BOPI 12 BR/2023 REPERTOIRE NUMERIQUE 40 of alkaline nature based on the organic material contained in the waste. The solid waste treatment plant comprises a waste feeder consisting of a chute (1) arranged in at least two screw spirals rotating independently in opposite directions, the chute (1) being provided with technical means (2), for feeding the processed material and technical means for feeding reagent (3) and is also equipped with an outlet (1.2.) connected to the housing of the hopper (5), in which a vertically oriented.

(57) The injection-blow-moulding mould comprises: a punch (1) having a blow opening (3) connected to a first conduit (5) which is in communication with a first source of pressurised gas supply (6) configured to supply pressurised gas through the blow opening (3) at an overpressure (OP) above a blowing pressure (BP) suitable to blow a preform (30a) into a container (30b) and an exhaust opening (4) connected to a second conduit (7) which is in communication with a pressure-limiting device set at the blowing pressure (BP); a blowmoulding cavity (2) configured to receive therein the punch (1) with a hot and soft preform (30a) arranged thereon; and a cooling device associated to the blow-moulding cavity (2). Gas inside the container (30b) exceeding the blowing pressure (BP) is allowed to escape through the exhaust opening (4) thereby a cooling gas stream is created from the blow opening (3) to the exhaust opening.
