Abstract
The invention relates to: - a thermohardening material comprising (as percentages by weight): a) from 31 to 45% of a resin selected from maleic, orthophthalic, isophthalic or adipic-based polyesters, or from vinyl esters having a urethane or epoxy base, b) from 5 to 17% of cellulose fibres, c) from 15 to 22% of reinforcing fibres having high mechanical strength, d) from 12 to 24% of mineral fillers, and e) the remainder: anti-shrinking additives, catalysts, separating agents and the like, - a process for production of the aforesaid thermohardening material in which the solid parts are first mixed in a mixer and the liquid components are mixed in another mixer and the solid mixture obtained is subsequently impregnated with the liquid mixture obtained, - a process for the recycling of molded parts produced from the abovementioned material comprising a first stage of combustion of the wastes and/or molded parts and a second stage of recovery of the combustion ashes.
