<p>This research addresses the serious issue of plastic waste in the Pacific. Using Samoa as a case study, we hypothesise that distributed recycling combined with 3D printing offers an opportunity to re-purpose and add new value to this difficult waste stream. It is also an opportunity to engage diverse local communities in Samoa by combining notions of participatory design, maker-spaces and ‘wikis’ of parts with traditional Samoan social concepts such as ‘Fa’a Samoa’, or ‘the Samoan way’ and sense of community.  The project seeks to explore creative and innovative solutions to re-purposing plastic waste via a range of design research methods. Field work in Samoa has established the scope of the issue through interviews with different stakeholders such as Government, waste management businesses, the arts and crafts community and education. The field work has also helped identify potential product areas and collaborative partners. The different types of plastic in the waste stream have been identified and material experiments such as plastic shredding and filament extrusion are underway using low cost open source processing equipment to transform plastic waste into usable 3D printing filament. From this filament, potential 3D printed end products are explored through a hands-on researching by making process.  The experiments inform the design of workable, economically viable, socially empowering and sustainable scenarios for re-purposing and up-cycling plastic waste; printed in the form of useful and culturally meaningful 3D printed objects, artifacts and products.Applications range from creating greater awareness of the issue by way of tourism and the Samoan notion of ‘mea alofa’ or ‘gifting’, through to functional utensils and parts. It is an opportunity to expand Samoa’s traditional forms of craft into new self-sustaining communities, maker-spaces and small scale local industries. The outputs of the initial project are intended to provoke discussion and invite participation in the implementation of these different scenarios of production.</p>

<p>Plastic waste presents a real global challenge and a threat to health, environment and the global economy. While awareness of the devastating effects of plastic waste on the environment has increased, the production of plastic products is still on the rise. As a result, many countries do not prioritise waste plastic recycling or the export of plastic wastes to other countries for recycling. However, the products from recycled waste plastics are considered to be of low quality and uneconomical to produce on large scale, thus making individuals and corporations giving preference using plastics from virgin materials rather than producing products from recycled plastics. These is therefore a need to develop an effective process through the use of technology to upcycle plastic waste locally to produce products of higher value from waste plastic. The current research sought to investigate the potential of distributed upcycling to change the production and consumption of plastic products in future. To this end, the study sought to prepare high value design application for upcycling and investigated how they could be implemented through large-scale 3D printing in urban environments. To achieve this, the researcher collected plastic waste materials from Wellington in New Zealand to be used in the study experiments. The plastic waste materials were first cleaned, sorted and cut into small pieces using a granulator before being taken through thermal processes to dry them out and set the right temperatures to ensure consistency of the plastic waste extrusion before being taken through the extrusion process. 3D Printing was used to design and make various final products from the recycled plastic waste. Experimentation with different formulations of waste plastic led to production of a high-quality filament successfully achieving the study objectives. As such, upcycling plastic waste using 3D Printing technology provides a locally viable solution to making useful products in large scale as a model for future development.</p>

Construction projects are often challenged by tight budgets and limited time and resources. Contractors are, therefore, looking for ways to become competitive by improving efficiency and using cost-effective materials. Using three-dimensional (3D) printing for shaping materials to produce cost-effective construction elements is becoming a feasible option to make contractors more competitive locally and globally. The process capabilities for 3D printers and related devices have been tightened in recent years with the booming of 3D printing industries and applications. Contractors are attempting to improve production skills to satisfy firm specifications and standards, while attempting to have costs within competitive ranges. The aim of this research is to investigate and test the production process capability (Cp) of 3D printers using fused deposition modeling (FDM) to manufacture 3D printed parts made from plastic waste for use in the construction of buildings with different infill structures and internal designs to reduce cost. This was accomplished by calculating the actual requirement capabilities of the 3D printers under consideration. The production capabilities and requirements of FDM printers are first examined to develop instructions and assumptions to assist in deciphering the characteristics of the 3D printers that will be used. Possible applications in construction are then presented. As an essential outcome of this study, it was noticed that the 3D printed parts made from plastic waste using FDM printers are less expensive than using traditional lightweight non-load bearing concrete hollow masonry blocks, hourdi slab hollow bocks, and concrete face bricks.
