Most of the food waste (FW) generated by commercial activities and the majority of household FW is collected as part of general waste, which is either incinerated or landfilled. There is an increasing interest in the collection of FW as a separate waste stream and use it for the production of compost or recovery of energy through anaerobic digestion (AD) or pyrolysis. This study focused on using FW to produce chicken feed and liquid fertiliser (CFLF). The food waste samples were collected from food related businesses such as service club, café, restaurant, bakery and supermarket. The CFLF process was used to produce chicken feed pellets containing 19% of protein content, which is within the range of 16 to 22% of most commercial chicken feed pellets and within the National Research Council (NRC) recommended range of 15 to 23%. The liquid extract derived from CFLF process had high nutrient concentrations similar to those present in the feed solution used in hydroponic systems. Hence, the liquid extract from CFLF can be used to replace the commercial liquid fertiliser used in hydroponic systems. Environmental impact analysis of CFLF process using GaBi life cycle analysis (LCA) software indicated that the CFLF process can yield environmental credits for 15 out of 19 categories of impacts considered in the analysis. The measured environmental credits were significantly higher than the other disposal options such as, anaerobic digestion (AD), incineration and landfill.

商业活动产生的大部分食物垃圾 (FW) 和大部分家庭 FW 都作为一般垃圾的一部分收集，这些垃圾要么焚化要么填埋。人们越来越关注将 FW 作为单独的废物流收集，并将其用于生产堆肥或通过厌氧消化 (AD) 或热解回收能量。本研究的重点是使用 FW 生产鸡饲料和液体肥料 (CFLF)。厨余样本收集自与食品相关的企业，例如服务俱乐部、咖啡馆、餐厅、面包店和超市。CFLF 工艺用于生产含有 19% 蛋白质含量的鸡饲料颗粒，在大多数商业鸡饲料颗粒的 16% 至 22% 的范围内，并且在国家研究委员会 (NRC) 推荐的 15% 至 23% 的范围内。来自 CFLF 过程的液体提取物具有高营养浓度，类似于水培系统中使用的进料溶液中存在的营养浓度。因此，CFLF 的液体提取物可用于替代水培系统中使用的商业液体肥料。使用 GaBi 生命周期分析 (LCA) 软件对 CFLF 过程的环境影响分析表明，CFLF 过程可以为分析中考虑的 19 类影响中的 15 类产生环境信用。测得的环境信用显着高于其他处置方案，如厌氧消化 (AD)、焚烧和垃圾填埋。CFLF 的液体提取物可用于替代水培系统中使用的商业液体肥料。使用 GaBi 生命周期分析 (LCA) 软件对 CFLF 过程的环境影响分析表明，CFLF 过程可以为分析中考虑的 19 类影响中的 15 类产生环境信用。测得的环境信用显着高于其他处置方案，如厌氧消化 (AD)、焚烧和垃圾填埋。CFLF 的液体提取物可用于替代水培系统中使用的商业液体肥料。使用 GaBi 生命周期分析 (LCA) 软件对 CFLF 过程的环境影响分析表明，CFLF 过程可以为分析中考虑的 19 类影响中的 15 类产生环境信用。测得的环境信用显着高于其他处置方案，如厌氧消化 (AD)、焚烧和垃圾填埋。
