Braskem is the leading global producer of bio-based plastics. Our bio-based plastic is plastic made from sustainably sourced, sugarcane-based bio-ethanol which removes CO2 from the atmosphere and stores it in products for daily use.
Sugarcane: a renewable source of sugar, plastic and energy
What is bio-based plastic?
Bio-based plastics are made from plants, such as sugarcane and corn. At Braskem, we produce bio-based plastics from sugarcane in Brazil. At the plantations, sugarcane is harvested and processed by a mill where the sugarcane is crushed up to five times. In modern mills, the first press is mostly used to produce sugar. Subsequent presses extract residual sugars in order to create ethanol. This ethanol eventually becomes the raw material from which bio-based plastic is made.
The production of ethanol is not at the expense of the production of sugar, rather, it means that more of the plant is being used.
In fact, a purpose is attributed to every byproduct! After the sugar is completely removed from the sugarcane, the left over fibers are fed to a power plant that generates heat to boil the sugar juice. Moreover, it generates electricity to power the mill. The excess power often helps powering the national grid, reducing our dependency on fossil fuels. Finally, all other residues are circled back to the plantation as a source of water and nutrients, reducing the need for inorganic fertilizers that can have a high carbon footprint. What is key however, is that sugarcane is a renewable and unlike fossil raw materials, it grows back every season!
Plastic that stores
more CO2 than it emits
By producing ethanol from sugarcane, we do not only reduce our dependency on fossil resources, we also capture CO2. Through photosynthesis, sugarcane takes CO2 from the air and a portion of this CO2 is locked into bio-ethanol, the basis of our bio-based plastic.
How does that work?
At Braskem, the bio-ethanol is dehydrated and broken down into ethylene and water. The ethylene is then polymerized into plastic resins within our plants. Up to now, we have been producing different types of polyethylene and EVA. Bio-based polyethylene is used in many applications, such as packaging and toys. Bio-based EVA for example is widely used in foams such as shoe soles. As these products store CO2 from the sugarcane, Braskem's bio-based plastic has a negative carbon footprint, storing more CO2 than it emits.

The term bio-based plastics and bioplastics are often used interchangeably, which is incorrect. Bioplastic is an umbrella term that refers to all plastics that are either bio-based, biodegradable or both. While bio-based says something about the origin of the product, biodegradable refers to its end-of-life.
Biodegradation mainly offers advantages for applications where recycling isn't possible or economically viable. Biobased plastics from Braskem are 'drop-in', which means that their molecular composition is exactly the same as that of regular plastic. This means they can be converted into a new product again in the regular recycling flow and in the circular value chain.

Examples of Braskem’s bio-based plastic
Braskem has partnered up with Join the Pipe to distribute sustainable and reusable water bottles made with I’m Green polyethylene in Europe, Africa and the U.S. The income generated from the product will be intended for over 300 social projects in developing countries, most of them in Africa and Asia.
Bottle Up and Braskem partnered up to deliver reusable water bottles made from I’m Green polyethylene. This way, Bottle Up not only transitions the product bottles from being single-use to multi-use, but they also significantly reduce the carbon footprint of the product. Bottle Up bottles are sold at popular locations like Albert Heijn, Jumbo, WHSmith, Stach, HEMA, Holland&Barret, BP, Coop and more.
Braskem and Polytan provide I’m Green polyethylene for the hockey fields for the Olympic Games in Tokyo in 2020 and the 2022 hockey World Cups. Using this material for the artificial turf production delivers the same turf quality, whilst making a positive impact on hockey fields’ carbon footprint.
