. As well as having a favourable amino acid profile compared with wheat, recent research shows that triticale can out-perform wheat on high-yielding land with reduced nitrogen fertiliser requirements and improved environmental credentials. Triticale has never before been used as a UK biofuel feedstock, so we will:1) Demonstrate cost & environmental benefits of triticale over wheat across contrasting environments;2) Evaluate grain, alcohol & DDGS quality in the lab;3) Optimise protein output;4) Demonstrate market utility by processing triticale in a commercial plant.This project engages the whole supply chain including breeders, agronomy & research companies and a biofuel processor.
