Abstract

The search for new sources of energy has intensified these days due to the environmental impacts caused by fossil fuels. The tripod composed of energy, food and water is the base of human existence. Food production implies the generation of organic waste and the need to manage it properly. The dairy and pig farming sectors have an essential role in the Brazilian economy, producing a large amount of waste. One energy and environmental alternative to treat this issue is anaerobic digestion. Here we aimed to optimize the production and composition of biogas obtained from cheese whey and swine manure. Batch-scale laboratory tests were performed on bench anaerobic digesters for 65 days with 6 triplicates loaded with different proportions of cheese whey and swine manure. The proportion of 50% cheese whey and 50% swine manure presented the highest biogas production and methane concentration (CH4).

以干酪乳清和猪粪为底物的厌氧沼气池沼气生产及组成优化
由于化石燃料对环境造成的影响,目前对新能源的探索已经加强。能量、食物和水组成的三脚架是人类生存的基础。粮食生产意味着产生有机废物,需要对其进行适当管理。乳制品和养猪业在巴西经济中发挥着重要作用,产生了大量的废物。解决这个问题的一个能源和环境替代方案是厌氧消化。在此,我们旨在优化奶酪乳清和猪粪产生的沼气的生产和组成。在台式厌氧沼气池上进行了批量实验室试验,6个3个重复,分别加载不同比例的奶酪乳清和猪粪,试验持续65天。奶酪乳清和猪粪比例分别为50%和50%时,产气量和甲烷浓度最高。
