The rapid technical evolution of additive manufacturing (AM) enables a new path to a circular economy using distributed recycling and production. This concept of Distributed Recycling via Additive Manufacturing (DRAM) is related to the use of recycled materials by means of mechanical recycling process in the 3D printing process chain. This paper aims to examine the current advances on thermoplastic recycling processes via additive manufacturing technologies. After proposing a closed recycling global chain for DRAM, a systematic literature review including 92 papers from 2009 to 2019 was performed using the scopus, web of science and springer databases. This work examines main topics from six stages (recovery, preparation, compounding, feedstock, printing, quality) of the proposed DRAM chain. The results suggested that few works have been done for the recovery and preparation stages, while a great progress has already been done for the other stages in order to validate the technical feasibility, environmental impact, and economic viability. Potential research paths in the pre-treatment of recycled material at local level and printing chain phases were identified in order to connect the development of DRAM with the circular economy ambition at micro, meso and macro level. The development of each stage proposed using the open source approach is a relevant path to scale DRAM to reach the full technical potential as a centerpiece of the circular economy.
On despite its attractiveness, the complexity of this distributed approach represents a limit to this application. Moreover, the environmental and economical effectiveness still needs to be demonstrated. In this article, a conceptual model is developed and proposed for the collection process in a Closed Loop Supply Chain (CLSC) network of local and distributed plastic recycling in order to analyze its economic and environmental feasibility
We are a local plastic recycling facility that turns PET, HDPE, LDPE, PP, PS, PLA, PC and ABS plastics into re-usable, plastic intensive, and re-recyclable products. We support plastic free packaging, end engage in citizen science to understand the impacts of plastic on our environment.
Fab City Prototype: TOMORROW
After giving the group a general perspective on the spaces and people that are currently shaping the prototype, participants were invited to work on three particular subjects that are key to designing a roadmap for the future of the neighbourhood:
Fabrication & materials: with complementary production ecosystems happening inside the local network of Fab Labs, citizens have the possibility to produce what they consume, recirculating materials inside the neighbourhood and the city to reduce waste and carbon emissions associated with long-distance mass production and distribution chains.
Food production: growing food on the rooftops of Barcelona. Through urban agriculture practices, citizens can grow part of what they eat turning production of local clean food in a regular pat of their lives.
Energy: Renewable energy production. With the arrival of domestic batteries and the cost drop of solar technologies, citizens have the tools to produce part of their domestic energy consumption.
Our vision of Green Fablab (or Hackerspace, or Makespace) is that in these geographically distributed spaces, they can be considered not only as a fabrication spaces, but also a recycling, remanufacturing and refurbishing places in order to contribute to a more circular economy
Over the course of five days, local workshops, research centers, design agencies and local producers in the neighbourhood was connected into an ecosystem. Biologists, tech professionals, local makers, craftsmen, IKEA designers, and other trailblazers gathered in Barcelona for the project and collected wasted products from the streets of Poblenou in order to breath new life into materials that were heading to landfill.
The Fab City Global Initiative demonstrates our unique, multiscale way of working in the Full Stack Model . The Full Stack explains how the systems change from PITO to DIDO can be applied at the citizen, city and global level, enabled by shared values and physical infrastructure.
L’impression 3D, une technologie bonne qu’à fabriquer des Yoda moches et des gadgets inutiles ? Que nenni ! Réparer des objets en remplaçant une pièce défectueuse, réaliser des petit hacks de la vie quotidienne, concevoir des objets pratiques correspondant à ses besoins, c’est de l’ordre du possible pour toute personne fréquentant un fablab ou possédant une imprimante 3D.
An open resource for sourcing local manufacturing and materials
Make Works started because we wanted to make fabrication in Scotland more accessible for artists, designers and makers.
Now we teach passionate people in other places how to do the same!
O argumento mainstream clássico dos fablabs. Curioso que tem uma analogia dele mesmo - do MIT como mainframe -, que ele busca solução nos Fablabs pelo mundo. A minha solução é pensar a cidade como laboratório de fabricação, mas aí sou eu também repetindo a mim mesmo, ou quase.
Muito a retrucar sobre esse post e vídeo, mas eu estaria me repetindo. Vou internalizar para transformar em algo mais profundo, com tempo.
