While it is essential for fashion brands to reuse and recycle clothes, their efforts will not significantly reduce their carbon footprint in the long run because the rate of clothing production and consumption is only going to accelerate. Sustainable fashion ultimately means less fashion, which contradicts fashion’s current linear “take, make, and waste” model. This project helps fashion brands achieve on-demand production by supplying color-changing fibers to be spun into garments, minimizing the risk of overproduction. At the retail store, shoppers will be the ones to customize the color of their garments at the color-changing stations. Viberent’s technology has the potential to redefine the 3 R’s: Reduce textile and dye waste, Reuse clothes in a completely new way, and use Recycled material to create color-changing fibers. Let’s close the loop and transform linear fashion into circular fashion.
Track: Climate, Energy & Sustainability
Wise Earthcare
Over 1.2 billion plastic toothbrushes are thrown away in the United States every year–enough to fill up 1,100 shipping containers. The problem is that 99% of those toothbrushes are made from plastic that is non-recyclable and they end up in landfills or the ocean, contributing to the increase of pollution. The solution is a toothbrush that is 100% biodegradable, clinically validated by the American Dental Association, which is delivered directly to the consumer via subscription, retail, and dental offices. These products will be both clinically effective and sustainable and will include an array of oral care products, including toothbrushes for adults and kids, electric toothbrush replacement heads, floss, floss picks, toothpaste, and mouthwash. With validation from the ADA and both dentists and consumers regarding the design, this product can ensure that patients/users are receiving the best possible oral healthcare products, while still playing a positive role in the sustainability movement.
HelioVap
Across the 2,700 islands of Indonesia, one in eight households lack clean water access. Traditional desalination technologies have too high energy requirements, costs, and brine discharges to be implemented in these coastal communities. As a result, households often purchase bottled water, which is both expensive and environmentally damaging. HelioVap is a floating, stand-alone desalination device that can provide reliable water access to coastal communities through an off-grid, zero-liquid discharge process that directly uses sunlight to separate seawater into its fundamental components. HelioVap is being designed to produce 75 L of water per day, which should be sufficient to meet the drinking and cooking requirements of five households through the utilization of alternative energy sources including sunlight, wind, and natural temperature gradients. This technology does not threaten biodiversity in the coastal ecosystems that over 50% of the population relies on for income, and the use of alternative energy sources reduces cost and carbon emissions of the process.
DissolvBio
Billions of pounds of polyethylene are produced each year, and unfortunately this compound can take thousands of years to break down. Polyethylene has also been linked to human cancers, groundwater toxification, and environmental damage. A reliable means of breaking down polyethylene is necessary and would have a huge impact. Unfortunately, microbial degradation of polyethylene is not common in nature. Polyethylene has been around for less than 100 years and enzyme evolution takes millennia, so microbes have not had enough time to develop this ability. However, recent techniques in Directed Evolution allow researchers to take evolution into the lab and speed it up to thousands of times its natural rate. This project proposes to apply Directed Evolution techniques to a specific enzyme tied to polyethylene degradation in order to create a novel enzyme capable of degrading polyethylene efficiently and reducing global plastic waste.
The Berkeley-India Stove Project
Improving Women’s Lives with Improved Cookstoves in Rural India
The ultimate goal of the Berkeley India Stove (BIS) Project is to deliver the BIS into the hands of the poorest 830 million people in India suffering from exposure to indoor air pollution due to their daily use of inefficient biomass cookstoves. An essential component of the project is to ensure the sustained adoption and long-term usage of the BIS, which reduces smoke emissions and fuelwood consumption by as much as 50% compared to traditional Indian stoves. The BIS is one of the best available cookstoves in the Indian market considering a performance to price ratio. Bolstered by strong partnerships on the ground and a comprehensive business plan, including innovative strategies for dissemination and monitoring, the BIS has the potential to dramatically curtail the harmful impacts of this critical environmental, health, and socioeconomic issue caused by inefficient stoves.
Wet Technik
Wet Technik is a student startup founded at Makerere University looking at reducing the costs of water usage and environmental pollution by hazardous wastewater through the use of constructed wetlands. The team is comprised of three students from a multi-disciplinary background with a shared passion for solving the ever-present problem around wastewater handling and to bring to light the potential of its recycling. Through using a mixture of waste bottle caps and pumice in the constructed wetland, Wet Technik has proven that it will reduce the area requirements, making this system even more accessible to factories, schools and eventually households. The constructed wetland is already the cheapest and easiest way to maintain a system to recycle grey water making it very attractive to people in Uganda.
RePurpose Energy
According to the Solar Energy Industries Association, solar’s long-term success “depends on the cost-effective integration of energy storage”. Already, excess solar power is often wasted, and California is only a third of the way to its 100% clean energy target. Achievement of this bold goal will require energy storage at scale to harness solar power after sunset. Meanwhile, California will have 5 million electric vehicles on its roads by 2030. Recycling their batteries is expensive, but reuse is economical; over 75% of an EV battery’s original capacity typically remains at the end of its useful life in a vehicle. RePurpose Energy tests, reassembles, and redeploys used electric vehicle batteries to provide commercial solar developers with energy storage solutions at half the cost of new battery alternatives, so they can offer more electricity bill savings, and California can accomplish its clean energy goals.
Solanga
Solanga builds solar powered community centers, or Solanga Hubs, in areas that lack electricity. The Hubs provide people valuable services at affordable prices – such as cell phone charging stations, computers, televisions, well-lit study or social gathering spaces in the evening and electric water pumps. These services are sold on a per-use basis. The Hubs are 3rd party financed. Solanga’s business model lowers the cost of critical services to individuals by scaling and centralizing the energy system for the community at large. Social centers where people exchange goods, services and ideas are of utmost importance but are harder to create in the developing world due to the absence of well-lit spaces. Solanga Hubs solves this problem and also reduces CO2 emissions by minimizing the need for dirty kerosene lanterns and diesel generators. Solanga is the WeWork + Internet Cafe + library of the developing world.
EMPOWER
The rise in home solar generation is reducing emissions from the residential building sector. However, net energy metering (NEM) policies are being phased out in many states, making residential solar projects less attractive from a financial standpoint. EMPOWER is addressing this problem through the development of a modular, affordable, residential energy management system that leverages the predictive power of modern machine learning to simultaneously optimize local energy generation, storage, and flexible loads within a house or microgrid. It integrates weather, photovoltaic, and user behavior forecasts to increase efficiency and is retrofittable to existing homes. In areas without NEM policies, EMPOWER estimates savings of over $500/yr for a product with a target price of $200-300.
