Abstract: A device is described for the environmental reclamation of contaminated soils through the technology known as landfarming. According to the invention, such device provides one or more tubs (1) of a rigid material, (for example a metal material or a plastic material) each equipped with a sensing probe (3) of soil moisture to be inserted thereinto for reclamation, a watering unit (5), connected to said probe (3), and a collection point (4) of soil sample to allow analysis thereof. Preferably, the tub (1) has a bottom plane (2) tilted of 0.01% to 5%.

Abstract: A process is disclosed for the production of solvents and/or lubricants from renewable sources, comprising the steps of fat hydrolysis and an esterification reaction of the fatty acids with alcohols in the presence of zinc oxide. To the product of the fatty acid esterification reaction, a non-solvent is added, obtaining a precipitate that is separated from the product and used as a catalyst in the previous hydrolysis step of the fats used as a raw material.
In one embodiment, said process also provides an acidification step of waste soaps and surfactants.
In one embodiment, the precipitate used as a catalyst in the fat hydrolysis step can be used as a catalyst also in the fatty acid esterification reaction.-

Abstract: A process for the enhancement of the byproducts of a process for the regeneration of exhaust oils is described, wherein said process for the regeneration of exhaust oils which includes at least one of the following steps: a) passing of the oil to be regenerated into one or more centrifuges, b) storage of the oil, before treatment, in suitable containers, c) desiloxanation and d) filtering. The byproducts of one or more of steps a) to d) are treated, gathered and mixed with one another and added to the bitumen coming out as tail of a fractioned distillation step of the above-said regeneration process of exhaust oils.
A plant for the carrying out of a process according to any one of the preceding claims is also described, comprising a processing unit for each of the byproducts coming from steps a) to d) and a mixer (6) with stirring (7).-
