Plastic pollution is a global challenge that requires fresh thinking and innovative solutions. Bioplastic addresses environmental issues associated with traditional plastic.
This blog post will explore what bioplastic is, how it is produced, the materials it is made from, and how long it takes to break down.
Bioplastic is a type of plastic that differs from conventional plastic by being based on renewable resources such as plants and microorganisms. This makes bioplastic more sustainable and biodegradable compared to petroleum-based plastic types. The increased attention to bioplastic is due to its potential to reduce the negative environmental impact of traditional plastic.
The production of bioplastic involves the use of bio-based raw materials, which can include starch, sugars, vegetable oils, and microorganisms such as bacteria or yeast. The most common method for producing bioplastic is fermentation, where microorganisms convert sugars into polymers. This process can be more environmentally friendly and sustainable compared to extracting oil for conventional plastic.
Bioplastic can also be produced using thermoplastic polymers, which can be shaped and processed similarly to traditional plastic. These polymers can be extracted from plants such as corn, sugarcane, and potatoes, and processed to form various types of bioplastic.
Bioplastic can be based on various materials depending on the intended use. One of the most common sources for bioplastic is cornstarch, which is converted into polymers and used to create biodegradable products. Sugarcane is a sustainable source for bioplastic production and can be used to make different types of bioplastic with varying properties. Starch from potatoes can be extracted and used to create bioplastic materials with good mechanical properties. Microalgae can be an alternative source for bioplastic and offer the advantage of not competing with food production. Oils from plants such as soy, corn, or rapeseed can be used as raw materials to produce bioplastic.
One of the significant characteristics of bioplastic is its ability to break down more efficiently than traditional plastic. However, the degradation process depends on several factors, including the type of bioplastic and environmental conditions.
Bioplastic can break down in industrial composting facilities, where temperature and humidity are controlled to optimize the degradation process. Under these conditions, certain types of bioplastic can break down in as little as a few weeks to a couple of months. It is important to note that degradation in home composting conditions or in nature may take longer, and some types of bioplastic require specific conditions to break down completely.
