The multinational company Masias Recycling has developed a technological solution under Covertech system through which municipal solid waste (MSW) can be transformed into a dry matter with high calorific value that can be used as solid recovered fuel (SRF) in those industries that are highly dependent on energy, such as the cement or the electrical industry. Covertech Biodry improves the LCV (low calorific value) of waste by 70% by means of biodrying.
The aim of Covertech is part of the concept included in the parameters of the Circular Economy Package adopted by the European Union, which seeks the development of closed loop business opportunities and that shall foster an economic growth that is not to be linked to fossil resources. Nowadays more than 50% of the municipal solid waste (MSW) still ends up in landfills. This percentage is much higher in developing or emerging countries, where this can reach 90%. In the best-case scenario the material sent to landfill is biostabilised so as to reduce the pollutant effect this may have, but it is finally buried without it being given an alternative use and without it being introduced in the economic cycle. In this way, the waste sector is responsible for 5% of the total greenhouse gas (GHG) emissions, being one of its main causes the decomposition of the organic matter in the landfills.
A large number of industries need energy, and still a great quantity of valid resources is buried. At the same time, the planet needs the consumption of fossil resources to be reduced, and it is clear that this sector can help to the GHG decrease. “The aim is to reach landfill diversion by getting a material capable of being used as fuel, while offering our technology to reduce GHG emissions as much as possible”, says Jordi Sala, CEO in Masias Recycling.
In order to give an answer to these needs, and facing this reality, the company has spared no effort to develop a technology that shall be capable of transforming tons of waste into SRF with high calorific value, focusing on the wet fraction of the waste. “We can offer complete solutions by means of Covertech, as the organic fraction is still 50% of all generated waste”, declares Frederico Contente, Key Account Manager of the company.
The purpose of Covertech Biodry is thus to transform MSW with a humidity of 40%-70% into an alternative fuel with a humidity below 20%. In this way, we can reach a high calorific power material, which shall replace fossil fuels and be used as alternative fuel. “Is it really so that all material that is buried in landfills has no value? We are sure it does have some value and thus we focus on that through biodrying”, states Contente. So as to get an optimal outcome, Masias Recycling counts on INCABO as technological partner. This company manufactures fabrics for technical applications since 1959, having been able to combine the best technical features of the fabric in the FR-COMPOSPLY covers used in Covertech system, with Masias’ know-how in the biological treatment of waste.
Masias’ Covertech biodrying technological process is based on the decomposition of the organic matter so as to increase temperature, thus speeding the drying process. That is done with some added value: cost and space reduction due to the efficiency of FR-COMPOSPLY cover, which has been exclusively developed for this process. “Results we get with Covertech Biodry show an increase of about 70% of the calorific value for industries such as the cement or the energy thermal one”, says Contente. Moreover, the customer gets an optimum investment-operational expenses relationship, which leads any other process there is in the market.
Fuel generation from MSW is a profitable alternative to those non-renewable fossil energies. Biodrying is a relatively new sustainable technology, born just about two years ago. “It is still quite a minority technology, but its potential and possibilities are unlimited. The World Bank in particular estimates that municipal waste generation will increase up to 2.2 billion tons per year in 2025, with a growing trend”, adds Contente.
