“…However, when it comes to the disposal/waste management system, with very few exceptions [33,64], biopolymers cannot be chemically or mechanically recycled along with petrochemical plastics. For example, PLA can negatively impact the traditional recycling processes of PET [77,110].…”

“…The residues from the bioplastics' biodegradation are not generally toxic [54] and can be consumed by other living organisms [26]. However, some issues have been mentioned in recent literature [77,114] linked to the presence of fossil resins in the bioplastic items composition. The process of biodegradation depends on factors such as humidity, temperature, oxygen content, pH, time [23,29,43], nutrient availability [19,23], UV radiation [28,94], and microorganisms' presence [23,29,115].…”

“…Another volumetric method is reported in the ASTM D5526-94D norm that measures the percentage of conversion of organic carbon in the sample to carbon in gaseous form (CH 4 and CO 2 ) [127]. Similarly, the evaluation of the specific methane yield of the test material by biochemical methane potential (BMP) tests can be used as a method to evaluate the anaerobic biodegradability of bioplastics [77,127].…”

“…For this reason, erosion and perforation increase the speed of degradation because the holes formed accelerate the diffusion of oxygen and enzymes into the biopolymers [23]. Mass loss is strongly dependent on the temperature of the process as at mild temperature conditions (35-37 • C) the percentage of biodegradation is about 2-times lower than that at higher temperatures (over 55 • C) [77,111,132]. This effect is due to the efficient abiotic degradation at higher temperatures [77].…”

The problems linked to plastic wastes have led to the development of biodegradable plastics. More specifically, biodegradable bioplastics are the polymers that are mineralized into carbon dioxide, methane, water, inorganic compounds, or biomass through the enzymatic action of specific microorganisms. They could, therefore, be a suitable and environmentally friendly substitute to conventional petrochemical plastics. The physico-chemical structure of the biopolymers, the environmental conditions, as well as the microbial populations to which the bioplastics are exposed to are the most influential factors to biodegradation. This process can occur in both natural and industrial environments, in aerobic and anaerobic conditions, with the latter being the least researched. The examined aerobic environments include compost, soil, and some aquatic environments, whereas the anaerobic environments include anaerobic digestion plants and a few aquatic habitats. This review investigates both the extent and the biodegradation rates under different environments and explores the state-of-the-art knowledge of the environmental and biological factors involved in biodegradation. Moreover, the review demonstrates the need for more research on the long-term fate of bioplastics under natural and industrial (engineered) environments. However, bioplastics cannot be considered a panacea when dealing with the elimination of plastic pollution.

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.
