wood plastic composites as potential applications of recycled plastics of electronic waste and recycled particleboard
Journal of Cleaner Production, 2016Co-Authors: Philipp F Sommerhuber, Tianyi Wang, Andreas KrauseAbstract:Abstract Wood–plastic composites were injection-molded from recycled acrylonitrile–butadiene–styrene and polystyrene from post-consumer electronics in the interest of resource efficiency and Ecological Product Design. The wood content was raised in two steps from 0% to 30% and 60%. Reinforcement performance of recycled particleboard was compared to virgin Norway spruce. Styrene maleic anhydride copolymer was used as the coupling agent in the composites with a 60% wood proportion to investigate the influence on interfacial adhesion. The composites were characterized by using physical and mechanical standard testing methods. Results showed increased stiffness (flexural and tensile modulus of elasticity), water uptake and density with the incorporation of wood particles to the plastic matrices. Interestingly, strength (flexural and tensile) increased as well. Wood particles from Norway spruce exhibited reinforcement in terms of strength and stiffness. The same results were achieved with particleboard particles in terms of stiffness, but the strength of the composites was negatively affected. The coupling agent affected the strength properties beneficially, which was not observed for the stiffness of the composites. The presence of cadmium, chromium, copper, arsenic and lead in the recycled resources was found by an elementary analysis. This can be linked to color pigments in recycled plastics and insufficient separation processes of recycled wood particles for particleboard Production.

Ecological Product Design value and remanufacturing for green short life cycle Product with warranty dependent demand in supply chain
Mobile Adhoc and Sensor Systems, 2009Co-Authors: Chun-jen ChungAbstract:Due to environmental warming and consciousness, business globalization and shortened Product life-cycle, numerous attentions have been paid to ecology protection, resource saving and effective operations management. Green Product and Production processes Designs have significant influence on the environment and resource re-usage. The relevant EU regulations, such as WEEE, RoSH and EuP, have been encouraging the enteprises to have a friendly way to the earth and reduce the greenhouse effects by controlling the disposals and the gas emission. These green Product Design and remanufacturing efforts are investigated in the development of an integrated Production inventory model. A numerical example is presented to illustrate the theory.

ICCE - Jump-starting learning communities in the Philippines using available online tools: educational outcomes and student feedback
International Conference on Computers in Education 2002. Proceedings., 2002Co-Authors: M. RamirezAbstract:This paper describes the pioneering trials in using widely available and accessible online tools to build a course-based learning community in a higher education institution in the Philippines. A quasi-experiment was devised using two intact groups to determine cognitive learning outcomes for an online course on Ecological Product Design, and focus group discussions and survey questionnaires gathered student feedback on their online experiences. The study found that the achievement scores of the online and face-to-face students during both the pre-test and post-test examinations were not significantly different. In general, the online participants appreciated the convenience, flexibility, appropriate pace, and increased freedom and self-responsibility that the "new way to learn" afforded in their off-campus learning communities. In the end, this project was able to demonstrate that the online tools of information technology can be ingenuously harnessed to allow peers to study and work together in spite of separation and relatively simple resources.
