Mulch film is widely used in modern agriculture providing a number of benefits for crop growth and yields. At present, China is the world’s largest country in the amount of mulch film used with approx. 1.5 million tons annually. However, only 40% of the used mulch film are collected from fields. The residual film discarded in the farmland has caused serious “white pollution” in Chinese agriculture, which adversely affects the crop yields. The Sino-German Project for Upgrading Plastics Management in Agriculture seeks to improve the management of plastic mulch film in China by enhancing the recycling efficiency of PE mulch film and promoting the utilization of biodegradable mulch film.
Dingxi city is located in the typical semi-arid and arid farming area. Hence, mulch film plays an indispensable role of moisture conservation for agriculture activities, the majority of which being PE (Polyethylene) mulch film. The project aims at application of digital tracking system for PE mulch film for corn production in Dingxi city, with a demonstration area of 500 mu (ca. 33 ha), in order to not only achieve a data-based monitoring and closed-loop management of mulch film along the whole value chain, but also improve the recycling efficiency of PE mulch film.
