Пример замкнутого подхода к экономике циркулярных материалов описан здесь. Представлен целый устойчивый цикл, в котором полуароматические полиэфиры на биологической основе разрабатываются путем полимеризации, деполимеризации, а затем повторно полимеризуются с незначительными изменениями их выходов или конечных свойств.
