摘　　要：木材碳化过程制造木炭的土窑效率低,是第三世界国家木炭废物增加的原因之一。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关联和方法在非洲并不广为人知。因为农户决定了能源使用的类型,所以提高社区农户参与再生木炭废物的生产和再利用能力,是维持环境可持续性的重要措施之一。本文介绍了坦桑尼亚基洛萨区的一种将木炭废物转化为家庭燃料能源和维持环境健康的方法。本研究的数据是通过对298个随机选择的家庭进行访谈、小组讨论和观察收集的,并采用SPSSStatistics 20进行数据分析。本研究中使用的木炭废物转化为燃料能源的方法表明,当地木炭废物制成可回收煤球,改善了树木采伐的行为,并通过再利用增加了附加燃料能源,减少了环境污染。因此,本研究为政策制定者采用木炭废物回收策略来解决与能源相关的问题奠定了基础,为坦桑尼亚及其他地区实现可持续发展和环境健康的目标提供了可能的方案。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.
