Compostability of single serve beverage ingredient packages

GCUP技术公司(GTC)开发了一种可生物降解和可堆肥的单一服务并获得了专利 可用于例如Keurig®风格咖啡冲泡的类型的饮料配料包 机器。GTC希望通过测试来确定其产品的堆肥特性 “G-Kup”。通过与化学和生物公司的合作研究和开发活动 在UBC的工程学，GTC希望识别和了解可以在一个 以有效和及时的方式，以及相关的关键挑战。这项研究的主要目的 项目是确定GTC产品在不同堆肥参数下的生物降解性。这个 拟议的研究将开发完全分解各种可生物降解配方的方法。生物反应器 将被设置为模拟真实的堆肥环境，这与 堆肥业-充气静态堆肥(仅限充气)和容器内堆肥(充气加常规堆肥 激动人心)。样品的生物降解性将主要通过测量失重率来确定。在……里面 此外，还将测量相对分子质量的变化以及木质素和纤维素含量的变化 G-Kup组件。成品堆肥中不含有害物质将通过进行 种子发芽试验。

GCUP Technology Corp. (GTC) has developed and patented a biodegradable and compostable single serve beverage ingredient package of the type which may be used, for instance, in a Keurig® style coffee brewing machine. GTC would like assistance with tests to determine the compostability characteristics of their product "G-Kup". Through collaborative research and development activities with Chemical and Biological Engineering at UBC, GTC hopes to identify and understand the technologies that can degrade the G-Kups in an effective and timely manner, as well as the associated key challenges. The main objective of this research project is to determine the biodegradability of GTC's product within different composting parameters. The proposed research will develop ways to fully decompose the various biodegradable formulations. Bioreactors will be set up to mimic real composting environment pertinent to two techniques commonly adopted in the composting industry - aerated static pile (aeration only) and in-vessel composting (aeration plus regular agitation). Biodegradability of the samples will be determined primarily by measuring percent weight loss. In addition, changes in molecular weight, and changes in lignin and cellulose contents will be measured for the G-Kup components. The absence of harmful substances in the finished compost will be verified via conducting seed germination tests.
