“…TS content in ASF was logically smaller at L/S of 10 as compared to L/S of 5 (Table 2). It can be noted that TS contents obtained here in the aqueous fraction (from 5 to 9.3 %, Table 2) were lower than reported in similar studies done on urban biowaste by other authors where TS contents as high as 18 to 31% were reported (Jank et al 2015;do Carmo Precci Lopes et al 2019;Micolucci et al 2015b). This parameter however is strongly modified by the experimental conditions, which vary from one study to another.…”

“…Sorting operations are used to remove undesirable materials or, on the contrary, recover valuable constituents from a waste flow (Ariunbaatar et al 2014;Pognani et al 2012). Several authors have used mechanical operations as pretreatments prior to anaerobic digestion (Hansen et al 2007;Do Carmo Precci Lopes et al 2019).…”

“…Press-separation was investigated to remove undesirable impurities and recalcitrant particulate matter from BW (Jank et al 2015) or to produce a biodegradable aqueous slurry (Micolucci et al 2015a;Do Carmo Precci Lopes et al 2019). However, most of published studies on the subject have concerned household BW mixed or not with green waste.…”

“…However, most of published studies on the subject have concerned household BW mixed or not with green waste. Do Carmo Precci Lopes et al (2019) reported that the design and implementation of mechanical pretreatments was still a challenging step to convert BW into methane and/or compost. To our knowledge, no comparative study has been conducted on specific BW categories as reported in the present article.…”

“…Literature data indicate that the share of OFMSW varies on average from 30 to 40% [10][11][12]. A key factor that affects the possibility of further use of biowaste is its quality; in particular, the impurities in the material collected [13][14][15]. This factor is closely related to the efficiency of the OFMSW separate collection system.…”

The Circular Economy and Organic Fraction of Municipal Solid Waste Recycling Strategies

2020

Densely populated areas with large incoming populations have difficulty achieving high separate collection rates of municipal solid waste. The manuscript analyzes the link between biowaste collection and circular economy requirements as a fulfilment of the recycling rates and using biogas as a sustainable energy source. Three biowaste collection scenarios and three technical scenarios for its treatment are considered. The first scenario assumes only composting for biowaste treatment, the next includes also anaerobic digestion. In the years 2020–2050, the separate biowaste collection level will increase, depending on the scenario, from 26.9 kg/inh. up to 148.1kg/inh. By 2030, the quantity of biogas generated from biowaste can grow to almost 9 million m3/year, enabling the production of renewable energy at annual levels of almost 17 GWh and 69 TJ. Using the third scenario, the quantity of biogas generated grows more than twice (in 2035). If the capture rate of biowaste increases from 15% to 20% and then to 25%, the quantity of biogas generated grows by, respectively, 65% and more than 100%. Unfortunately, none of the scenarios enables the required municipal solid waste recycling rates in 2030 (60%) and 2035 (65%), which demonstrates the significant need to develop more effective separate collection systems, including biowaste. Methodology applied in the paper can be used for other cities and regions trying to meet circular economy demands.

Microplastics in composts, digestates, and food wastes: A review

et al. 2023

View full text Add to dashboard Cite

Diverting food waste from landfills to composting or anaerobic digestion can reduce greenhouse gas emissions, enable the recovery of energy in usable forms, and create nutrient-rich soil amendments. However, many food waste streams are mixed with plastic packaging, raising concerns that food waste-derived composts and digestates may inadvertently introduce microplastics into agricultural soils. Research on the occurrence of microplastics in food waste-derived soil amendments is in an early phase and the relative importance of this potential pathway of microplastics to agricultural soils needs further clarification. In this paper, we review what is known and what is not known about the abundance of microplastics in composts, digestates, and food wastes and their effects on agricultural soils. Additionally, we highlight future research needs and suggest ways to harmonize microplastic abundance and ecotoxicity studies with the design of related policies. This review is novel in that it focuses on quantitative measures of microplastics in composts, digestates, and food wastes and discusses limitations of existing methods and implications for policy.
