The Biodegradability of Plastic Products for Agricultural Application: European Regulations and Technical Criteria

Clean Technologies, Journal Year: 2025, Volume and Issue: 7(1), P. 11 - 11

Published: Feb. 2, 2025

Plastic products are used in agriculture to increase crop yield and improve quality face a double challenge: growing world population depletion scarcity of natural resources. In this framework, the European Commission is working on establishing biodegradation criteria under conditions for certain plastic products. Such particularly important where key once reaching end their shelf life, considering an end-of-life scenario waste management either unfeasible or highly complex. Under scope, work aims provide comprehensive assessment current status regulations terms plasticulture product biodegradability, highlighting specific tests standards regarding biodegradability assessment. Biodegradation soil water has been considered criteria, threshold at least 90% organic carbon converted into CO2. These have followed tool-based study mathematical prediction model main existing families biodegradable polymers soil. will help fertilizer industry develop new formulations that more sustainable effective field.

Disintegration of commercial biodegradable plastic products under simulated industrial composting conditions

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 12, 2025

Biodegradable plastics are often promoted as sustainable alternatives to conventional plastics. Nevertheless, significant knowledge gaps exist regarding their degradation under relevant conditions, particularly when compounded into commercial products. To this end, the present research investigates disintegration of ten commercially available biodegradable plastic products simulated industrial composting conditions. The tested included polymer compositions either polylactic acid (PLA), polybutylene adipate terephthalate (PBAT)/starch, or polyhydroxyalkanoate (PHA), covering both flexible and rigid These comprised three waste bags, one bag drawstring, food (flexible plastics), two flower pots, container, plate, lid (rigid plastics). Among products, nine were marketed compostable. Of these, six certified European standard EN 13432 for compostable packaging, held TÜV Austria's "OK compost home" certification, was labeled but lacked certification. Additionally, product 100% environment in which could biodegrade not specified. Disintegration determined according ISO 20200 laboratory scale tests conducted at 58 °C with 55% moisture content over 90 days. Results showed degrees ranging from 75 100%, five achieving complete disintegration. Two however, reached only 75% Following test, particles smaller than 2 mm examined microplastics (MPs) via light microscopy. MPs detected undersieves while no Notably, visual inspection performed without pretreating matrix due observed using chemicals oxidative digestion. Considering limitations MP observation pretreatment, future should prioritize development methods extracting complex matrices like compost.

Challenges and opportunities in managing biodegradable plastic waste: A review

Waste Management & Research The Journal for a Sustainable Circular Economy, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 30, 2024

Biodegradable plastics have certain challenges in a waste management perspective. The existing literature reviews fail to provide consolidated overview of different process steps biodegradable plastic and discuss the support provided by legislation for same. present review provides holistic these comprehensive relative summary 13 European Union (EU) laws related circular economy, national legislations plus source separation guidelines countries, ensure optimal use resources future. Following were major findings: (i) numerous types low volumes pose challenge developing cost-effective infrastructure; (ii) are promoted as food-waste collection aids, but consumers often confused about their proper disposal prone greenwashing from manufacturers; (iii) industry-level studies demonstrating mechanical recycling on full scale unavailable; (iv) EU dealt with general topics plastics; however, only new proposal packaging policy framework bioplastics clearly mentioned (v) clear disparities observed between methods suggested available guidelines. Thus, appropriately manage waste, it is necessary develop processing material utilization infrastructure well create consumer awareness.
