Sustainability Problem: Reducing plastic waste is a dilemma. It is something that most consumers want to do but find it hard to do so. That is because plastic is readily available, cheap, convenient and durable. Now, an Indonesian-based startup has come up with a delicious and nutritious solution to help reduce our dependence on this environmental hazard.
Using seaweed as raw material, Evoware was able to come up with an eco-solution for problems concerning plastic waste. Evoware’s bioplastic products are eco-friendly, biodegradable and even edible and healthy for human beings. This will not just impact the environment but also for the livelihood of Indonesia’s seaweed farmers. Some benefits of bioplastics:
Food that works as flexible packaging
Has the same function as plastic packaging, plus it dissolves in warm water & is biodegradable
Shelf life: 2 years, without preservatives
Contains high fiber, vitamins and minerals
Maintains shore cleanliness
Improve seaweed farmer’s wellbeing and income

“A very innovative technology indeed. Again, such ideas will always stumble upon large cost and scalability. And the fact that it needs a carbon-neutral plant to build upon means that it still needs further research since many power plants around the world are still not carbon-neutral.”
2) Sustainability Problem: Solid Waste and GHG Emissions Reductions
Solid waste contains a lot of potential yet only 2% of it is currently used to generate energy and 17 million metric tonnes of non-recycled garbage are produced every week. Moreover, the continued use of gasoline is adding CO2 to the atmosphere and exacerbating greenhouse gas emissions. Currently, there are 400 ppm of CO2 in the atmosphere and without quick and concrete action, there will be no chance to mitigate the effects of climate change. In order to address this issue, the adaption of biofuels will be essential for many sectors including automobiles, oil and gas, and agriculture, however, converting to biofuels from fossil fuels will decrease dependence on foreign suppliers, decrease GHG emissions, and reduce overall costs.
2) Sustainable Technology: Gasification of Waste to create Ethanol and Methanol
Enerkem, a company located in Canada, is converting garbage into biofuels through gasificiaton. This technological process converts unrecoverable (non-recyclable and non-compostable) waste into syngas which is made up of carbon monoxide and hydrogen. Syngas is clean, sustainable, and can be produced at a low-cost. Syngas can be used to replace fossil fuels, liquid fuel, and liquid crude oil as it can be transformed into green diesel fuel. Enerkem “transforms the syngas into “cellulosic ethanol” and methanol, which can be used to create a clean-burning fuel. Gasoline with ethanol has more oxygen, which helps it combust more completely, thus reducing emissions.” Enerkem just opened the first commercial-scale gasification plant in Edmonton, Alberta and they plan to keep increasing production of advanced forms of biofuel which can replace gasoline.
3) Technology Stakeholders
Locate medium-sized city where trash is such a problem that exporting of waste is a necessity.
Using the City of Edmonton model, convince local officials and city agencies that the creation of an Enerkem plant will be beneficial.
Raise Capital to create the plant
Initiate Construction while hiring human capital
On-site Testing and Implementation

Single use plastic bags are among the greatest contributors to land and water pollution. They are normally used for just minutes, but take can take up to 1,000 years to decompose, polluting land, air and water, and killing wildlife in the process.
Avani Eco, an Indonesia based company, has created a 100% plant based, non-toxic and biodegradable material that can replace plastic bags.
The material is made primarily from the cassava root, a very common and inexpensive vegetable in Indonesia.
The material is harmless to animals and humans if ingested, and breaks down in months.
The bio-based plastic bags still cost about twice as much as conventional plastic bags.
Stakeholders for this technology include municipal governments/sanitation departments, large retail stores and supermarkets (who are increasingly facing plastic bag bans), as well as environmental advocacy groups and non-profit organizations dedicated to waste and pollution reduction.
The first steps for deploying this technology on a large scale:
Invest in R&D to help reduce the cost of the bio-based plastic bags, making them more competitive with traditional plastic bags.
Ban the use of single use plastic bags in local municipalities
Partner with a large national retailer (such as Walmart, Target, or Wholefoods to gain widespread recognition and prove market viability.
Comment on post “Smart Transportation & Smart Waste Management” by sn2754:
While I think technology is a great idea for optimizing waste management, there would be a huge hurdle to implement this in NYC, as commercial waste (from stores, offices, restaurants, etc.) is not managed by the city. Each business has a contract with a private waste hauling company, which causes garbage routes to be extremely inefficient and redundant. In order to implement a “smarter” waste management system as described in the post, legislation would first have to change the status quo in commercial waste contracts.

