In 2021, AVE managed 494.611 tons of waste / products.

The supply of waste for co-processing managed by AVE increased by about 2% reaching a volume of 494.611 tons, of which 271.112 tons were alternative fuels. There was a 11% decrease of secondary raw materials, which reached a quantity of 142.253 tons.

Overall, there was a slight increase of around 6% in the consumption of alternative fuels compared to 2021.

The most significant alternative fuels in the cement plants’ consumption are ‘RDF from industrial waste’, which represented about 128.561 tons in 2022. AVE also transacted 22.845 tons of Biomass streams during 2022, representing an increase of about 114,7% compared to 2021.

The mobilization of secondary raw materials (SRM), resulting from the activity related to current stocks, reached a total quantity of 142.253 tons. This represents a decrease of 11% when compared to 2021 (160.195 tons), which is mostly due to the decrease in managed of contaminated soils.

The supply of iron oxide, through the tailings and steel slags flows, comprised a total of 42.950 tons in 2022, representing an increase of about 10% compared to 2021.

The amount of avoided CO2 emissions was 223 thousand tons.

The amount of avoided Pet Coke amounted to 175 thousand tons.

Throughout this year, the national market continued to be the main source of alternative fuels and secondary raw materials supply of AVE, although it was necessary to resort to the import of waste with adequate technical conditions to respond to the consumption requirements of its customers.

The clarification of Alternative Fuels (AF) evaluation rules, based on a policy that provides a win-win relationship, has served as based for AVE – Gestão Ambiental e Valorização Energética’s proposals to be well received in by the enterprises, the economy and society of the country.

The market in which AVE is positioned has a huge challenge that involves the decarbonization of the cement industry, with the year 2022 marked by an increase in heat per ton of fuels supplied to cement kilns, accompanied by an increase in the biogenic component of these fuels. and a significant increase in the amount of secondary raw materials. The results presented in 2022 demonstrate the success of the assumed strategy, which should be pursued in the coming years, contributing to the creation of economic, environmental and social value.

During the year 2022, AVE maintained a dynamic and proactive attitude towards the sector in which it operates, namely regarding investment in research and development activities. In this way, in 2022, AVE continued to strengthen the technological resources associated with the laboratory activity and logistics of AVE in order to support its partners in the use of alternative fuels. In 2022, this was achieved with the entry into operation of new software that allowed to improve the report of the alternative fuels assessment, as well as the security in the database where they are registered. All these investments contributed to stimulating the competitiveness and sustainability of all its operations.

AVE’s laboratory analysed more than 1,250 products, guaranteeing a real-time response which allowed to improve the interaction with waste preparers and to quote the value of transactions with transparency. Sample collection actions were carried out and corrective actions were promoted with fuel producers, as well as communication channels between laboratories reinforced, clearly contributing to improve the quality and reliability of alternative fuels.

The completion of investments to support the logistics of alternative fuels consumption in the associated plants will allow to substantiate the increase in the substitution rate of fossil fuels.

The use of waste as fuel and / or alternative raw material contributes to the preservation of limited and not renewable natural resources. Despite being part of an industrial process, co-processing of waste in cement kilns does not imply any excess – since there is no residual waste – or any environmental liabilities.

This technique widely used in various countries around the world since 1976 is scientifically proven as one of the best environmental and economic solutions as final destination of numerous waste streams, assuming as a preferred solution for the sustainable development of contemporary society.
