And, where possible, manufacturers should “down-gauge” materials (make parts thinner). Government legislation can be enacted to support such measures, as well as to require plastics manufacturers to get involved in the disposal of plastic items – a responsibility long imposed on packaged-goods manufacturers in Europe.
此外，产业界应该为可循环利用材料寻找新的应用，同时最小化新材料的使用。在可能的条件下，制造商应该“向下加料”（即把部件做得更薄）。政府立法应该支持这些措施，并要求塑料制造商参与塑料制品的处置——在欧洲，这一责任长期以来被强加给了包装品制造商。
