How Our Biodegradable Additives Works
Our additive aims to overcome the constraints associated with surface-level plastic degradation. This advancement empowers microbes to target and consume the C-C bonds within the plastic’s structure at a macromolecular level, resulting in an increased surface area for plastic products. As a consequence, plastophilic microbes readily attach to the newly formed cavities in the polymer, optimizing the degradation process.
Unlike conventional plastics that can persist in landfills for hundreds or even thousands of years, the biodegradable enhanced plastic takes a revolutionary approach. It becomes a magnet for over 600 diverse types of microbes, effectively inviting them to digest and consume the plastic. This breakthrough accelerates the biodegradation process, offering a sustainable alternative to the long-lasting environmental impact of traditional plastics.
Journey to Biodegradation
How does our biodegradable additive work to make plastic more eco-friendly?
Additives work in most polymer PE, PP,PS, PET, BOPP Flexible and Rigid
Additive makes polymer molecules more hydrophilic.
Treated plastic packaging gets used, reused and recycled as per original plastic until it gets disposed
Gases can be collected as in some countries to produce energy
NOT breakdown to little pieces
Differences of 3 main technologies in the market

Most Popular Questions
When a product containing SAWeco additive is discarded in an active microbial environment, it possesses the capability to attract over 600 distinct microbial varieties found in both aerobic and anaerobic settings. These microbes form a colony, create a biofilm around the product, and commence enzyme secretion. Upon contact with the SAWeco additive, these enzymes act as catalysts, aiding in the breakdown of complex polymer chains. This process facilitates the complete return of the product to nature, leaving only minimal biomass and water residues.
As the product undergoes rapid biodegradation, facilitated by the SAWeco Additive, the majority of the mass is emitted as gases. These gases now hold the potential to be transformed into natural and renewable energy sources.
No, a microplastic is defined as a plastic particle smaller than 5 mm that lacks biodegradability.
When items treated with the SAWeco additive undergo biodegradation, the majority of the product's mass is released as gases, leaving behind minimal biomass and water. The entire product returns to nature. Importantly, the SAWeco additive does not play a role in the creation of microplastics.
Microplastics are generated when products containing technologies like oxo-degradable technologies use heat, light, and mechanical stress to fragment plastic in an abiotic (physical rather than biological) process. This can contribute to the production of microplastics.
In contrast, our additive attracts microbes and enhances their capacity to consume the polymer, fostering genuine biodegradation solely through a biotic process (biological rather than physical breakdown). As a result, it does not contribute to the formation of microplastics.
We advise adding 1% by weight of the final product. Some customers opt for a slightly higher percentage, such as 1.5 or 2%, to expedite biodegradation.
For multilayered products, include 1% additive in each layer.
For thicker products, please consult with SAWeco representatives to explore the possibility of adding more than 1% additive.
The SAWeco additive exhibits slight hygroscopic properties. It is advisable to keep the additive sealed when not in use. Generally, drying is not necessary for 201 pellets in most applications.
However, for PET applications, it is recommended to dry when using 202 and 203. In some instances, when utilizing 201 pellets in PET fiber and filament applications, drying may be required for optimal results. Refer to the separate Drying Instructions document for guidance.
Yes. SAWeco additive is safe for the recycling stream and the use of the additive does not change the recycling designation of the final product.
In adherence to regulatory requirements, most countries necessitate third-party biodegradation testing to substantiate claims of biodegradability. At BioSphere Plastic, we strongly encourage our customers to conduct testing on their final products.
Many choose to make claims, supported by third-party testing, specifically based on landfill conditions, given that this is typically the disposal environment. The ASTM D5511 (ISO 15985) method is commonly employed, simulating an accelerated or optimized anaerobic landfill setting.
Drawing from our experience, most products using BioSphere additive demonstrate a completed biodegradation cycle within 2-3 years, with some achieving it slightly sooner and others requiring a longer duration.
