7.6 Guidelines


number, e. g. only cleaned or disassembled and reassembled as components of new products19. For some consumer goods recycling is enabled by refilling some of its parts, typically the primary packaging. In the end, it is important, as has been repeated many times, to consider and estimate the global impact, measured against the fact that cleaning and transportation also have an impact. Guidelines for facilitating re-use: • Increase the resistance of easily damaged and expendable components (Example 7.18) • Arrange and facilitate access to and removal of retrievable components • Design modular and replaceable components (Examples 7.19) • Design components according to standards to facilitate substitution • Design reusable auxiliary parts (Examples 7.20) • Design refillable and re-usable packaging (Examples 7.21) • Design products for secondary use (Example 7.22)

Examples 7.18 One of the most common examples of re-use is the repeated use of glass bottles, which are re-collected and washed. The bottom perimeter of the bottle can be reinforced to reduce the risk of breakage due to various contacts and small occasional inevitable collisions. The transportation and cleaning activities of course have their impact, but here re-use is nevertheless expedient. 7.19.1 Rank Xerox photocopiers are disassembled after their eventual disposal, and the components go through examinations to test their eligibility for being used in new photocopiers. The photocopiers of mixed components correspond to the same quality as new photocopiers, because of the test requirements that have to be surpassed. In this system about three-quarters of the components are re-used.
