Sustainability Report

Unipar presents the second edition of its Sustainability Report, which follows up on the goals presented in the previous edition, in addition to enhancing existing commitments. The content was prepared according to the guidelines of the Global Reporting Initiative (GRI), which represents the best global practices for public reporting in the environmental, social and governance fields. The topics prioritized in the document are in line with Unipar’s sustainability strategy and the Sustainable Development Goals (SDGs) adopted by the United Nations.

Sustainability is part of the company’s business strategy, mission and values. Two years ago, we redefined our positioning in sustainability: we want to be “an agent of transformation for a sustainable future”, mobilizing our ecosystem to extend the reach of our initiatives.

By 2030, R$ 1.4 billion will be invested in around 30 projects listed in our roadmap. These initiatives have an impact, are aligned with the company’s strategy, generate economic return and are part of our short and medium-term public commitments.

Practices adopted by both Unipar and the chemical industry are fully committed to protecting the environment and to the certifications that attest to its safety. This commitment guides the performance of the company, founded 54 years ago. Unipar maintains strict policies regarding the environment, even before legal requirements.

Sodium Hypochlorite Reactor

 Hypochlorite is produced by a reaction between gaseous Chlorine and a Caustic soda solution being cooled down.

17

EDC Reactor

EDC (Dichloroethane) is obtained through a reaction between liquid chlorine and ethylene (inserted through a tube) and it is purified by distillation.


15

Hydrochloric Acid Reaction Furnace

Hydrochloric acid is produced by a controlled combustion reaction of Chlorine and hydrogen, followed by absorption in treated water.

13

Evaporation

Caustic soda is produced by electrolysis and reduced through the evaporation process.

14

Cooling

 Then, the Soda is cooled down and stored in tanks, before being shipped.

Phases

(8) Cooling Chlorine

(9) Chlorine Withdrawal

(10) Chlorine Compression

(8) The produced gaseous chlorine is cooled down, (9) dried out and (10) compressed. After being compressed, it turns into a liquid state at low temperature.


Stages

(3) Treatment

(4) Filtration

(5) Control

(3) The PICKLE is about eliminating foreign bodies; it is filtered (4) and undergoes a strict control (5) before feeding the ELECTROLYTIC CELLS.

Etapas

(3) Tratamiento

(4) Filtración

(5) Control

(3) La salmuera se trata para eliminar impurezas, se filtra (4) y pasa por un estricto control (5) para alimentar las CÉLULAS ELECTROLÍTICAS.

Start

If there are salt (sodium chloride) and water in stock, you need to supply our transformers with electricity.

Etapas


(11) Licuefacción de Cloro

(12) Almacenamiento de Cloro

(11) El cloro en esta forma se almacena en tanques (12) donde se carga en camiones especiales

6

Sala de Celdas

La ELECTRÓLISIS tiene lugar en la celda. Y así, la energía eléctrica actúa sobre la salmuera y la transforma en SODA CÁUSTICA, CLORO E HIDRÓGENO.

Evaporação

A Soda Cáustica é produzida na eletrólise e concentrada pelo processo de evaporação.

6

Cell Room

The ELECTROLYSIS takes place in the cell. This way, electric energy acts on the brine and transforms it into CAUSTIC SODA, CHLORINE AND HYDROGEN.

Etapas

(3) Tratamento

(4) Filtração

(5) Controle

(3) A SALMOURA é tratada para eliminar impurezas, filtrada (4) e passa sob um rigoroso controle (5) para alimentar as CÉLULAS ELETROLÍTICAS.

Pickle

Next, prepare the PICKLE obtained from dissolving the salt in the water to use afterwards in the ELECTROLYSIS.
