It is expected that due to the new European Union regulation focus on waste management, managing kitchen waste will become more important in the future, especially in households. Therefore, it is crucial to develop user-friendly and odour-free containers to store kitchen waste. The study aimed to test the effectiveness of composts' biochar in reducing noxious odours and volatile organic compounds (VOCs) released during kitchen waste storage. Various amounts of compost biochar (0%, 1%, 5%, and 10%) were added to food waste samples and incubated for seven days at 20 °C. The released VOCs were analysed on days 1, 3, and 7 of the storage simulation process. The results indicated that adding 5-10% of composts' biochar to kitchen waste significantly reduced the emissions in 70% of the detected VOCs compounds. Furthermore, composts' biochar can be used to eliminate potential odour components and specific dangerous VOCs such as ethylbenzene, o-xylene, acetic acid, and naphthalene. A new composts' biochar with a unique composition was particularly effective in reducing VOCs and could be an excellent solution for eliminating odours in kitchen waste containers.
预计由于欧盟关于废物管理的新法规，未来管理厨余垃圾将变得更加重要，尤其是在家庭中。因此，开发便于使用且无异味的容器来储存厨余垃圾至关重要。该研究旨在测试堆肥生物炭在减少厨余垃圾储存期间释放的有害气味和挥发性有机化合物（VOCs）方面的有效性。将不同量的堆肥生物炭（0%、1%、5%和10%）添加到食物垃圾样本中，并在20°C下孵育7天。在储存模拟过程的第1天、第3天和第7天对释放的VOCs进行分析。结果表明，在厨余垃圾中添加5%-10%的堆肥生物炭可显著减少70%的已检测VOCs化合物的排放。此外，堆肥生物炭可用于消除潜在的气味成分以及特定的危险VOCs，如乙苯、邻二甲苯、乙酸和萘。一种具有独特成分的新型堆肥生物炭在减少VOCs方面特别有效，可能是消除厨余垃圾桶异味的极佳解决方案。
