An optimised composting mixture from previous In tank composting studies (50% food waste, 40% manure, and 10% bulking agent) was evaluated using windrow composting. Conventional layering and mixing were used for constructing the windrows. Temperature was monitored as the indication of the efficiency of composting.
Oct 1, 2021 · The economic assessments for waste to value able products have been published, such as food waste to compost (Chen, 2016), slaughterhouse waste to biopolymer (Shahzad et al., 2017a), slaughterhouse waste to biodiesel (Shahzad et al., 2017b), organic waste to biogas (Al-Wahaibi et al., 2020), MSW to value-added products (Nizami et al., 2017).
Aug 1, 2005 · One beneficial way of using In tank systems is to determine composting properties of different organic wastes of interest and optimise the process before application on windrow composting. If accomplished, this leads to more economical intensive data collection for better management on windrow composting.
Jan 20, 2024 · Food waste (FW) is an important component of household waste that comprises 36–76% of domestic refuse; it is primarily generated by food service providers, cafeterias, and households. China’s FW production reached 127.75 million tons in 2020, and this was largely driven by rapid urbanization ( Wang et al., 2022a , Wang et al., 2022b ).
However, the light self-shading, excessive water supply, and insufficient space utilization in microalgae farming have limited its potential in the inland areas most in need of regenerative food solutions. Herein, this work develops a 3D polysaccharide-based hydrogel scaffold for vertically farming microalgae without needing liquid media.

We used a non-invasive micrometeorological mass balance approach optimized for three-dimensional commercial-scale windrow compost piles to measure methane (CH4), nitrous oxide (N2O), and carbon
Our findings showed that the initial moisture contents of 55–70% and the 20% w/w of mature compost were optimal for effective food waste composting. A 400 kg compost pile with the optimal compost mixture ratio was then used to study the evolution and spatial distribution of the temperature during a 30-day composting period.
