The global shift away from conventional plastics has ignited a green gold rush in the biodegradable and compostable bags sector. According to Grand View Research, the global biodegradable plastics market, of which bags are a significant segment, is expected to expand at a CAGR of over 15% from 2023 to 2030, reaching a staggering valuation in the tens of billions of USD [1]. This growth is not organic; it is primarily legislated. The European Union's Single-Use Plastics (SUP) Directive stands as the most influential piece of legislation, effectively banning a range of conventional plastic items and creating a massive, immediate demand for certified alternatives [5]. Similar, though less unified, regulatory frameworks are emerging across the United States (at the state level), Canada, and the UK, each with its own set of rules and approved standards.
For Southeast Asian (SEA) exporters, this presents a colossal opportunity. However, this opportunity is not an open field but a series of walled gardens, each with its own gatekeeper: certification. The two dominant international standards are EN 13432 (for industrial composting, required in the EU) and ASTM D6400 (its US counterpart). These are not simple labels; they are rigorous, costly, and time-consuming processes that test a material's ability to break down completely into water, carbon dioxide, and biomass within a specific timeframe under controlled industrial composting conditions. Crucially, these standards are not interchangeable. A product certified for the EU market is not automatically compliant for the US market, and vice versa. This fragmented regulatory landscape is the single biggest barrier to entry for many SEA manufacturers who may produce a genuinely biodegradable product but lack the resources or knowledge to navigate the certification maze [6].
