Area : Waste, Energy

Description:

75% of tires are made of petroleum (needed for the production of the rubber used). At the end of the products’ life most of them end up in landfills .

Michelin, thanks to a new concept, 3D printed a new kind of tire. The tires are made out of molasse (sugar paste), then turned into ethanol which is used to produce rubber replacing petroleum. Since the tire is only made of natural sources (molasse, bamboo,…), the tire is fully biodegradable.  Although, thanks to the new design of the tires, their useful life should be greatly extended. Indeed, instead of changing tires when a problem arises, the new Vision tire can be modified with a 3D printer.

Stakeholders: Car manufacturers / City officials / Car owners

Implementation:

  • Michelin needs to research markets to find countries/ citis which are early adopters of new technologies;
  • They need to contact the government of this country/city to run some test in the city and have approval of their technology being used
  • They need to find car manufacturers that are also early adopters to pilot their technology

Other article comment: The tiles are also gathering data that can be used for better understanding pedestrians habits and crowd flows . This type of information is useful to commerces but also for cities.

Turn Recycled Plastic into 3D Printing Filament

alexandravamanuLeave a comment

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.”

Plastic Reuse for Practical Use

Dominic Bell5 Comments

1) Waste & Civic Engagement: 

Plastics and other waste are discarded in developed countries where every convenient because little value is seen in them after they have served their purpose. This causes pollution of the oceans, streets filled with waste, and little social change. The Hamilton Perkins Collection has come up with a way to work with developing countries to convert plastic waste around the world into valuable products by adding value.

2) Technology:

  • Canvas is made out of recycled bottles and recycled vinyl billboards to produce bags
  • The plastics are recovered from Haiti by community members in developing countries and recycling centers clean and crush the plastic
  • The business estimates that compared to normal duffel bags, 15,000 pounds of CO2 is saved in emissions

3) Stakeholders:

  • Residents in developing countries
  • Retail Businesses
  • Customers valuing causes

4) Deployment: 

  • Generate pipelines for gathering plastics
  • Partner with other developing countries to increase scale of production
  • Partner with store front businesses to diversify the market

5) Student Post:

“The roads are made from plastic soda bottles which allows the DOT in Texas so save almost $700,000 in traditional repair. With this model they found a way to save money in repairs and also take plastics out of landfills.”

Just when you thought it couldn’t get better… HomeBioGas 2.0

omriklag3 Comments

The Problem

Sustainability issue – waste, food waste.

We generate about 1.3B tons of food waste annually, almost all of which ends up in landfills where it decomposes and release methane. Nonetheless, this “waste” contains a lot of nutrients that can be used as fertilizers and the released methane can be captured and used. Many municipalities are trying to implement composting programs but their reach is currently quite limited and the vast majority of the population still does not have access to an institutionalized compost program… so what can you do??

The solution

ca44a4332d17a600f00de4bc1c71eaa9_original

An easy to use home compost system!

  • HomeBioGas is an Israeli company specializes in residential, outdoors, low maintenance, compost systems.
  • HomeBioGas 2.0 is based on two holding tanks, one for the waste digestion, which is filled with water containing bacteria, and one for the gas generated.
  • The system also produces liquid fertilizer as a by product of the process.
  • The system can take up to 6 liters of food waste a day, and (at full capacity) generate enough gas daily to power a traditional stove for up to 3 hours.
  • The system is very heat sensitive and does not function properly when the surrounding temperature falls under 20˚ (68F) for a long period of time.

Stakeholders

Two key stakeholders are:

  • Families and individuals that use gas powered equipment and live in areas where the climate allows for outdoor, unheated composting.
  • Off-grid Communities in developing countries

Implementation

Step 1 – Successfully fund their Kickstarter campaign.

Step 2 – Continue to develop the technology so that it can work in a wide variety of climates, especially in environments that have cold winter such as New York.

Step 3 – Start a new campaign for HomeBioGas 3.0 (when it will become available) while simultaneously reaching out to relevant communities and stakeholders for pilot studies and contracts.

