Project Summary

For over half a century growers/farmers have been using plastic materials in agriculture, also known as agro-films. Current existing semi-intensive and intensive farming practices require the use of large quantities of mulching film and fruit protection bags (and clips to close them) since they help prevent the growth of weeds, protect crops from insects, regulate soil and produce temperature and retain water and nutrients. These plastics have replaced paper for the mulching of vegetables because of their affordability and easiness to apply in the field. The best-known type of plastics used for agricultural films are low and high density polyethylene (LDPE and HDPE respectively). Conventional non-degradable polymers after single-use become plastic waste, creating a serious problem of waste management since it is time-consuming and expensive to recycle. This plastic waste is usually abandoned, incinerated or taken to a landfill. These practices have serious consequences for the environment. Therefore, governments and farmers demand cost-efficient, environmentally responsible solutions. The total consumption of plastic films for agricultural purposes in Europe exceeded 500 000 tonnes in 2013. 

Project Objectives

The consortium aims to address three specific objectives: 1. Development of new biodegradable plastics films with very low carbon footprints: conventional agricultural plastic films have an enormous environmental impact in terms of CO? emissions during their lifecycle. The project will significantly reduce this impact because its biodegradable polymers and additives will be made from renewable raw materials that are not petroleum-based and do not compete in food markets. Also, biomass for these biodegradable plastics will come from trees and crops that extract CO2 from the atmosphere as they grow; 2. Elimination of waste management: the Multibiosol bioplastics will break down naturally (with OK biodegradable SOIL certification) so removal and transportation of the waste will no longer be needed. Costs of management for farmers/growers and the environmental problems associated with landfills and incineration will be eradicated; and 3. Improvement of soil and product quality: conventional agricultural films have toxic components and contaminate the soil in a number of ways. Multibiosol bioplastics will not only avoid these harmful components, but they also will add value through oligo-elements (trace minerals as natural fertilizers) and micro-perforation functionalities that contribute to agriculture à la carte and help improve the health of the soil and the quality of the final product.

Project Implementation Method

We will provide all the necessary raw materials to the factory producing these biodegradable plastics and will receive the final products from them and then we will supply these products to the markets (only in Swat valley in the Start) as alternatives of polyethene products.

Benefits of the Project

• The development of cost-effective and biodegradable ‘third generation’ plastic films for agriculture that allow for sustainable and efficient farming practices;
• A 100% waste reduction due to the complete biodegradability of plastics (OK biodegradable SOIL label) after being tilled on soil;
• Reduction of CO? emissions of 50%, since the biodegradable plastics will not use fossil fuels as raw materials and emit fewer carbon emissions during production. This number also takes into account the cuts in transportation and incineration related to waste management, as well as carbon capture from trees and crops which extract CO? from the atmosphere as they grow;
• Competitive market solution for biodegradable plastics: the price of the plastics will be competitive, particularly when taking into account that there will be significant savings for farmers in waste management and that demand for biodegradable plastics is expected to increase as its costs lower. Furthermore, farmers will be able to tap into a growing demand for sustainable products;
• A 15% improvement in soil quality since oligo elements will act as natural fertilizers and petrochemicals plastic contamination will be avoided;
• A 10% improvement in crop quality due to the improved fertility and quality of soil; and
• Increased awareness and dissemination of sustainable practices on waste management among stakeholders (particularly on relevant EU legislation and objectives).

Technical Details of Final Deliverable

These biodegradable plastics contain additives that cause them to decay more rapidly in the presence of light and oxygen (moisture and heat help too). Unlike bioplastics, biodegradable plastics are made of normal (petrochemical) plastics and don't always break down into harmless substances: sometimes they leave behind a toxic residue and that makes them generally (but not always) unsuitable for composting.
