摘要
据报道,在木材炭化过程中使用的土窑效率低,这是全球南方增加木炭废物的来源之一。然而,将木炭废物转化为有价值的能源和促进环境健康的潜在联系和方法在非洲并不为人所熟知。促进地方社区能力参与家庭一级再生木炭废物的生产和再利用,是维持环境服务的可持续性的重要措施之一,因为家庭可以决定所使用的能源类型。本文介绍了坦桑尼亚基洛萨区将木炭废物转化为燃料能源的方法,用于农村家庭和环境卫生。为了达到本研究的目的,本研究通过随机抽取298户家庭进行访谈、焦点小组讨论和观察等方式收集初步数据。采用IBM SPSS statistics version 20 Cross tab工具进行数据分析。结果表明,本研究中使用的将木炭废物转化为燃料能源的方法表明,从土窑到销售中心的不同阶段收集的当地可用的木炭污染物制成可回收的压块的能力,改善了树木的采伐行为,通过再利用增加了另一种燃料能源,最终减少了当地的污染。因此,这项研究为决策者采取木炭废物回收战略以解决与能源有关的问题并最终加强环境卫生,促进坦桑尼亚及其他地区的可持续发展提供了基础。
Charcoal Wastes-to-Fuel Energy Conversion for Circular Economy and Environmental Sustainability in the Global South: a Case of Wood Charcoal Industry in Tanzania
Low efficiency of earth kilns used in the carbonising process of wood to make charcoal has been reported as one of the sources of increasing charcoal wastes in the global south. However, the potential link and approaches of converting charcoal wastes-to-valuable energy and for the environmental health is not well known in Africa. Promoting local community capacity engagement in the production and reutilisation of recycled charcoal wastes at the households' level is one of important measures to maintain environmental services for sustainability since households make decisions on the type of energy used. This paper, presents an approach of converting charcoal wastes to fuel energy for rural households and environmental health in Kilosa District, Tanzania. To achieve the objective of this research, the primary data were collected through interviews held with 298 randomly selected households, Focus Group Discussions and observations. IBM SPSS statistics version 20 Cross tab tools were used in the data analysis. Results revealed that the conversion of charcoal wastes-to-fuel energy approach used in this research demonstrates the ability of recyclable briquettes made from the locally available charcoal pollutants collected at different stages from earth kilns, to selling centers, improves tree harvest behaviour, adds another fuel energy source through reutilisation, and ultimate reduces pollution at the local level. Thus, the study provides a basis for policymakers to adopt charcoal wastes recycling strategies to address matters related to energy and ultimately enhances environmental health for sustainable development in Tanzania and beyond.
