Frequently Asked Questions
Are pulp-molded tableware items truly fully biodegradable? What conditions are required for biodegradation, and approximately how long does the degradation process take?
Pulp-molded tableware that meets national standards is 100% fully biodegradable. Its biodegradability must be certified by an authoritative body through a biodegradability test (such as GB/T 20197-2006, "Definition, Classification, Labeling, and Performance Requirements for Biodegradable Plastics"). Biodegradation requires certain conditions, with the key factors being an appropriate microbial environment, temperature, and humidity: under composting conditions (temperature of 55–60℃, humidity of 50%–60%, and abundant microorganisms), degradation occurs most rapidly; in natural soil environments, due to lower temperatures and reduced microbial activity, the degradation rate slows down; and if the material is placed in a dry, sealed environment, the degradation process will be significantly delayed. The duration of biodegradation varies depending on the environment: under composting conditions, complete biodegradation typically takes 1–3 months; in natural soil environments, it takes about 3–6 months; even in complex environments such as seawater, biodegradation can be completed within one year—far shorter than the hundreds of years required for conventional plastic tableware to degrade.
What are the core environmental advantages of pulp-molded tableware? How does it differ from traditional plastic tableware?
The core environmental advantages of these products lie in three key aspects: complete biodegradability, renewable raw materials, and zero environmental pollution. The raw materials predominantly consist of renewable non-wood fibers such as bamboo pulp, bagasse from sugarcane, wheat straw, or recycled materials like waste paper pulp—eliminating the need to deplete precious timber resources. After use, these products can fully degrade in natural environments (such as soil or composting conditions) into water, carbon dioxide, and organic matter, leaving no residual pollution like plastic microbeads. Compared with conventional plastic tableware, there are three main differences: First, in terms of environmental friendliness—plastic tableware is difficult to degrade and easily contributes to white pollution, whereas pulp-molded tableware is naturally biodegradable, aligning perfectly with the “dual-carbon” goals; second, in terms of raw material sources—plastics rely on petrochemical products, while pulp-molded tableware depends on renewable plant fibers; third, in terms of usage safety—pulp-molded tableware is produced without adding harmful additives such as fluorine-containing or plastic-containing substances, and it does not release toxic substances even when exposed to high temperatures. In contrast, some low-quality plastic tableware may release harmful substances like plasticizers.
