Water ATM – Primal Sarjaval

Screen Shot 2016-08-04 at 1.32.27 PM

Sustainability problem:

Slum areas in developing countries  lack access to networked, let alone potable water. Many rely on informal water vendors (from pushcarts or trucks) and bad quality surface water.Such water would require further cooking, which means extra cost and effort. These sources of water are also not available 24/7. This can have high toll on monetary and health costs, affecting citizen and municipalities.

Sustainable technology.

Water ATM (Primal Sarjaval operator) is a fully automated potable water dispensing machine. A GPS is installed in the machine so its quality can be remotely maintained. The ATM is fully automated and can dispense water 24/7 since it does not have to be attended, unlike truck and pushcart vendors which requires residents to wait. Residents pay using a card recharged by a mobile phone or at the vending kiosk.   The machine charges per use and does not have a high upfront cost for citizens.

Stakeholders

  • Slum dwellers
  • Health and water municipalities
  • Health advocates
  • Private companies that manages and distribute the machine

Implementation

  • Companies championing the ATM need to partner with health NGOs to promote this product more extensively to the municipalities for its widespread implementation.
  • Survey data of water provision and waterborne diseases concentration to find out where to best implement the ATM.
  • A pilot project should be carried in a chosen area to get detailed feedback for a successful implementation later on.

Alternative outdoor cooking

Sustainable problem

The use of fossil fuel for cooking at home or in camping grounds is a growing concern for health and environmental reasons around the world. Moreover, open fires and fire pit construction are also frowned upon (at times prohibited) due to similar reasons. Demands have strongly arisen for a more sustainable alternative.

 

Sustainable technology

 

The BioLite basecamp allows people to use found wood (smaller pieces of wood e.g. branches) as fuel. This is due to the product’s design which allows efficient use of heat. A diffusion layer of the stove particularly helps to spread heat evenly across the grill area. The BioLite Basecamp has been said to produce 94% less smoke than traditional stoves, addressing health concerns.

 

While being used to cook/grill, the BioLite also has a charging station for gadgets that uses the exact same energy source. The grill is also completed with a battery to store electricity for later use.

 

Stakeholders

  • BioLite company
  • Investors
  • Environmental/ health concerned costumers
  • Environmental/health NGOs

 

 

Deploying technology

  • Biolite needs to partner with environmental NGOs to promote their product more extensively worldwide (especially in regions where there is still high use of fossil fuel for cooking).
  • Environmental NGOs should try to pressure distributors for this healthier alternative. Environmentally concerned costumers who are familiar with BioLite may be able to help champion this product.
  • BioLite need to network with new investors and maintain good relationship with existing investors to accumulate funding for research to constantly improve the technology. A particular aspect the product can work on is perhaps reducing its weight/bulk which will be tricky but can be unique value point to the product. Research to try and reduce the production price will also be definitely helpful.

Hypoallergenic recycled carpet!

Sustainability challenge:Screen Shot 2016-07-06 at 1.27.10 PM.png

Carpets can be a pain to people with breathing sensitivity, allergies and asthma. There is also a demand in the market for interior composed of sustainable materials (whether recycled, or has less carbon footprint in its production).

Additionally, more people are staying indoors for a lengthy period of time. Many entities are constantly looking at new strategies to make this unavoidable lifestyle healthier.

Technology:
The Desso AirMaster carpet takes in and retains pollutant and fine dust particles (which can later be removed with a vacuum cleaner), thus creating a healthier indoor climate.

The engineered product provides a mechanical solution without the use of chemical additives – giving a permanent solution without side effects. This carpet is designed to be made partially with recycled carpets. It has been tested by asthma and allergy organizations that stated the carpet to be better at allergy prevention in comparison to hardwood flooring.

Stakeholders

  • Desso company
  • Offices
  • Homeowners
  • Health related NGOS
    Green construction companies

 

Steps to deploy

  • Desso should network and brainstorm with green construction companies to find out specific market demands and thus tailor their products in that direction to have a wider catchment of consumers.
  • Desso should work together with health related NGOs to research how to constantly improve the positive impact of their product to indoor health.
  • Desso should network with important stakeholders such as office and homeowners and advertise the benefit of their products, which not many people know of. Health related NGOs can play a large part in lobbying efforts

Toys from plant-based plastic by Bioserie

Sustainability problem

bioplastics

Most toys are made from fossil-fuel based plastics. There is uncertainty whether such products can have negative health effects on babies and children. Styrenes, phthalate, BPA and PVC are well known health offenders. Some of these substances can become hormone disruptors that are linked too reproductive and birth problems as well as carcinogens. Toys that are advertised as “BPA-Free”, “PVC-Free” etc, can still contain petrochemicals harmful to health. Additionally, there is an increasing interest and demand for lower carbon footprint products.

Bioserie toys provide an innovative answer for those who search for aesthetically pleasing products while maintaining their children and the environment’s health.

