Solid waste management is one of the most challenging issues for authorities in the Mt Everest region of Nepal, exacerbated in recent years by the rapid and continued growth of tourism. Open and unsightly landfills in the vicinity of villages along the main trekking routes are creating serious public health and environmental concerns, primarily because of their routine burning, resultant release of toxic chemicals, and contamination of groundwater supplies. Following 2 community consultations held in Namche Bazaar and Kathmandu in July 2019, a sustainable solid waste management plan was developed by the authors at the expressed request of local stakeholders. Based upon a collaborative approach, the plan proposes the implementation of a 4-point waste management process: (1) routine segregation of waste type at its source by lodges and home owners, (2) collection of recyclable waste from lodges and households and/or transfer of waste by lodges themselves to environmental stations, (3) transfer of all segregated waste to material recovery facilities for preprocessing and packaging, and (4) transfer of preprocessed materials to Lukla airport for transportation to Kathmandu and/or other recycling facilities. In January 2020, the plan was formally presented to local authorities, who, at the time of writing, are considering available options for its implementation. It is suggested that progress toward the sustainable management of solid waste in Khumbu be closely monitored in the coming years, as success here could provide working models for other heavily visited regions throughout the high mountain world.

尼泊尔萨加玛塔（珠穆朗玛峰）国家公园和缓冲区的可持续固体废物管理计划

对于尼泊尔的珠穆朗玛峰地区，固体废物管理是当局面临的最具挑战性的问题之一，近年来，旅游业的快速和持续增长使这一问题更加恶化。主要徒步路线沿线村庄附近的露天垃圾掩埋场引起了严重的公共卫生和环境关注，主要是因为它们的常规燃烧，有毒化学物质的释放以及地下水供应的污染。在2019年7月在Namche Bazaar和加德满都举行了两次社区磋商后，作者应当地利益相关者的明确要求制定了可持续的固体废物管理计划。该计划基于协作方法，提出了一项4点废物管理流程的实施方案：（1）旅馆和房主在其源头对废物类型进行例行隔离，（2）从旅馆和家庭收集可回收废物和/或由旅馆自己将废物转移到环境站，（3）将所有分类废物转移到材料回收设施进行预处理和包装，以及（4）将预处理后的物料转移到卢克拉机场，可运至加德满都和/或其他回收设施。该计划于2020年1月正式提交给地方当局，地方当局在撰写本报告时正在考虑实施该计划的可用方案。建议在今后几年中密切监测昆布省可持续处理固体废物的进展，因为这里的成功可以为整个高山世界其他人迹罕至的地区提供工作模式。
