Bioplastics also cause carbon dioxide emissions from harvesting vehicles. [59] Other minor environmental impacts include high water consumption for biomass cultivation, soil erosion, soil carbon losses and loss of biodiversity, and they are mainly are a result of land use associated with bioplastics. [64]
This conservation of water makes plastic mulch favourable for farmers in dry and arid climates where water is a limited resource. As the second most used ag plastic in the world, the volume of plastic mulch used every year is estimated at 700,000t.
The definition of bioplastics is still up for debate. The phrase is frequently used to refer to a wide range of diverse goods that may be biobased, biodegradable, or both. This could imply that polymers made from oil can be branded as "bioplastics" even if they have no biological components at all. [5]
To confirm that the microorganisms being studied are attracted to a certain type of plastic, it is important that the synthetic plastic is the only source of carbon in the experimental compost or soil. [9] If there is a significant release of carbon dioxide, it means that the microorganism has successfully consumed the carbon in the plastic.
Polyethylene or polythene film biodegrades naturally, albeit over a long period of time. Methods are available to make it more degradable under certain conditions of sunlight, moisture, oxygen, and composting and enhancement of biodegradation by reducing the hydrophobic polymer and increasing hydrophilic properties.
As technology has improved and the cost of parts has decreased over the last two decades, underwater robots have begun to play an important role in exploring and working in harsh aquatic conditions.

In typical parlance, the word biodegradable is distinct in meaning from compostable.While biodegradable simply means an object is capable of being decomposed by bacteria or other living organisms, "compostable" in the plastic industry is defined as able to decompose in aerobic environments that are maintained under specific controlled temperature and humidity conditions.
