“…Developing countries produce a large volume of organic solid waste, including food, municipal, and agricultural wastes. The treatment of organic solid waste includes composting (Shan et al 2019), anaerobic digestion (Chen et al 2020), incineration (Lu et al, 2019), and the landfill (Cappucci et al 2020); amongst these, composting has reduced the financial burden of purchasing chemical fertilizers and can decrease the environmental impacts associated with the production of chemical fertilizers and their utilization. The application of compost products as organic fertilizers can reduce dependence on fertilizers and improve crop quality (Tubeileh and Stephenson 2020).…”

To achieve food security and increase crop productivity in a sustainable way, keeping soil fertile and balanced fertilization is vital. Soil fertility declining and unbalanced fertilization is one of the bottlenecks to sustainable agricultural production. To overcome these problems, a field experiment was investigated, with the aim of exploring the potential of organic and inorganic nutrient sources with their optimal application and integration for sustainable wheat production. The experiment was conducted in a factorial approach with three replications, where one factor was the level of the NP (Nitrogen and Phosphorus) fertilizer and the other compost, set in a randomized complete block design. Four levels of the N:P fertilizer (control, 27.6%:18.4%, 41.4%:32.2% and 55.2%:46%) were combined with three levels of compost (0, 3 ton/ha and 6 ton/ha), giving 12 treatments combination. From the data collected and analyzed, integrated application of the NP fertilizer and compost significantly increased soil organic carbon, total nitrogen, and available phosphorus but had no effect on soil pH and cation exchange capacity (CEC). Application of 6 ton/ha compost was higher with plant height, spike length, number of seeds per spike, 1000 seeds weight, and biological yield. The sole application of the NP (55.2%:46%) produced (6.19 ton/ha) grain yield whereas combined application of the NP (55.2%:46%) along with the compost (6 ton/ha) produced the higher grain yield (8.16 ton/ha). This clearly revealed that application of 75% recommended inorganic NP fertilizers combined with compost resulted in increased wheat yield by 27.45% over sole application of inorganic fertilizer indicated that the integrated approach could enable to save up to 25% of commercial fertilizers and increase the yield of wheat.

“…It should be noted that the same article can be in more than one category depending on the way the research was presented. The first category, by the number of articles published, was the one dealing with mechanical processes (37) with which to recycle, reuse, remanufacture, and reduce plastic waste at the end of the supply chain.…”

“…Articles related to mechanical processes discussed, among other topics: wet mechanical processing [30][31][32]; the identification and classification of waste in mechanical processes [33,34]; the recirculation of post-consumer and industrial bio-based plastic waste through mechanical recycling [4]; the technical-economic evaluation of the mechanical recycling of post-consumer plastic packaging waste [35][36][37]; and the analysis of material properties during and after the mechanical recycling process [38,39]. A relevant aspect in the analysis of the articles is that although we are developing other processes, mechanical processes are still, in many cases, the most adequate solution or complementary to other initiatives, such as in "Advancing Plastic Recycling by Wet-Mechanical Processing of Mixed Waste Fractions" by Schwabl, Bauer, and Lehner [30].…”

Management of Plastic Waste and a Circular Economy at the End of the Supply Chain: A Systematic Literature Review

et al. 2022

This article aims to describe the current state of research on plastic waste management as a circular economy practice at the end of the supply chain. The methodological strategy chosen was a systematic literature review. The articles selected from the Web of Science and Scopus databases were screened, and the research corpus consisted of 201 articles published in journals between 2014 and 2021. The results present 13 study categories, showing topics such as pyrolysis, business models, Industry 4.0, and energy generation. The insertion of Industry 4.0 technologies is still in its initial stages, comprising mainly the generation of inputs to reuse waste for 3D printers’ materials. Regarding energy generation, the insertion of processes such as pyrolysis for fuel generation stands out. The proposed discussion in this article suggests a circular ecosystem in which wastes follow a reuse flow according to their properties; incineration can be an option depending on the stage and benefits generated from the removal of plastic waste from the ecosystem. The highlighted issue is the scalability of the developed processes in the research, which is only possible if the state, universities, and civil society integrate efforts in the construction of a circular ecosystem infrastructure for waste management.

“…About 50% of plastics are intended to be used only once and are known as single-use plastics (SUPs). 1 Due to the non-biodegradability, most SUP waste such as packaging bags and water bottles are disposed of in landfills 2 or incinerated. 3 However, landfilling occupies a lot of land and space, while burning waste releases many pollutants that affect people living near these incinerators.…”
