Plasticulture is the use of plastic mulch in agriculture. Farmers use plastic sheets as mulch to cover 50-70% of the soil and allow them to use drip irrigation systems to have better control over soil nutrients and moisture. Rain is not required in this system, and farms that use plasticulture are built to encourage the fastest runoff of rain.
Since its introduction in the 1950s, plastic film has been designed and developed to increase produce yield, increase produce size and shorten growth time. Developments in plastic film include durability, optical (ultraviolet, visible, near infrared, and middle infrared) properties, and the antidrip or antifog effect.
According to the waste hierarchy, burning agricultural waste for the sake of energy generation is a less environmentally friendly treatment method than recycling or reusing it. Moreover, incineration for energy generation can be done once, while consumer goods (such as paper made from agricultural waste) can be recycled another seven times. [ 26 ]
A study from 2024, using the Break Free From Plastic dataset, found that of the aforementioned 50% of the waste that was identifiable by brand, 11% was attributable to Coca-Cola, 5% to Pepsico, 3% to Nestle, 3% to Danone, and 2% to Altria, totaling 24% of the total branded count. 56 companies accounted for over 50% of the branded items.
Plastic recycling is the processing of plastic waste into other products. [ 1 ] [ 2 ] [ 3 ] Recycling can reduce dependence on landfill , conserve resources and protect the environment from plastic pollution and greenhouse gas emissions.
Crop residues are waste materials generated by agriculture. The two types are: Field residues are materials left in an agricultural field or orchard after the crop has been harvested. These residues include stalks and stubble (stems), leaves and seed pods. Good management of field residues can increase efficiency of irrigation and control of ...
Air pollution caused by agriculture through land use changes and animal agriculture practices have an outsized impact on climate change. Addressing these concerns was a central part of the IPCC Special Report on Climate Change and Land [3] as well as in the 2024 UNEP Actions on Air Quality report. [4]
Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations ...
