Plastic emissions from mulch film and abatement measures - a model-based assessment for Germany

Résumé

Plastic mulch film application in agricultural production creates a debate between environmentalists and farmers. Mulch films are disturbing elements in the landscape and fauna habitats and cause plastic emissions. Farmers apply the mulch film to specific crops to optimise production conditions and reduce factor input and environmental impacts. In Germany, mulch film allows timely production according to the consumers’ demand for asparagus, strawberries, lettuce, cucurbits, and early potatoes. Mulch film application and plastic emissions differ regionally and are high for regions where farmers are specialised in producing specific crops (e.g. gherkins). Representative statistical data on mulch film applications do not exist. Thus, the assessment of plastic emissions and abatement measures is challenging. This paper presents a conceptual framework to quantify the plastic emission from mulch films and economically evaluate abatement measures. Increasing the thickness of mulch film can reduce the emissions from plastic mulch films and maintain the advantages in production processes. In abatement scenarios, increasing the film thickness to 40 to 50 micrometres reduces plastic emissions by 20 to 40 per cent. The abatement costs reach from 120 to 130 Euros per kilogram of abated plastic. Transmitting the abatement costs to the consumer would increase the price by 1 to 10 per cent. Thus, increasing the film thickness in Germany could be an economically interesting abatement measure if consumers are willing to pay 1 to 10 per cent higher prices for products produced with less plastic emissions.
