In addition to contributing to the safety of drivers by improving de-icing salts and abrasives used on the roads, natural brine also has environmental virtues since its use in pre-wetting chlorides and other abrasives enables to significantly reduce the application rate of these products. Junex aims to reduce the environmental impact of all its activities, therefore the company is participating in different projects to evaluate natural brine’s effectiveness in collaboration with scientific research centers. Junex is also evaluating the possibility of using its natural brine deposit as a geological reservoir for carbon dioxide storage.
In order to properly assess the effectiveness of its natural brine for the maintenance of unpaved roads in Québec’s context, Junex took part in a 5 year research project directed by the Civil Engineering Department of the Université Laval, in collaboration with the Canadian Council of Research on Natural Sciences and Engineering and many contributors from the road sector (Béton Québec, Transport Québec, FP Innovation, Holcim, etc.). The main objective of this research project (CARRLO) is to develop and validate adapted and economic solutions in order to conceive, rehabilitate or maintain performing, lasting, safe and comfortable driving surfaces in a Nordic Canadian context and to implement these solutions in a model which will be accessible to all managers of non-paved roads in Québec (municipalities, government institutions, contractors, etc.).

Doctoral degree project, Université Laval
One of the important missions Junex pursues is its contribution to the development of its areas of operation through training of competent, responsible people who are promoters of change and through promotion and sharing of knowledge.
This is why Junex is committed to finance a research project lead by a student registered in a Civil Engineering doctorate program at the Université Laval. The main goal of this doctorate work is the development of an Expert Dynamic Simulation Model for unpaved roads stabilized or treated with dust control agents. This is an extension of the CARRLO research project in which Junex is participating. The objective of this project is to provide computational tools to predict the reduction of the deterioration of a treated road compared to an untreated road. An economical study will be carried out with the help of a complete data base and will enable to calculate all costs related to the maintenance of an unpaved road. This economical study will provide concrete results concerning the savings caused by the dust control agent’s treatment and the stabilization of an unpaved road and savings will be compared. This expert dynamic simulation model will incorporate the results of experimental and economical studies in order to foresee gained profits for an industry or municipality following the use of a dust control agent’s treatment or stabilization.
Natural Gas or Carbon Dioxyde Storage
While producing natural brine in Bécancour, Junex also pursues the main objective of developing underground natural gas or carbon dioxide storage units. Natural gas underground storage is a strategic tool of great importance for a gas distributor since it enables the storing of natural gas in periods of low demand and to re-inject it in the distribution pipeline during peak consumption. Such units are particularly useful in a region such as Québec, located at the other end of the Canadian natural gas transportation pipeline and who is subject to important differences in temperature during change of seasons.
In parallel to the natural gas storage project’s evaluation, natural brine production also enables to evaluate the potential of the geological reservoir at Bécancour as storage for carbon dioxide. To this end, Junex is working in collaboration with the IRNS Chair of Research on geological sequestration of carbon dioxide.