Comment on  Smart Urban Growth Tackles Mobility and Electricity Distribution Concurrently:

“Intersting post!
I would add a note about Better Place, as someone who lived 10 minutes form their HQ and witnessed their almost-rise and fall: Better Place’s plan was to first set up a charging infrastructure throughout Israel and only once they reached a sufficient quantity and reach of charging stations, then they would begin to really push their family-oriented EV model. They encountered a series of setbacks and constant delays, yet decided to release their EV when there is no adequate infrastructure to support it, which at the end (in my opinion) led to their failure.
Also, I visited their HQ and showroom about a two years before they ceased operations and at the time they were still not on schedule for the deployment (and perhaps even large scale feasibility) of the battery changing stations.”

Comments to Off grid solar powered water device – Zero Mass Water by JV2610

  • A unit with one solar panel, the company says, can produce two to five liters of liquid a day, which is stored in a 30-liter reservoir that adds calcium and magnesium for health and taste. This seems very energy efficient and seems to be able to store a pretty good amount. The addition of electrolytes is even more interesting and beneficial for health.

Longer Lasting Produce!

lcblake043 Comments

FruitBrite

  1. Sustainability Issue (Waste):

Over 30% of produce harvested is never consumed and every year, almost $30 billion worth, or 25 billion pounds, of fruits and vegetables are wasted. This happens even though there are about 42 million people who don’t have enough to eat in just the U.S. alone. Wasted produce also means that all the time, energy, money, and water put into cultivating it is also wasted. However, it is hard to avoid this problem because there are so many steps between the growth and consumption of produce.

Berrybrite

  1. Summary of Technology (Hazel Technologies):
  • FruitBrite and BerryBrite are essentially biodegradable and non-toxic packaging inserts that fit into fruit containers and emit ingredients to keep produce from spoiling without having to spray on any additional chemicals
  • The inserts allow the produce to last longer, which also means that the produce can have a greater range of area where they can be transported to and sold in before spoiling
  • FruitBrite is a time-release sachet that contains an ethylene blocker (ethylene is the gas given off by some fruits that speed up the ripening process)
  • FruitBrite can extend produce’s lifespan by 2-3 weeks and has been tested on various produces including apples, asparagus, broccoli, cherries, tomatoes, etc.
  • BerryBrite delivers controlled dose of a blend of natural essential oils that inhibit the growth of bacteria, fungi, and molds in berries
  • BerryBrite extends the shelf life of berries by up to 3x, reduces disease and rot by up to 90%, and improves post-harvest firmness by up to 2x

Sources:

 

  1. Stakeholders 
  •  Farmers
  • Supermarkets
  • Produce transportation companies
  • End consumers

 

  1. Next Steps
  • Work with large farms to incorporate FruitBrite and BerryBrite into their packaging product that can be used to store fruit and produce after picking
  • After driving adoption by farmers, introduce to supermarkets to be used for backroom storage
  • Once adopted by both farmers and supermarkets, introduce to transport companies as a way to provide farm to store consistency in packaging and storage

A Building itself can be a power plant by waste-generated tech

ly24271 Comment

1: Sustainability Problem

Area of sustainability category: Waste

Wherever you find humans, you find ‘waste’. And humans never run out of waste.  In the future, the majority of humans will live in megacities if we do not take any effective action to deal with the waste. To solve this problem, we should try to answer these questions that could we find a better way to handle the waste? Can we make waste decentralized and have it back at the building level so that nothing’s moving off-site?

2: Technology

  • SEaB energy offers a closed-loop system that essentially turns a neighborhood or business into its own power plant
  • SEaB makes waste decentralized and have it back at the building level so that nothing’s moving off-site
  • SEaB energy provides solutions that can eliminate a large amount of what would otherwise be thrown or flushed away and instead use the decomposition process to produce biogas that is converted into electricity

3: Stakeholders

  • Housing development
  • commercial stores such as supermarkets, restaurants which promise to generate a certain huge amount of waste every day
  • Government which aims to build a green, smart and sustainable cities

4: Process of implementation

  • Improve the technology to reach 100% energy re-production
  • publish reports on environmental-consciousness media to show the efficiency of this technology and arise the professionals’ interests
  • Attend the real estate conference to promote this technology

Comment on “Smart Yarn”: https://makeasmartcity.com/2017/10/09/smart-yarn/

In the article, it also mentioned that the yarn could also incorporate with a Bluetooth transmitter critical information and transmit the information to the headquarter instantly. With the development of technology, we may expect more advanced IoTs added into this smart fabric.
