Conforming to ASTM-D6400、EN13432 Criterion, passed BPI and DIN-CERTCO certification;
The biodegradation rate was 99.7% in 180 days;
PCO2 biodegradable mulch is a new-type film used to cover the soil which raises the temperature of soil, maintain the moisture and the structure, prevent pest from attacking crops and stop diseases caused by certain microorganisms. It is helpful for plants’ growth.
PCO2 biodegradable mulch film can be customized according to different needs of plants and different soil conditions.
PCO2 biodegradable mulch film will degrade to water and carbon dioxide, which is friendly to environment. As it doesn’t need to be recycled, it will reduce the use of labor.
The wide application of mulch film technology has brought enormous economic benefits while at the same time leading to severe soil pollution.
The amount of residual film is increasing year by year and the pollution is becoming more and more serious. Two ideal ways to solve “White Pollution” problems are using 100% biodegradable film and easily-recycled film with high strength.
Dosage of film (kg/mu) | Cost of film(yuan/mu) | Mechanized recycle cost(yuan/mu) | Cost of labor to collect film(yuan/mu) | Total cost(yuan/mu) | Recycle rate(%) | |
Biodegradable film | 7.5 | 180 | 180 | 100% degradable | ||
Recyclable film with high strength | 5.5 | 90 | 30 | 50 | 170 | >95% |
Common film | 5.5 | 66 | 30 | 50-100 | 146-196 | <60% |
1. Biodegradable film
The degradation time can be adjusted to a controllable range according to the growth cycle of crops.
It is beneficial to green, ecological and sustainable development as the abandoned films will degrade to CO2, H2O and small organic molecules.
Production process of biodegradable film
The mulch film paving conditions in Gansu and Xinjiang Production and Construction Group in last three years
2. Weather-proof film
With characteristics of high strength, good weather-proof and can be recycled by machines
Recovered film after crop can be processed and turned into functional construction materials like floor tiles and wooden decorationsmaterials.