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.
The cold chain refers to the temperature-controlled part of a supply chain that involves a series of interrupted refrigeration, storage and distribution processes. Often, a departure from the prescribed temperature range can result in spoilage and can cost businesses and society immensely. Two prime examples of the sustainability challenges associated with cold chains are as follows-
The losses associated with cold chains in the pharmaceutical industry are estimated at $ 35 Billion in 2014. This involves spoilage of medicines that could have been delivered on time to mitigate healthcare costs to society
Spoilage of consumables and food, including shrinkage due to expired products. It is estimated that if the current levels of food loss and wastage are maintained, food production will need to increase by 70% in developing countries alone, which requires significant investments (~$83 Billion a year). There is also the risk of increasing pressure on limited resources and increasing GHG emissions associated with expanding agricultural activities
Mitigating losses in cold chains can save society billions of dollars in healthcare and nutrition investments.
Sustainability technology- IoT to manage cold chains (IMS Evolve, Tagbox)
The Internet of Things refers to the interconnected nature of physical and electronic devices in order to create a network that can collect and exchange data in real time. We have already seen examples of smart refrigerators that can pair up with your favourite voice-enabled assistant to inform you about your shopping list. Using this technology at an industrial scale can help prevent severe cold chain losses
Sensors connected throughout the cold chain can monitor temperature and relay information back in real time to supply chain managers. Mobile and web-based applications and dashboards can crunch the real-time data and provide visualizations on the health of products and need for any interventions
Integrating these devices with a mobile based application will facilitate easy monitoring- managers can simply monitor the data and signals on a mobile app and receive warnings in time to take corrective action.
Two examples of IoT solutions that address cold chain efficiency are IMS-Evolve and Tagbox.
From the perspective of retail stores, the following stakeholders need to be engaged to scale this solution.
Store operations and management teams
Merchandising team- buyers, range and space managers etc.
Supply chain logistics
Given the potential to improve pharmaceutical cold chains as well, the following stakeholders need to be engaged-
Supply chain logistics
Pharmacy retail store operations and management
Stakeholder workshops and discussions to educate store managers, supply chain operators etc. on the use of SaaS platforms, sensors and data visualization interpretation
Identify test locations and build out required infrastructure (sensors). Define success criteria and set up experimental framework, conduct a pre-post analysis and scale up deployment to more stores based on learning from the pilot phase
Enter into long term partnerships with technology service providers in order to create an incentive for service providers to channel capital and continue to innovate
Set up grant projects for using this technology in developing nations- it provides an incentive to continue to innovate and scale these technologies at low cost
Sustainability Problem: Waste is a recurring problem that has persisted through decades of innovation towards unnatural manufacturing and processes. Delving deeper, plastic waste is a big issue because they do not degrade easily. It can take hundreds of years for plastic to break down. With an estimated worldwide consumption of 1 trillion plastic bags every year, a better solution is needed.
AVANI Bio-Cassava Bag could be the solution:
100% biodegradable, compostable and disposable – degrades within 90 days
Made from cassava starch and all-natural resins, 100% renewable – contains no conventional plastic
Safe for consumption – dissolves in lukewarm water
While the EPA estimates that the textile recycling industry recycles approximately 3.8 billion pounds of post-consumer textile waste (PCTW) each year, this only accounts for approximately 15% of all PCTW, leaving 85% in our landfills.
Decomposing clothing releases methane, a harmful greenhouse gas and a significant contributor to global warming. There are dyes and chemicals in fabric and other components of clothing and shoes that can leach into the soil, contaminating both surface and groundwater.
2. Technology solution: Worn Again
Worn Again has been developing chemical recycling for over three years and through trials and lab experiments they are perfecting a process where solvents are used to selectively dissolve different types of textiles, recapturing them as a raw material, which can be used to make new clothes, thus being reintroduced into the supply chain as new. Within the Textile Sorting Project Worn Again is dedicated to achieving the shared goal of creating circular supply chains for textiles through collaboration and new technologies.
The tests for this new technology, which will be monitored by H&M and Puma, are built around separating and extracting polyester and cotton from blended fiber clothing. Another task will be to separate dyes and other particles from polyester and cellulose, which has always been a challenge when recycling. The raw materials that are recaptured can then be used to spin new fabric for clothes. This circular process will have an extremely positive effect on bringing down the need for virgin resources and as such reduces carbon emissions, as well as the use of toxic pesticides, chemical fertilizers or exhaustion of land for growing crops.
Worn Again isn’t the first to develop a textile-to-textile technology. In 2014, Swedish scientists developed a process to recycle cotton by shredding clothes to pulp and turning the substance into threads of viscose. The company responsible for making the pulp is now preparing its first fabric-recycling factory and teaming up with several entrepreneurs in the textile industry.

The subsidizing companies (H&M, Puma)
Local governments / NGOs to foster usage of this product
The team is currently engaged in full time development of a circular recycling technology for the textile and clothing industry, working closely with its’ development partners, H&M and Kering Group’s Sports & Lifestyle brand Puma.
H&M and Puma have enough infrastructure to deploy the product worldwide with a strong marketing campaign. However, costs should be mitigated in order to make the products accessible and the process economically viable.
Consequently, support from NGOs and local governments is key to allow tax reduction on recycled clothing and recycling plant set-up in order to lower costs as present them as feasible alternatives.
