Waste treatment and carbon sinks

Fossilizator® are industrial facilities capable of processing up to 100,000 tonnes of waste per year. The entirely mechanical process requires no heating, and emits no odors, fumes or wastewater.

To take a closer look at this unique cold process, here’s the sequence of events :

1: Shredding consists in reducing waste to a fine scale called Fossilizate® (grains between 0 and 500 microns).

2: Mixing involves reacting the Fossilizate® waste with binders to mineralize the material. At the end of this reaction, we obtain a kind of mineral modeling paste. The binders we use at this stage are formulations that we have developed and produce ourselves.

3: Shaping consists in pressing and shaping this mineral paste to obtain aggregates of the desired shape and density.

In the end, aggregates are both construction resources and carbon sinks, sequestering the biogenic content of waste.

Accelerated Fossilization industrial process

Stage 1

Waste sorting

Accelerated Fossilization treatment applies to non-recyclable, non-inert and non-hazardous waste such as WAS, bulky waste and all waste from waste collection centers (R&D underway on household waste).

Stage 2

Materials selection

This stage consists of removing recyclable materials from the stream and reducing waste to Fossilizate®.

Stage 3

New material

This stage involves reacting Fossilizate® with a mineral binder to produce Anthropocite® aggregates. This non-hazardous binder was developed and is produced by Néolithe.

Stage 4

Use in construction

Anthropocite® aggregates can be used as a substitute for natural aggregates from quarries, in non-structural concrete or as bituminous gravel, without any technical or environmental risk.

Our first pre-industrial site

To recycle the sector’s mixed non-recyclable waste, Valolithe partners Néolithe, Courant, Hervé and ERB have set up a sorting center and a Fossilizator® in Avrillé (49240).
