A lot of environmental pollution and the resulting dangers for human life due to the increase of plastic wastes that have a long shelf life in the environment and also the dependence of thermoplastic synthetic polymers or plastics on fossil resources have caused attention to the possibility of biodegradation. Flexibility in plastics and also the use of renewable resources in the production of products needed by humans should be increased
Considering the approvals and significant government support and policies to reduce dependence on oil resources, the production and use of biodegradable polymers (from plant sources) is of great importance. Starch as a natural biodegradable polymer has many uses due to its reasonable price and availability. In our country, starch is known as the most important biodegradable polymer capable of industrial production. Starch-based biopolymers have greatly reduced environmental pollution, especially in terms of carbon dioxide emissions and energy consumption, compared to conventional polyolefin materials. ,
The use of film mulch to fight weeds, prevent soil compaction, prevent water loss, increase soil temperature and product quality has been common all over the world for years. Polyethylene films have been used as the best option in the production of mulch films in the past due to their suitable processability and low price, but due to the frequent use and replacement of these films in each cultivation period, concerns Much has been made about the use of these films, which are made from non-renewable and non-degradable resources. Due to the distance of farms from recycling facilities and equipment and the high cost of collecting these films, it is not possible to recycle them in most areas. For this reason, every year, millions of tons of plastic waste enters the soil in this way, and due to its long-term presence in the soil, it causes many pollutions, including the production of chemical compounds such as aldehydes and ketones, which have many side effects. .
Biodegradable products and plant films produced by Pardad Plast Maragheh company not only meet the needs of farmers as a film mulch, but also eliminate the concerns of soil poisoning and pollution due to the introduction of chemical compounds and plastics. will win The formulation of this production product is such that it is possible to adjust the degradation time and strength of the produced films based on the needs of the consumer.
The degradable film mulch produced by this company has the same functionality as polyethylene samples in improving the quality of cultivation and has all the advantages of conventional film mulch during the cultivation period. The degradable film mulch produced by this company has the same functionality as polyethylene samples in improving the quality of cultivation and has all the advantages of conventional film mulch during the cultivation period. The presence of plant and nitrogen compounds in these films can even improve soil fertility. Also, there is no need to spend money and time to collect film mulch from the ground after planting
The use of film mulch can reduce water consumption by 50% by reducing soil surface evaporation, preventing water wastage by weeds and preventing water wastage in the spaces between two plants.
