Combining Polymers For Dublin to effectively deal with its waste, it must innovate new uses for recycled materials. A team at Rutgers University in New Jersey has developed a new structural plastic made of recycled materials. By combining flexible plastic waste with stiff plastic waste, the team has created a plastic that is both stiff and strong, where before neither would be suitable for building materials. The reconstructed plastic is now widely used by large institutions, including the US military, to produce structural items like rail ties 65% POLYETHYLENE 35% POLYSTYRENE RECYCLED POLYMER and pilings. With a new railway planned through Dunsink, plastic qualities qualities qualities from the plant could be used to help construct the line. flexible plastic stiff material stiff material examples: examples: examples: In many ways, this new recycled plastic is emblematic of the Dun- milk jugs foam cups rail ties sink renewal project. Historically industry and residential zones detergent bottles plastic coat hangers pilings have been separated, as it was considered dangerous to mix the two. But as technology has advanced, it is now plausible to have the two occupy the same space. The recycling center reflects this notion. The façade becomes a combination of both perforated skin with louvers to shade. The two together create a skin that begins to blend the massive scale of the recycle center into the existing landscape.
