Europlasma validates a technology that reduces the consumption of its vitrification processes by more than 40%

Europlasma, specialist in treatment and hazardous waste, material recovery and decarbonization, announces that its Chinese subsidiary Europlasma Environmental Technology (EET) has developed in its joint R&D center with Hangzhou Dianzi University an evolution of its vitrification processes allowing an energy gain of more than 40%.

A major quantitative leap in terms of energy efficiency

Work to optimize the Europlasma Group’s hazardous waste vitrification processes, initiated two years ago in order to adapt the furnaces to the particularities of the Chinese fly ash market (ultimate incineration waste), is in the completion phase. . Conducted within the Chinese subsidiary (EET) concomitantly with the processing of aluminum slag, they entered into “ pilot phase » following the authorization received from the Chinese environmental authorities.

A first test campaign, aimed at drastically improving energy consumption, has just provided experimental demonstration of the relevance of the physico-chemical analyzes and the simulation work carried out so far.

Indeed, in recent days, the work aimed at controlling the pre-treatment of waste, despite their large dispersion, has successfully lowered treatment temperatures by around 450°C, resulting in a reduction in consumption at the very least. energy at iso-furnace flow rate of more than 40% without altering the quality of the glass obtained, in particular with regard to leaching[i].

These results are to be credited to work to understand melting mechanisms within the Group’s furnaces, work which has accelerated since last November when the Group invested in its own multi-physics simulation capabilities (aeraulics, heat transfers, chemical reactions, acoustics) and new, faster experimental means.

Beyond a massive reduction in energy consumption, an essential economic and environmental issue, these results will have a significant effect on the life of the refractories, and therefore on the availability time of the furnaces.

It will be possible to quantify these gains by the end of this year, with hindsight on aging. In addition, the last quarter should also enable the validation of a new type of refractory, already efficient on a laboratory scale, both more resistant to chemical attack and considerably less loaded with chromium. Correlatively, these improvements should make it possible to reduce the price compared to current materials by at least a factor of three.

A process applicable to all Europlasma vitrification processes, with a major effect on their operating costs (OPEX)

This development of the Group’s historic vitrification process will be able to be applied to all processes currently in operation as well as to those to come (sludge from the oil industry in particular). In energy-consuming activities, it considerably reduces their operating costs (OPEX).

It also demonstrates, after the results obtained on the treatment of aluminum dross at the end of April, the first concrete benefits of the work to develop a treatment concept (“ Gasket Waste Treatment “) original integrating synergies between different types of waste. This systemic approach will make it possible to reduce additive and energy inputs, illustrating, once again, the Group’s ambition to develop and improve pollution control solutions that respect the environment with a broad spectrum vision.

Pascal Gilbert, Managing Director of EET and Director of Europlasma declares : These advances are essential at a time when energy sobriety and circular economies are becoming global concerns. They constitute a crucial step in consolidating our position as leader in our areas of excellence, and in addressing not only niche markets, but global operators who currently have no other solution than the (temporary) storage of their hazardous waste. We are pleased that the innovative knowledge acquisition approaches of the past two years are reaching maturity, and are confident about the results expected in the coming months, due to the robustness of the approach followed. These results are in line with the Group’s roadmap, as defined three years ago. To In this regard, I would like to underline the richness of the cooperation between the technical and scientific cultures involved in R&D work both in Europe and in China. It is this cooperation that has enabled these significant advances. It constitutes an intangible wealth of the Group consubstantial with its investment policy in progress “.


Europlasma is a French group expert in depollution, whose know-how for 30 years is based on its proprietary technology, the plasma torch, allowing very high temperatures to be obtained. Europlasma’s business consists in designing and developing the numerous applications of the plasma torch, at the service of man and his environment. Its innovative solutions are intended for the treatment and recovery of hazardous waste and gases as well as applications for industries concerned with reducing their environmental footprint. At the same time, Europlasma has deployed a CSR (Solid Recovered Fuels) preparation activity, based on its unique know-how developed on its Morcenx site. The EUROPLASMA share is listed on Euronext GROWTH™, (FR0013514114-ALEUP / LEI 969500WYVNHBV1ABQ250). For more information :
