In 2018, Klabin’s construction project aimed at carbon reduction was responsible for the reuse of 25 tons of solid waste per month
Concerns about the environment are a recurring theme on the agenda of various sectors of society, especially in construction. Initiatives to promote a circular and low-carbon economy not only reduce the generation of solid waste and effluents and increase their reuse but are also at the forefront of discussions among companies seeking more sustainable management practices.

“We believe in the circular economy as the foundation for building a sustainable future. Today, we have numerous initiatives in this area, including various practices for reusing the waste generated in our operations.
To give you an idea, we currently achieve a rate of 97% of all waste generated in our operations being reused or recycled, and we have set the goal of achieving ZERO waste sent to landfills by 2030,” says Júlio Nogueira, from sustainability and environmental management at Klabin.
Klabin Aims to Reduce Carbon Emissions in Construction
In addition to a more environmentally correct waste disposal, more responsible solutions in various sectors of the economy represent fundamental actions for mitigating climate change.
In construction, 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 also aimed at construction is carried out at the Waste Treatment Station of the Puma Unit, which is also responsible for treating waste from the Monte Alegre Unit, which is transformed into blocks for paving or drainage, and can also be used in construction projects.
