“…In order to valorize food waste, especially given that about 1/3 of total food production goes to waste [12], composting is indeed a valuable method of organic waste management [5]. Good waste management can also decrease the waste of resources [1], as food waste is regarded to be a renewable resource [8].…”

Abstract:As waste management is becoming all the more crucial, this study investigates the way in which house left-over organic waste can be better managed on site, in order to minimize the off-site treatment cost and maximize environmental performance. For the implementation of this research, a full year measurement was recorded, showing the organic leftover waste food intake of two rabbits in a household of four. The organic food, collected in two separate baskets suitable for composting-though one for rabbit intake-was 168.5 kg in total, plus 68.8 kg, which was delivered directly to the composting bin, along with food remains and rabbit feces. The results show that, over the examined year, a total of up to 0.417 metric tons of CO 2 equivalent per year emissions was avoided, suggesting that if 30 houses were to apply this methodology, one garbage truck journey per year would be saved. Overall, this study suggests that better information and environmental awareness can result in on-site, low cost, individual management of recyclable organic material, which would assist with the decrease in the cost of management, along with increased environmental performance.

“…(Figure 14) Composting of edible mushroom production wastes can be a technology of production of foods such as vegetables and organic manures at the same time; besides to manage the organic fraction of biomass in developing countries due to the simplicity and speed of implementation. This technology implies low costs in its application, compared to other processes, which require a strong investment for the installation, management, and operation of the necessary equipment [73]. Filter mud, cattle manure, ashes, lime and waste from cultivation of oyster mushrooms.…”

Worldwide, there is an increase in acreage dedicated to the competitive production of fruits, vegetables, flowers, and palms crops as productive diversification for food, feed, fiber, and fuels. However, in developing countries, there is malnutrition by an inadequate diet caused by deficiency in quality or quantity of food. Therefore, options are needed for the production of foods, mainly of high protein content such as edible mushroom from by-products. In Veracruz, Mexico, there is a large megadiversity of wastes derived from endemic plants, fruits, legumes, pods, leaves, straws, and flowers that are generated in a large amount and are disposed off through open-field burning without a specific use. The objective was to evaluate the potential of 30 nonconventional by-products and wastes for the production of low-cost oyster mushrooms Pleurotus ostreatus. Biological efficiency (BE) varied from 17.65 to 180% and at least the 60% of the evaluated substrates (BE greater than 50%) are viable for the production of mushroom Pleurotus especially in view of its low contamination in trials and abundance and availability and diversity throughout the agricultural year as wastes. Besides, the spent substrates were converted into organic manure compost, vermicompost and bocashi to close the cycle for new food production.

Purpose An experiment was conducted to evaluate the potential use of a combination of food waste compost with sorbents as immobilizing agents to aid the phytostabilization of Ni-contaminated soil, using Lolium perenne L. (L. perenne). Methods The content of Ni in plants, i.e. total and extracted by 0.01 M CaCl 2 , was determined using the spectrophotometry method. Tests for the phytotoxicity of food waste compost were carried out using Phytotoxkit ™ tests. Results The compost phytotoxicity tests showed that the growth of the roots of L. perenne was slightly stimulated for a compost concentration of 25%, showing the positive impact of this material on plant growth. The biomass of L. perenne in particular organs, Ni content and the properties of soil depended on the dose of a Ni contaminant and the type of mineral and organic mixture incorporated into the soil. Conclusions Ni accumulated predominantly in the roots of the L. perenne. The greatest increase pH was observed after compost with chalcedonite mixture was added to the soil. The application of mineral and organic mixture, containing compost from food wastes and chalcedonite as a soil amendment, tended to reduce the soil total and mobile fraction of Ni more in comparison to the un-amended soil. Graphical AbstractKeywords Aided phytostabilization · Nickel contaminated soil · Food waste compost · Sorbents Statement of noveltyProblems concerning food waste management and disposal worldwide are currently among the most difficult and most topical issues in the organized waste management system. Apart from the least appropriate placing of food waste in landfills, the methods for disposal/recycling of food waste are the production of animal feed and composting. It is considered that the compost may be recycled for the removal of heavy metals from contaminated soils through the use of organic acids, microorganisms and nutrients found in composts. In this manuscript, we show that the mixture of compost from food waste and mineral sorbents (chalcedonite, halloysite), are a promising amendments for co-remediation methods of nickel contaminated soils. These novel soil amendments could be used for enhanced phytostabilization methods.
