Raw Material Procurement：
While most biodegradable materials on the market are derived from staple crops, Sincdoo is dedicated to selecting higher-quality, more responsible raw materials for PLA. We prioritize the procurement of raw materials that have minimal impact on food supply, such as straw, sugarcane, and a small amount of genetically modified corn, which are used for fermentation to produce PLA. These materials are often agricultural by-products or high-yield crops that do not significantly affect global food supplies. Additionally, the by-products of fermentation can be used for the production of other products.
This raw material procurement strategy not only reduces competition for food resources but also adheres to sustainable development principles, promoting environmental protection and resource efficiency. Sincdoo hopes to contribute to global food security and ecological balance while promoting PLA products.

Technological Innovation and R&D Capabilities：
PLA modified Granular Products: We collaborate with internationally renowned PLA resin companies, such as NatureWorks, Total Energies, Haizheng Bio, and Fengyuan, to customize modified PLA raw materials for different applications based on specific product characteristics.

The Sustainable Lifecycle of Polylactic Acid (PLA)

Polylactic Acid (PLA) is a groundbreaking sustainable material that demonstrates a complete circular lifecycle. Derived from renewable resources such as straw, corn starch, and sugarcane, PLA is processed into versatile products that, after use, naturally degrade through composting into organic fertilizer, water, and carbon dioxide. This eco-friendly cycle reduces waste, protects the environment, and contributes to a greener and more sustainable future.

Common Questions About Polylactic Acid (PLA)

Why is PLA considered environmentally friendly?

PLA is deemed environmentally friendly because it is derived from renewable resources like corn starch or sugarcane, which absorb CO2 during their growth, reducing greenhouse gas emissions. Moreover, PLA can fully biodegrade under proper conditions, diminishing long-term environmental pollution.

If PLA is inadvertently discarded in the environment, what is its impact on health and the environment?

Compared to traditional plastics, PLA, due to its biodegradable nature, will not persist in the environment and generate microplastics, thereby lowering potential harm to both the environment and human health.

How is PLA's biodegradability achieved?

PLA's biodegradability is achieved through the breaking of specific molecular chains under the high temperature and humidity conditions of industrial composting environments, eventually decomposing into carbon dioxide and water. This requires specific composting facilities.

What are the advantages of PLA in applications?

PLA's application advantages lie in its versatility and customizability. It can be used to manufacture packaging materials, disposable tableware, clothing products, durable goods, biomedical products, and even automotive interior products. It can also be modified by adding different additives to enhance its heat resistance or alter its biodegradation rate, meeting the needs of various fields.

How is PLA different from other bioplastics?

Compared to other bioplastics, PLA typically shows better performance in biodegradability, source material, and the environmental impact of its production process. PLA's raw materials are primarily agricultural crops, giving it a clear advantage in reducing dependence on fossil fuels.

Compared to traditional plastics, what are the safety and health advantages of using Polylactic Acid (PLA) products?

PLA products offer several significant advantages in terms of safety and health, especially when used for food packaging and containers and infant products:

1- No Harmful Substance Release: Made from natural renewable resources, PLA does not contain harmful Bisphenol A (BPA) or other chemicals that could negatively impact human health. In contrast, some traditional plastics may release harmful substances when in contact with food or exposed to heat.
2- Biocompatibility: Due to its bio-based nature, PLA is more body-friendly and widely used in the medical field, such as biodegradable sutures and drug delivery systems, indicating PLA is considered to have a lower toxicity risk to humans.
3- Reduced Chronic Exposure Risk**: Since PLA is biodegradable, using it reduces the accumulation of microplastics in the environment, thereby lessening people's indirect exposure to microplastics through the food chain. Long-term exposure to microplastics is believed to potentially have adverse health effects. Especially in baby toys, due to babies' chewing habits, it can prevent babies from ingesting plastics and causing harm to the body.
4- Safer Waste Disposal**: The biodegradable nature of PLA products means they can fully decompose under appropriate treatment conditions, reducing the risk of harmful chemicals being released into the environment during waste disposal processes.

The recycling of Polylactic Acid (PLA)

  1. Industrial Composting: PLA is biodegradable but requires specific industrial composting facilities with high temperatures and appropriate humidity levels for effective decomposition. This method can completely break down PLA into water and carbon dioxide.
  2. Chemical Recycling: Through chemical recycling processes, PLA can be depolymerized into its original monomers or other useful chemicals, which can then be reused in new polymerization reactions to create new PLA products.
  3. Mechanical Recycling: Although not as common as with traditional plastics like PET, mechanical recycling can also be applied to PLA. This involves physically grinding PLA products into small particles, then cleaning, melting, and reprocessing them into new products.
  4. Energy Recovery: Since PLA is made from organic materials, it can be incinerated to recover energy. While not the most environmentally friendly method of recycling, it can convert PLA into energy rather than landfilling in the absence of other recycling options.
