Klabin’s project transforms sludge into bricks for use in construction

In 2018, the project was responsible for the reuse of 25 tons of solid waste per month

São Paulo, September 11, 2020 – Concern for the environment is a recurring topic on the agenda of various sectors of society. Initiatives to foster a circular and low-carbon economy not only reduce the generation of solid waste and effluents and increase their reuse, but also figure at the forefront of discussions of companies seeking more sustainable management practices. Klabin, which is committed to incorporating these solutions into its operations, from forestry to packaging, has an array of projects for reusing its waste products. One such project uses the sludge created in the wastewater treatment process to make bricks for use by the construction industry. 

The project, which was launched in 2018, was developed by the Environmental team of Klabin’s Rio Negro Unit in Paraná state, with the support of the Sustainability and Research & Development corporate teams. As a result, 25 tons of waste per month have received a new application, being reused even in the company’s own construction projects.

 “We believe in the circular economy as a cornerstone for building a sustainable future. Today, we have countless initiatives on this front, including various practices for reusing the waste generated by our operations. To give you an idea, today we have achieved a rate of 97% of all waste generated by our operations being reused or recycled, and have set a target of reaching ZERO Waste sent to landfills by 2030,” said Júlio Nogueira, Klabin’s sustainability and environment manager.

In addition to more environmentally friendly waste disposal, more responsible solutions by various sectors of the economy represent key actions for mitigating climate change. In the construction industry, for instance, according to research, the use of concrete currently accounts for 8% of carbon emissions. The search for alternatives that cause lower environmental impacts is aligned with the low-carbon policies increasingly adopted in various countries.

Another important initiative that also centers on the construction industry is carried out at the Waste Treatment Station of the Puma Unit, which also is responsible for treating the waste of the Monte Alegre Unit, which is transformed into blocks for pavement or culverts, and also can be used in construction projects.

This Klabin project, as well as others, aim to make a significant contribution to the achievement of the UN Sustainable Development Goals, to which the company voluntarily became a signatory, in 2016. The project specifically addresses the SDGs 9, 11, 13, 15 and 17, which are related, respectively, to Infrastructure, Sustainable Cities & Communities, Climate Action, Brazilian Biomes and Partnerships and sustainable development implementation methods.
