'Paint waste', a part of the 'household hazardous waste', amounting to approximately 5 tonnes was collected from recycling stations in two Danish cities. Sorting and analyses of the waste showed paint waste comprised approximately 65% of the mass, paint-like waste (cleaners, fillers, etc.) comprised 15-25% and foreign items comprised 10-20%.Water-based paint was the dominant part of the paint waste. The chemical composition of the paint waste and the paint-like waste was characterized by an analysis of 27 substances in seven waste fractions. The content of critical substances was low and the paint waste was less contaminated with heavy metals than was the ordinary household waste. This may suggest that households no longer need to source-segregate their paint if the household waste is incinerated, since the presence of a small quantity of solvent-based paint will not be harmful when incinerated. Allowing household paint waste to be collected with ordinary household waste is expected to reduce the cost of handling household hazardous waste, since paint waste in Denmark comprises the major fraction of household hazardous waste.
“涂料废料”是“家庭危险废物”的一部分，从丹麦两个城市的回收站收集到约5吨此类废料。对这些废料进行分类和分析后发现，涂料废料约占总质量的65%，类似涂料的废料（清洁剂、填料等）占15 - 25%，外来物品占10 - 20%。水性涂料是涂料废料的主要部分。通过对七个废料组分中的27种物质进行分析，确定了涂料废料和类似涂料废料的化学成分。关键物质的含量较低，且涂料废料的重金属污染程度低于普通家庭垃圾。这可能表明，如果家庭垃圾进行焚烧处理，家庭无需再对涂料进行源头分类，因为少量溶剂基涂料在焚烧时不会造成危害。由于丹麦的涂料废料占家庭危险废物的大部分，允许家庭涂料废料与普通家庭垃圾一起收集有望降低处理家庭危险废物的成本。
