Green Earth Green Sunward

Shanghai Sunward adopted the world’s first biodegradation technology that is able to biodegrade polyolefin packaging material completely in an open-air environment, making biodegradation come true.

There are three phases:
Phase 1:
Storage and usage. In this period, the technology is not activated. The way of its packaging is the same as how other non-biodegradable material pack. The typical period is 6-36 months.
Phase 2:
Convert to wax. After life cycle, in the environment where heat, air, moisture and sunlight are present, the material is convert to wax chemically at fast speed. The typical period is 3-7 months.
Phase 3:
Bio conversion in open-air environment. Bio-available wax will bio-convert via bacteria, fungi, etc. which exist in the soil in open-air environment. The typical period is 12-24 months.

Sunward Biodegradability VS Other Biodegradability

Sunward is always caring about white plastic pollution, constantly exploring solutions to solve problems of white pollution, contributing to environment protection.

Sunward Biodegradable material

Other Biodegradable material

Sunward biodegradation end up with water and carbon dioxide.

Sunward biodegradation takes place in open-air environment where light, air and mosture are present.

The product density is 0.92

Other biodegradation end up with microplastic

Other biodegradation only takes place under composting condition

The product density is 1.2

Sunward Biodegradability Advantage

Completely Biodegradable

In terrestrial environment, the advanced catalyzing system will convert PP and PE to bio-available wax chemically. Naturally-occurring microorganism will bio-convert wax without microplastic left behind.

Certificate&Standard

Passes international biodegradability standard (PAS9017) test based on EN, ASTM and ISO standard, complies with Chinese GB/T 22047-2008 and ISO17556-2003 standard, also fulfills eco-toxicity requirements of OECD208, 222, and 211 standards.

Intact physical properties

Biodegradable products can maintain the original mechanical properties.
In valid period, the products can be used as normal to fulfil package requirements with no needs to change any production process
