Abstract: A method for recycling packaging wastes, referred to as first articles, made of PET or polyolefins (PO), that can be decolored in accordance with the “key-locker” principle, and second articles made of PET or PO, comprising the steps: (a) pre-sorting the first and second articles, (b) pre-washing the articles, (c) comminuting the articles to form flakes, (d) washing the articles, (e) dewatering and drying the flakes, (f) flake sorting, (g) extrusion, (h) solid-state polycondensation (SSP) in the case of PET wastes, or (i) decontamination in the case of PO wastes. The first articles are separated from the second articles by optical sorting and are decolored separate from the second articles in a decoloring step (j) by a reagent referred to as a “key.” The first decolored articles are temporarily stored (m) after step (j). After being stored, the first articles are fed to separate steps (g) and (h) or (i).

Abstract: Method for recycling trays and blisters made of PET, which are referred to as articles, comprising the following method steps: (a) pre-sorting the articles, (b) comminuting the articles to form flakes, (c) washing the articles in a first washing step, (d) dewatering the flakes, (e) drying the flakes, (f) sorting the flakes, (g) extrusion, and (h) solid-state polycondensation (SSP). The first washing step (c) is a gentle washing step with reduced particle friction and a low temperature below 62° C. During the sorting of the flakes (f), the flakes, which have been gently washed in the first washing step (c), are sorted.

Abstract: Process for deodorization of recycled polyolefin pellets (23) in three steps: In a first step, the moist pellets (23) are contacted with a circulating inert gas at a temperature between 110° C. and 160° C. in a steam stripper (11), and the steam is precipitated in a condensate trap (29). In a second step, the pellets (23) are sent to a vacuum silo (13) under negative pressure and contacted with a gas flowing in countercurrent. In a third step, after the vacuum silo (13) the pellets (23) are sent to a first heat exchanger (15) and contacted with the gas flowing in countercurrent from the second step.

Abstract: A computerized system for managing a parking lot includes: a beacon in one-way, or location sensor in two-way, communication with a smart device for locating the smart device without it having to determine its own location, a vehicle sensor for sensing the presence of a vehicle, and a computer-implemented server operable to determine from the beacon's identification or receive from the location sensor the location of the smart device. The server authorizes entry or exit of the vehicle when a smart device status indicates acceptance, and the smart device and the vehicle are both at a same appropriate location. The server updates the smart device status after a payment transaction. Entry or exit may be authorized by opening a barrier, displaying an authorization message, communicating a message to the smart device, and/or not issuing a non-authorization alert. The server may receive reservations, and may communicate lot occupancy to third-party systems.

Abstract: The invention relates to a method for producing polyolefin recyclates, in particular HDPE recyclates. In a specified sequence, color-mixed polyolefin-containing groups are washed at a low temperature, washed at an increased temperature in an alkaline medium, flake-sorted, and treated at an increased temperature in order to remove migration materials. By virtue of the aforementioned method, polyolefin recyclates can be obtained with a substantially improved degree of purity compared to hitherto commercially available recyclates, said recyclates being usable in the production of novel consumer product packaging. Additionally, unpleasant odors connected to known polyolefin recyclates due to the decomposition products of migration materials formed during the extrusion process are largely prevented.
