Fossil: Naphtha and natural gas arrive at the Braskem plant, where they receive a more refined treatment. From this process, Ethylene and Propene are produced, fundamental raw materials for the second step: polymerization, which is also controlled by Braskem. In this stage, the units receive Ethene to produce Polyethylene or Propene to become Polypropylene. In addition to Ethene and Propene, Braskem produces a number of chemicals, such as solvents.

Renewable: In Braskem's plants, ethanol is dehydrated, giving rise to Ethene. From this, the renewable ethylene goes through the same process as the fossil Ethene to produce Polyethylene.

Brine: The raw material gets to Braskem's units along with Ethylene, which will give life to Vinyl Polychloride, PVC, a material used in pipes, among other applications. In addition to PVC, these units produce other chemicals such as Sodium Hypochlorite and Hydrochloric Acid.

In a globalized world, logistics systems are fundamental. The productive stages usually occur in different geographic locations; hence they require a means of transportation so that materials are moved from one point to another. The most common transport modes are: road, rail, waterway, maritime, air and pipeline. The efficiency of the modal depends on the type of product, distance and quantity transported, so it becomes a specific solution for each case.

In order to transform the resins that Braskem produces, there are several methods of modifying a polymer. Generally, they all involve the heating and pressure of the resin on a mold or matrix that will give rise to the part.

The plastics transformation stage has a smaller scale than the preceding steps. Nevertheless, the related impacts can be significant mainly due to the energy consumption of the transformation industries. More efficient polymers, for example, reduce the amount of energy consumed and increase the productivity of transformers, and this improves performance not only from a process point of view, but also from the environmental one.

The time has come for the plastic to show what it is here for, and at this stage it demonstrates its greatest benefits, such as low density and electrical conductivity, as well as flexibility and durability, which explain its efficiency in various applications.

In the case of basic chemicals, they can be transformed into other plastics, paints, pesticides among others.

Examples:

Automotive: It decreases vehicle weight by reducing fuel consumption. It also reduces water losses.

Sanitation: The material facilitates and reduces the need for maintenance. It also reduces the price of the part, water losses and helps to universalize basic sanitation.

Packaging: It prevents waste of food.

Society and businesses have a responsibility to manage the solid waste they produce and the products they consume. Within our units, the generation of waste is controlled by an ecoindicator. For the market, with initiatives from Wecycle, we also seek to incorporate Braskem's business as part of the solution for the mechanical recycling of plastic.

There are today 4 types of residues treatment:

Chemical Recycling: When plastic becomes a basic chemical, such as naphtha;

Energetic Recycling: When the residue is burned in a controlled environment (such as a boiler or furnace) to generate energy;

Mechanic Recycling: When the residue returns to the processing industry and is converted into a new product;

Landfill: When the residue goes to landfills, the plastic remains inert for many years in this case.
