Standardization involves establishing accepted criteria and guidelines for the quality, safety and acceptability of products and evaluating industry claims (OECD, 2018e). Standards relevant to single-use plastics are generally associated with safety risks and environmental impacts; they relate for example to harmful substances, recycled content, biodegradability, compostability, recyclability and bio-based plastics. Product standardization reduces the likelihood of off specification single use plastics and allows for better management of a product once it becomes waste (OECD, 2018e). Product standards also help ensure fair competition, promote commercial growth by overcoming barriers that result from unclear or inconsistent specifications and communication and help prevent fraudulent market behaviour (European Bioplastics, 2016). They are an essential component of any robust single-use plastics regulatory framework. Source: UNEP/World Resources Institute (2021).
