Turn Recycled Plastic into 3D Printing Filament

Sustainable Problem: Waste

As we’ve established, humans produce a lot of trash – apparently of the more than 300m tons of plastic produced globally every year, one refuse truck’s worth ends up in our waters, landfills and streets every minute.

Technology:

  • Reflow converts recyclable plastic into 3D printing filament using open source technology.
  • Reflow filament is made from recycled PET bottles collected in developing regions, and revenues from the filament go back to the waste collectors who gather these bottles, which the company claims can increase their income by up to 20 times.
  • The market for 3D printing filament – the majority of which is made from virgin plastic – is growing rapidly. A recent report predicted the 3D printing materials market will grow by nearly 266% in the next five years.
  • 3D printing seems to be offering the developing world is employment – there are an estimated 15 million people globally who currently make their living from waste picking

Stakeholders:

  • Reflow
  • Waste Collection Companies
  • Artists
  • Designers
  • Various Printing Companies

Deployment/Implementation:

  • set up a production facility at a local rubbish dump, where waste pickers convert high-density polyethylene (HPDE) – mostly used for plastic bottles – into 3D printing filament to eventually be sold to 3D printing companies.
  • Marketing campaign
  • Introduce into different societies at different levels due to so many variations

Comments to greentechsmartcities: It is fascinating what some people can do with garbage and plastic waste. The art collective Luzinterruptus has a history of tackling political and social issues in Europe. The “Labyrinth of Plastic Waste” is but one example. “We were looking to demonstrate, in a poetic manner, the amount of plastic waste that is consumed daily,” Luzinterruptus explained in a statement. “In addition to focusing attention on the big business of bottling water, which leads to very serious problems in developing countries, whose citizens have watched as their aquifers have been privatized with impunity for the exclusive enrichment of large business owners and ruling classes without scruples.”

Sensor-Packed Pedestrian Crossing

Crossing1Crossing2

Sustainable Problem: Civic Engagement, Safety

Sensor-packed pedestrian crossing is fit for a modern city

Technology:

  • A prototype LED crossing uses sensors to respond to the movement of vehicles, cyclists and pedestrians
  • “We’ve been designing a pedestrian crossing for the 21st century,” says Usman Haque, Umbrellium‘s founding partner. “Crossings that you know were designed in the 1950s, when there was a different type of city and interaction.”
  • This smart crossing doesn’t just look more modern than the 60 years old versions; it uses machine learning to make the crossings safer. Figures from the Transport Research Laboratory show that 7,000 incidents happen on them each year in the UK.
  • The actual crossing doesn’t exist until it’s safe for you to cross – then LED patterns appear to direct people and stop cars.
  • The machines could also learn to project the crossing at a slightly different orientation if, for instance, everyone makes a beeline for a certain shop after a school days.

Stakeholders:

  • Umbrellium
  • Insurance Firm – Direct Line
  • Cities

Deployment/Implementation:

  • The project is still some way from completion.
  • To speed up the process, the code behind it is being made open source.
  • Deploy when figure logistics of implementation are figured out
  • Have multiple detection systems, to be fail safe such as version that has a pressure sensor which detects where footsteps are.

Comments to: World’s First and Largest Vacuum Air Cleaner #BT2443

The results confirm that the tower captures and removes up to 70% of the ingested PM10 and up to 50% of the ingested PM2.5. For a tower in an open field in calm weather, this provides PM10 reductions up to 45% and PM2.5 reductions up to 25% in a circle with diameter of more than 20 m around the tower. When the tower is applied in semi-enclosed or enclosed courtyards, the beneficial effects can be much larger. These statistics are astounding to me and these towers can help many people in very polluted areas.

Beta.ray – Spherical Collector That Combines Photovoltaic and Thermal Power

beta-ray-generator

Problem:

  • Solar panels are generally fixed and their optimal collection is limited due to collection angle.
  • Cloudy days traditional solar panels are inefficient in collecting sunlight
  • Solar panels take up a large amount of space.

Solution:

  • Most solar panels are fixed direction, the beta.ray can rotate according to the sun direction, maintaining optimal collection angle – the small sphere, 75% smaller than a panel that collects the same amount of energy.
  • Cloudy days the beta.ray can improve efficiency by 50% due to concentration of sunlight.
  • The beta.ray is small and can be placed on any flat surface.
  • The spherical shape of the solar collector, together with an integrated solar tracking system, cover far smaller surface area than solar panels of equal efficiency, and allow a collection of energy, even if the light is very low
  • The transparent crystal lens that works as a concentrator of incoming light, Rawlemon’s design promises as much as 95% more energy conversion

Article: http://www.alternative-energy-news.info/spherical-sun-power-generator/

Stakeholder:

  • Rawlemon (company)
  • Home owner
  • Building owner
  • Energy companies
  • Green energy policy advocates

Deployment steps:

  • Certification in EU / US / Asia
  • Supply chain (manufacturing partners)
  • Retail distribution (commercial / retail)

Water and Pollution in the Textile Dyeing Industry

parsons-airdye-7

Problem: Water Usage and Pollution Caused by Dyeing Textiles

Textile dyeing is estimated to cause 17-20% of the global industrial water pollution. Until recently, little attention was given to the environmentally harmful effects of the dyeing process, when it comes to chemicals, waste, and water usage.

Technology: 10 Awesome Innovations Changing the Future of Fashion” by Melissa Breyer

  • A new technology, AirDye developed in California by Colorep, works with proprietary dyes to transfer color with heat from paper to fabric in a one-step process.
  • Basically, it has created a software that “computes color recipes that reproduces the specified color reflectance curve on a target substrate”.
  • This process has the potential to save between 7 and 75 gallons of water in the dying of a pound of fabric. It can save energy and produces no harmful chemical by-products.
  • Furthermore, the technology uses 85 percent less energy than traditional dying methods.

Stakeholders:

  • AirDye tech engineers/designers
  • Colorep engineers
  • Technological partners
  • Investors
  • Fashion designers
  • Clothing retailers

Implementation:

  • In order to implement this technology on a large-scale, a number of investors need to be introduced
  • Fashion designers must begin to use the technology to introduce the innovation to the public and encourage its usage down the supply chain i.e. factories and low-end designers/retailers.  For example, AirDye has become a vital component to the designers Costello Tagliapietra and Gretchen Jones and was used for their Fall 2012 collection
  • Governments in countries that manufacture dyed textiles should subsidize this technology to consumers (factories and managers who buy it) so that it can bring down the price, encourage product development, establish familiarity of the product, ensure future customers and therefore be more easily implemented in the thousands of dyeing factories around the world.