Technology

  • Bioserie is the world’s first to produce its toys from purely plant based plastics and materials. It uses a blend of polylactic acids without petrochemical additives. Their product is certified by the Department of Agriculture’s BioPreferred program to be 100% bio-based.
  • Modifiers are used to ensure the product to be non brittle and heat resistant. The company has focused its R&D on improved resistance and durability.
  • The coloring material are also based on sustainable raw materials specially developed for biopolymers. It Meets global industry and composting standards.

 

Stakeholders

  • Costumers (Most likely parents)
  • Toy stores/ distributors
  • Investors
  • The company
  • Environmental & health NGOs

 

Implementation

  • Bioserie and NGOs should market to parents the dangers of oil based toys and promote the comparative benefits of plant based plastic toys.
  • NGOs should pressure toy stores and toy distributors to supply more products made out of safer materials such as Bioserie’s plant-based plastic.
  • Bioserie should manage their relation networks of potential investors in order to gain more capital to further enhance the quality, design and marketing of their product.

Green-mix concrete as a sustainable alternative building material

greenmixconc

Sustainability problem

Production of concrete is environmentally destructive. In its 1 metric ton manufacture, up to 920 KG of CO2 is produced. The 3 billion metric tons of concrete made around the world in 2009 alone accounts for 5% or CO2 emission produced that year. Efforts to develop a sustainable alternative is thereby crucial.

 

Technological solution

(This post will review the green-mix concrete design developed by researchers from Universiti Teknologi MARA Malaysia)

 

  • The concrete is manufactured and designed utilizing conventional materials with partial replacement using recycled materials namely:
    • Fly ash – byproduct of coal power plants that are usually disposed in ponds and sent to landfills. Its properties have a large potential of replacing cement.
    • Crushed concretes from demolished construction – used as aggregates.
    • Aluminum cans – used as reinforcements. They can easily be changed to chopped fibers.
  • The concrete is cost effective due to the optimized material proportion. Its strength is also enhanced by 30% and is environmentally better performing as raw material consumption and landfill waste are reduced.

 

Stakeholders

  • Municipalities
  • Environmental NGOs
  • Construction companies
  • Green concrete manufacturer
  • Building users

 

Implementation

  • Government should create incentives for the production of the green-mix concretes or buildings that have opted to utilize them. This can be done through tax breaks, subsidies etc. NGOs may be able to help efforts lobby the government for such efforts.
  • Maintain relationship with investors to secure funding in order to constantly improve the quality of the product.
  • The university should create a marketing strategy to promote the green concrete mix, not only to construction companies and building designers, but also for potential commercialization in the nearby future.

Small Scale Waste-To-Energy (WTE)

Sustainability problem

Landfill sites in cities are filling up quickly. The quantity of waste is ever-growing with the increase of population, industrial and commercial activities. Energy prices are on the other hand going skyward. Many regions have additionally begun introducing ambitious renewable energy targets.Technologies to deal with waste that have by-products of energy, hence, are highly sought after.  The currently dominant waste-to-energy (WTE) technology is operated at a large scale. Images  of mass incinerators exerting gasses from large chimneys and traffic from convoys of wagons transporting waste does little to the industry’s reputation with the prevalent Not-In-My-Backyard (NIMBY) attitude.

Picture2

Areas of sustainability

Waste, Energy, Pollution, Health.

Technology

Small-scale WTE plants tend to occupy 4 acres, in contrast to the average 20 acres required by mass burn incinerators. They are more affordable, have low profile construction and minimal emissions. They can thus be more easily integrated and presents a sustainable solution.  Although technological operators have varying small-scale WTE plant designs, the simplified explanation below will use that of ENERGOS ASA’s (a company based in Norway):

Picture1

(1) Fuel preparation process – municipal waste is pre-treated through shredding and magnetically separating recyclable ferrous material.

(2) Thermal conversion process (from waste to energy) – First, fuel enters the primary chamber where it is gasified and syngas is created. Second, the syngas is transported to the secondary chamber for high temperature oxidation.

(3) Steam generation – Hot flue gas from the secondary chamber then gets recovered in the Heat Recovery Steam Generator, which consists of a smoke-tube boiler, water-tube boiler and economizer. The boiler system can be designated to deliver saturated steam (for heat) or superheat (for electricity production).

The system comes with a dry flue-gas cleaning system where lime and activated carbon are injected downstream from the economizer, separating ash from flue gas hence controlling air pollution. 

Stakeholders

Municipalities, Citizens, Technology Operators, Environmental NGOs, Investors

Deployment

  • Municipalities need to be lobbied for the installation of small-scale WTE plants.They need to be exposed to successful implementation case studies.  NGOs may play a large part in providing assistance for such lobbying efforts.
  • Local communities in areas with potential installation of small-scale WTE plants need to be educated regarding its benefits (especially in comparison to the larger scale WTEs) in order to change their perspective.
  • Proponents of the technology needs to network and maintain good relations with investors in order to derive more funds for research and development to refine the existing small-scale WTE technologies.
  • As the technology can be useful not only by municipalities but also companies with large production of waste, governments should also provide market incentives.
  • Technology owners are expected to come up with financing options for municipalities that are interested in applying the technology.
