Food waste originating in households in the Czech Republic is an important but unknown issue. Due to the country's membership among the most developed economies (European Union, OECD) and its commitments towards UN Sustainable Development Goals, the government must, inter alia, significantly reduce household food waste. However, reliable data and indicators based on internationally agreed approaches and methods have been missing so far. This article brings original results from a survey comprising over 400 Czech households based on the kitchen diaries method showing that, on average, surveyed households discarded 2.6 kg (1.1 kg per capita) weekly. After extrapolation, the total food waste was estimated to be 135.7 kg per household or 57.1 kg per capita annually. Half of the total food waste from surveyed households was thrown into municipal bins for mixed waste. Despite a relatively low total food waste stream, its disposal needs substantial improvement to meet national and international regulations as well as sustainability criteria.
源自捷克共和国家庭的食物浪费是一个重要但尚不明确的问题。由于该国属于最发达经济体（欧盟、经合组织）成员，并对联合国可持续发展目标做出了承诺，政府尤其必须大幅减少家庭食物浪费。然而，迄今为止，一直缺少基于国际商定方法和手段的可靠数据及指标。本文展示了一项基于厨房日记法对400多户捷克家庭进行调查得出的原始结果，结果表明，被调查家庭平均每周丢弃2.6千克（人均1.1千克）食物。经推断，估计每户每年的食物浪费总量为135.7千克，人均为57.1千克。被调查家庭产生的食物浪费总量中有一半被扔进了市政混合垃圾桶。尽管食物浪费总量相对较低，但对其处理方式仍需大幅改进，以符合国家和国际法规以及可持续性标准。
