Biogas-Booster from Sugar Refining Waste Stream

厌氧消化是一种将有机废物转化为沼气的可持续技术。厌氧消化器通常在农场和食品加工业中使用。典型地，厌氧消化器使用将季节性变化的原料转化成甲烷和二氧化碳的细菌的聚生体。根据原料的组成和操作条件，气体输出可能会有所不同。如果不需要的材料进入反应器，则会发生消化器的部分或全部中毒。该项目旨在开发一种“沼气助推器”，能够增加或恢复连续消化器的气体产量，特别是在运行中断后。该项目的商业伙伴经营制糖厂，其工厂的一些支流经济价值很低。虽然可能不符合人类消费的指导方针，但这些糖流将为厌氧消化器中的微生物种群提供优良且易于获得的原料。将测试各种地层提高天然气产量的能力，同时监测微生物种群，以避免由于选择糖降解剂而造成微生物多样性的损失。该项目将产生一个原型沼气助推器，将在Edgardion的消化池进行测试，以及其使用指南，而不会对消化池的长期性能产生负面影响。

Anaerobic digestion is a sustainable technology to convert organic waste into bio gas. Anaerobic digesters are commonly found on farms and co-located with the food-processing industry. Typically anaerobic digesters use a consortium of bacteria converting a seasonally varying feedstock into methane and carbon dioxide. Depending on the composition of the feedstock and operating conditions the gas output might vary. Partial of full poisoning of a digester can occur if unwanted materials enter the reactor. This project aims to develop a 'biogas booster' with the ability to increase or revive gas production in continuous digesters particularly after operating disruptions. The commercial partner in the project operates sugar refining plants and some of the side-streams of their plants have low economic value. Though potentially not meeting guidelines for human consumption, these sugar streams will provide an excellent and easily accessible feedstock for the microbial population in an anaerobic digester. Various formations will be tested for their ability to enhance gas production while the microbial population will be monitored to avoid the loss of microbial diversity due to the selection for sugar degraders. The project will result in a prototype biogas booster that will be tested at Ingredion's digester, as well as guidelines for its usage without negatively impacting the long-term digester performance.
