N.B. Throughout our carreer, we have purposed to find, rather than simply seek out, results and solutions to scientific problems having direct or indirect bearings on practical problems.
Hereafter, we only mention those results that we feel are important to highlight the main stages of our scientific career.
In some instances, these results are the fruit of collaboration with other researchers.
- Proposal of a practical state equation for normal liquids, based on the cage model with potential function developed by Lennard-Jones and Devonshire. It’s an isothermal equation that is experimentally well verified in the case of real liquids, equivalent to that of Boyle-Mariotte for gases. Because of its simplicity, this equation would have its place in the curricula of basic science. With this equation, starting from a few simple quantities (coefficient of thermal expansion, of compressibility) measured at atmospheric pressure, we can calculate all thermodynamic functions of liquids under high pressures.
- Proposal of a unit mathematical formalism to address both proton and electron transfer reactions in an aqueous solution. Study of the electronic activity in aqueous solutions to characterize their redox properties. Equivalent theory to that of pH (proton activity) in aqueous solutions. Through this novel approach, we can undertake the study of incomplete redox systems (solutions containing only the reduced or oxidized form of a redox couple) and assess the true responsiveness of redox systems. This simple and fundamental theory has its place in the basic treaties on general chemistry, and even in the chemistry program of secondary education. The theory of the electronic activity of aqueous solutions, which introduces the concept of redox indifference next to that of acid-base neutrality, has interesting applications in fields as diverse as the study of the biocompatibility of drinking water, hydrometallurgy by bacterial action, sewage treatment, etc.
- Development of a geo-concrete construction material that does not require high temperature heating in its fabrication process (energy savings).
- Proposal of bioelectronic criteria for biocompatibility of drinking water. Whole-house rainwater harvesting system, including food and drink.
- Development of the EAUTARCIE system, water autarky for the home, supplied exclusively with rainwater without discharge of any pollution in natural waters, without the need for sewers and sanitation plants. The development of two commercial systems: PLUVALOR, or whole-house rainwater reuse and TRAISELECT, or the selective treatment of domestic wastewater. This led to the founding of two small Walloon businesses. Since then, these businesses have ceased operations, and the PLUVALOR and TRAISELECT systems are no longer commercialized.
- Proposal of a recycling method for human waste normally produced as domestic sewage. Simple and inexpensive technical solution. Development of a 3rd generation dry toilet – the biolitter toilet or BLT – which works on the principle that carbonaceous plant cellulose is used to inhibit the actions of urease and other enzymes in human excrement.
- Interactions between biomass management, water management and climate in an ecosystem (study in progress).
- Composting method to remediate soils that are polluted with heavy metals. Method that is used to control livestock manure pollution as well as rehabilitate gravely polluted industrial brownlands. Heavy metals are rendered biologically unavailable.
- Establishment of the concept of integrated «ecological» sanitation, a scientific and technical approach that fundamentally challenges the traditional concept of sanitation: instead of focusing on the best purification efficiency, it focuses on the least environmental impact by introducing the notion of environmental performance, by means of a full environmental life-cycle assessment.
Below, we only mention those publications of interest that may go beyond the field of top specialists. Throughout our career, we have prioritized the resolution of concrete practical problems rather than producing a large number of publications that would interest few specialists.
