“…Despite a wealth of study on composting, only few if any studies have attempted to determine toxicity of food waste compost. Mu et al [48] conducted a test on plant-growth in order to examine how nutrients in compost from food waste were able to grow vegetables and what the quality was for vegetables grown with this compost. However, they did not provide the phytotoxicity test of the compost.…”

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.

“…Rotating drum composting is a recent development of aerobic treatment processes, in which the substrates are managed within a closed vessel constructed in such a way as to ensure proper agitation and aeration and resulting in a uniform and consistent end product . Drum composting is a high rate system, which can be easily controlled through the management of different process parameters, allowing flexibility in retention times even in extreme climatologic conditions . The high rate process permits size reduction of the reactor while installation near the waste generation spots can be realized, thus significantly reducing the transportation cost and its environmental burden.…”

[20] The high rate process permits size reduction of the reactor while installation near the waste generation spots can be realized, thus significantly reducing the transportation cost and its environmental burden. Therefore, the rotating drum composter can be employed for decentralized composting in institutions, neighborhoods, commercial centers, and small communities.…”

The objective of this work is to investigate the composting of food waste in a continuous feed pilot scale reactor. Food waste, collected daily from university restaurants and canteens, are fed to the composting unit together with wood pellets. During the continuous process the maximum temperature reaches thermophilic levels. The carbon dioxide emission factor is 216 g C kg−1 total solids (TS) per day, while the average oxygen uptake rate is 1245 ± 957 g O2 kg−1 TS per day both based on the daily waste input. The average daily cumulative carbon closure is calculated as −12.5% (±35.2%) with ideal closure of 0%. Inoculation of the final product shows no formation of colonies for total coliforms, Escherichia coli, Enterococcus (E. faecalis, E. faecium, E. durans, and E. hirae) and Pseudomonas (P. aeruginosa). The average respiration activity (AT4) was 12.1 ± 2.14 mg O2 g−1 TS, indicating that the end product is not quite stable and some maturation time may be required, prior to its application as an organic fertilizer.

“…Composting is considered a good alternative for recycling organic solid waste because of its aerobic microbial conversion capacity of the biodegradable fraction of solid waste into an oxidized and harmless product; it also reduces greenhouse gas (GHG) emissions and eutrophication of natural water bodies 2 . In Colombia, composting is a viable and necessary option, since there are many places that are sources of contamination, there is no control of these and no treatment is applied.…”

The purpose of this research was to evaluate the production of compost, biol and biogas from organic solid waste using cattle manure as inoculum through aerobic and anaerobic biodigestion; two prototypes of biodigester were designed on a pilot scale. The monitored variables were pH and moisture in order to obtain good quality compost. Solid organic waste from a sample of restaurants in the city of Cartagena de Indias was used; cattle manure was also used for its production. The growth of mesophilic bacteria, fecal coliforms and fungi present in different stages of composting was monitored, using Brilla Broth and Mac Conkey and Brilla agar. The Most Probable Number method was used for counting microorganisms, and the successful collection of biological by-products and biogas was performed. The obtaining and quality of the compost from the experiments depended substantially on the use of inoculum, as evidenced by the aerobic/anaerobic experiments with inoculum, from which a greater quantity of by-products was obtained and complied with the optimum ranges for the chemical, physical and microbiological parameters for organic fertilizers.
