CLiP Solomon Islands Land Waste Audits and Interviews

This dataset contains 2 csv files. Solid_waste_audit_Solomon_Islands_Abundance.csv reports solid waste abundance and composition data from households and commercial activities expressed in number of items, weight or volume. Solid_waste_audit_Solomon_Islands_Metadata.csv reports the results of interviews done when solid waste samples were collected to gather metadata about household occupants social and behavioural metadata, including the fate of solid waste not collected through the official waste management service. Waste audits were conducted in eight communities between November and December 2018 in Guadalcanal (five villages along Lunga river, 81 samples) Malaita islands (Arabella, 37 samples; Kilusakwalo, 33 samples; Ambu, 26 samples). Commercial activities were also audited (31 in Honiara in Guadalcanal Island; and 16 in Auki, Malaita Island). A READ-ME text file contains the description of columns content for the two csv files. The Commonwealth Litter Project (CLiP) supported Solomon Islands to take action on plastics entering the oceans. Currently 80% of marine litter is estimates to be originated on land and Cefas contracted Asia Pacific Waste Consultants to assess the land waste production rates and waste management performances. The sample collection was limited by the ease of collection of samples, the ability to transport samples, as well as the presence and absence of collection systems Commercial premises were divided into four major categories. The methodology remained the same for both households and commercial premises. Domestic waste samples were collected household by household to determine the waste generation and disposal rate per household. In areas with house-to-house collection system, each household was approached, and its rubbish bags/bins ready for disposal were requested just before it was being picked up by the waste trucks. APWC did not undertake any sampling in Honiara from collection points. Interviews were carried out at the households or commercial premises where a sample had been taken the previous day. In areas with no collection system, each household was provided with a bag to use to dispose of their waste. Bags were retrieved after three days. Villagers were told not to dispose of any bulky waste or problem waste that they have been having trouble disposing of into the black bags. An interview was conducted with the member of the household depositing the bag. Interviews were conducted with all households where waste was collected. Most of the interviewing was undertaken in the evenings and early mornings or weekends. Local staff members were trained to undertake the interview. All waste was collected in labelled plastic bags that were individually opened to sort their contents into categories. Separated materials were weighed on a set of electronic scales. Beverage containers were stored and counted separately. Containers were sorted by size, material (e.g. plastic, aluminium) and product type (e.g. milk, juice). Further, all plastic bags were sorted into different types of bags and all containers were further sorted by size, material type and product type. Cigarette butts, coffee cups and takeaway containers were also segregated.Data quality was checked at several stages by Asia Pacific Waste Consultants before submission of the final version of the dataset. Data were checked during entering for completeness and adjust possible errors. Anomalies were also investigated.

本数据集包含2个CSV文件。其中，Solid_waste_audit_Solomon_Islands_Abundance.csv记录了来自家庭及商业活动的固体废物丰度与组成数据，数据以物品数量、重量或体积为计量单位。Solid_waste_audit_Solomon_Islands_Metadata.csv记录了采集固体废物样本时开展的访谈结果，用于收集住户居民的社会与行为元数据，包括未通过官方废物管理服务收集的固体废物去向。

本次废物审计于2018年11月至12月期间在8个社区开展，涉及瓜达尔卡纳尔岛（隆加河沿岸5个村庄，共81份样本）与马莱塔群岛（阿拉贝拉37份样本、基卢萨夸洛33份样本、安布26份样本）。同时对商业活动场所开展了审计：瓜达尔卡纳尔岛霍尼亚拉31处、马莱塔岛奥基16处。另有一份READ-ME文本文件，用于说明两个CSV文件的列内容含义。

英联邦垃圾项目（Commonwealth Litter Project, CLiP）为所罗门群岛提供了海洋塑料污染应对支持。当前据估算，80%的海洋垃圾源自陆地，英国海洋生态与水产科学中心（Cefas）委托亚太废物顾问公司（Asia Pacific Waste Consultants, APWC）评估陆地垃圾产生率及废物管理绩效。

样本采集受到样本获取便利性、样本运输能力以及收集系统存在与否的限制。商业场所被划分为四大类别，家庭与商业场所采用了一致的审计方法。

家庭废物样本逐户采集，以确定每户的废物产生量与处置率。在实行上门收集制度的区域，研究人员在垃圾车即将收运前，联系每户居民，请求查看其准备处置的垃圾袋或垃圾桶。APWC未在霍尼亚拉的垃圾收集点开展采样。

访谈于采集样本的前一日在受访家庭或商业场所开展。在无上门收集制度的区域，研究人员为每户居民提供专用垃圾袋用于处置垃圾，3日后回收该垃圾袋。同时告知村民不得将此前难以处置的大型垃圾或疑难垃圾装入黑色垃圾袋，随后与投放该垃圾袋的住户成员开展访谈。所有完成废物采样的家庭均接受了访谈。大部分访谈安排在晚间、清晨或周末开展，本地工作人员均接受了访谈实施的专业培训。

所有废物均装入带标签的塑料袋，随后逐一开箱将内容物分类。分拣后的物料使用电子秤称重。饮料容器单独存放并计数，按尺寸、材质（如塑料、铝制）及产品类型（如牛奶、果汁）进行分类。此外，所有塑料袋需按袋型细分，所有容器需进一步按尺寸、材质类型及产品类型归类，烟蒂、咖啡杯及外卖容器也需单独分拣。

在数据集最终版本提交前，亚太废物顾问公司已在多个阶段开展数据质量管控：录入数据时核查完整性并修正可能存在的错误，同时对异常值开展溯源调查。
