Gaau1Up collaborates with an architectural designer, Matthew Hung. As a fabricator for the exhibition, our role is to materialize his ideas by working on the wooden structure and plastic shingles. All 400+ shingles were made from polypropylene (PP), no. 5 plastic. <b>Collecting Plastic</b> We collected the transparent PP from different Waste No Mall stations around Hong Kong. Waste No Mall is a citizen-initiated movement, demonstrating how “Community Resource Recycling and Sharing Center” is running and proposing the reformation of current Refuse Collecting Station. Embracing the idea, we contacted them, sorted out and collected transparent PP from citizens’ waste. <b> Mould</b> The moulds we used were made by laser-cut stainless steel (sls), separated into top, middle and bottom piece. 2mm sls board was used as the middle piece as for the shape of shingles; and 3mm sls board were used as the top and bottom piece for compression. <b> Re-moulding Plastic</b> We made a shelf by slotted angles bar and put in the oven so we can heat up 4-5 moulds at the same time. The moulds were heated at 250°C for 15-20 mins. After that, 170g of transparent PP flakes were put into the mould and heated at 250°C for another 20 mins. While heating, the moulds were not closed yet. Then, we took out the mould and compressed them with reinforce frame and metal clamps, to compress the moulds evenly. After that the moulds were cold-downed in water or under air. <b>Installation</b> After the cut off of lake out, we installed the 400+ shingles onto the wooden frame by two self-tapping screw. The shingles were overlapped by half of their length to prevent water ran into the architecture. _______________________________________________________________ Facebook of Waste No Mall: https://www.facebook.com/WasteNoMall/ Facebook of Gaau1 up: https://www.facebook.com/gaau1up/ Instagram of Gaau1 up: @gaau1up
