Create a circular economy for your solvents
Speichim Processing and Valls Quimica, subsidiaries of Séché Environnement, lead the European market in solvent regeneration.
We harness our expertise and operational proficiency in chemical distillation to separate solvents from other components to produce a solvent of comparable quality to the virgin product.
We adapt our processes depending on the properties of the product that requires treatment, providing custom work. Our clients operate in a variety of industries, including pharmaceutics and veterinary services, cosmetics, perfume, agro-chemical, petrochemical, fine chemical, automotive, aeronautic, printing, varnish and coloring and thermosolar.
With 5 specialist facilities across France and Spain, we have developed a recovery channel for your residues, making it possible to reuse solvents once they have been regenerated. Our solution minimizes the use of fossil resources and eliminates the need for incineration. It means exhausted solvents no longer need to be considered as waste, instead becoming a resource, which therefore cuts your carbon footprint. Indeed, regenerating solvents creates 80% less emissions than producing virgin solvents from hydrocarbons.
Our regenerated solvents present the same properties as their virgin counterpart, and can be reintegrated into their original process (you conserve ownership of your product), or be redirected to a new use in industry (we take ownership of the solvent).
Our main regenerated solvents:
- Oxygenated solvents
- Hydrocarbon solvents
- Halogenated solvents
- Sulfur solvents
- Amine solvents
- Amide solvents
We also regenerate other products, including monomers.
Furthermore, we provide services covering all technical and regulatory aspects (sorting, transport, substitution of hazardous solvents, etc.).

Custom work makes up the largest proportion of service s we provide numerous manufacturing industries. The treatment capacity across our five industrial facilities in Europe enables your to safely outsource your solvent regeneration loops.
Regenerating solvents invariably requires complex planning, specifying in particular the duration of the production cycle, planned shut-downs, upstream and downstream storage capacity, distances between plants, regulatory. Our teams visit your premises to consider the most effective solutions for your needs. We also deliver in tanks, isotanks or platform trucks. Moreover, we offer conditioning in IBCs and/or barrels, even for temperature-sensitive products.
Managing a solvent loop is often a delicate operation. Whether the solvent is used continuously or periodically, the process requires skills is a variety of areas:
- Logistical: we make regular deliveries and collections all over Europe, using our fleet of iso-containers, our fixed storage facilities and our relationships with several international logistics partners.
- Operational: we excel in regeneration, maximizing output and quality.
- Organizational: we provide the exact quantities of new solvents you require at the best price.
Regulatory: we check waste flows and have reliable disposal channels.

How we operate
Regenerating exhausted solvents in four steps.
Project feasibility study
We conduct a personalized assessment of the products, safety studies and toxicology, risk assessment and change control.
We conduct a personalized assessment of the products, safety studies and toxicology, risk assessment and change control.
R&D assessment and analysis
After having considered the project feasibility and accepted the project, we set out the process. We test the critical impurities and parameters, as well as the temperature-sensitivity, solubility and cleaning, determining the most suitable treatments.

Pilot test
We run a pilot and an initial pre-industrial trial in the lab to ensure the process is viable. The distillation procedure is approved and we collect feedback.

Industrial-scale treatment
We follow the most suitable procedures in the full-scale distillation process, including atmospheric pressure, azeotropes, extraction, vacuum, reactive, and molecular. Distilling and recovering solvents produce outputs of around 90%. At the same time, we offer to bridge this gap with virgin solvents to maintain the quantity and quality of your supplies.

Certifications
We have always sought to improve our practices, measure our impact on the environment and achieve the highest standards with respect to energy and environmental performance.

Reasons to place your trust in us
End-to-end support
We have been distilling chemicals for over 50 years. The success of each operation relies on comprehensive analysis and lab trials, followed by a preindustrial pilot. We support you throughout your project across all technical, logistical and regulatory aspects. Our end-to-end solvent management service means you are able to cut the number of people and suppliers you need to deal with.

A partner helping you bring about your environmental transition
As specialists in the circular economy, we develop many solutions to minimize the environmental impact and carbon emissions of your projects in order to combat climate change. We fully understand the energy impact of distillation, which is why we recover the waste heat, minimize heat loss by using effective insulation and control the amount of electricity we use.
