The 2020 Call For Code Global Challenge by IBM India is calling on developers across the globe to find technological solutions to halt and reverse the impact of climate change. Nature inFocus supports their endeavour.


The current pandemic has made us all realise how reliant we are on technology. As we all learn to manoeuvre and adapt our professional, personal and social lives within the confines of our homes, we find technology coming to our aid – when we need the right information, in sourcing essential supplies, coordinating community action, and staying connected with our extended families. But even outside these four walls, entrepreneurs and organisations are working on using the right technological tools to solve some of the world's most pressing issues. 

Increasingly, technology is being leveraged to address the climate crisis that we all experience in various ways. 2019 was the seventh-warmest year in India since 1901, and the country witnessed unprecedented floods across its various states. There is no debating that the time to act on the climate crisis is now.

To encourage technological innovation for some of the world's most pressing issues, IBM has launched Call For Code, a challenge for developers across the globe. The Call For Code submission portal opened on March 20th, and the contest will remain open till July 31st, 2020. The Global Challenge is accepting ideas under two tracks – COVID-19 and Climate Change, with relevant subcategories for each. The Global Challenge winners will be announced in October 2020. Winners will be awarded $200,000, receive open source support from The Linux Foundation, and will get a chance to meet mentors and investors. Above all, the winners will see their solutions deployed through Code and Response, exemplifying how good tech can make a difference.

To extend our support for the initiative, we are featuring some organisations and entrepreneurs who are already working towards implementing climate change solutions. Whether it is making clean energy more affordable, providing appropriate solutions for waste management, raising awareness about issues like food waste or repurposing waste into useful materials, technology has been at the forefront of these actions and innovations. Just like them, if you are interested in exploring the intersection of climate change and technology and coming up with real-world solutions to mitigate or reverse the effects of the crisis, IBM’s Call For Code challenge is for you. Participate in this global challenge and share your vision for a better future. For more information, visit Call For Code.


Graviky Labs

Paint the air clean

Staying indoors has definitely made us all more aware of the world around us. Have you also noticed clearer skies and cleaner air? What if this could be a permanent fixture in our lives, and not just the outcome of a pandemic? At least, that is what startups like Graviky Labs are working towards.

Founded in 2016, the startup is finding ways to upcycle carbon-rich emissions and converting it into products like ink/coating, rubber and construction materials. Graviky has developed a proprietary recycling technique to turn zero-value carbon emissions into high-value materials which are now being used by various industries. The technology can handle emissions from different grades of carbon, such as industrial and automotive-based emissions. The first upcycled line of products that they have come up with is called AIR-INK; a grade of inks and coatings that have been used by artists and printing, packaging and fashion industries across the globe, to create awareness about the environment.

Banka BioLoo

Leading India's toilet revolution

In 2012, we did a national launch of bio-digester toilets in villages in Odisha. It was a big hit, and people started thinking about human waste management after this. I learnt so much working on this project. It really opened my eyes to the issue of open defecation. I met rural women who were begging for toilets, and I thought to myself, is this something that people should be asking for, to begin with? That is when I started focusing on the rural areas and talking about these issues in larger platforms. The first challenge was to provide toilets, and now our focus is on treating and disposing the waste effectively. The thing is, these problems require appropriate technological solutions, but they are also issues that need community involvement. It has to be a balance.

A zero-waste world can be a reality only as a result of accountability. Accountability from governments, companies/brands and most importantly from ourselves. There is so much that we can do in our individual capacities – compost, buy less, use less plastic, reduce take-outs, use sustainable menstrual products, ask questions about waste and circularity to the brands that we love, are just some examples.

No Food Waste

Eradicating food waste with technology

Did you know that about a third of the food produced globally goes to waste? In India, a major contributor to food waste are large events like weddings or public gatherings. The leftover food from such events is often dumped in landfills. This is also a waste of all the resources that went into growing and preparing the food. But organisations like No Food Waste are ensuring that this food gets redistributed among people who need it the most. 'Feed People. Not Landfills' is their motto. When informed about excess food at an event, the No Food Waste team reaches the location, inspects the food for quality, and redistributes it at their predetermined 'hunger hotspots' – locations that include slums, orphanages, and nursing homes. The initiative started in Coimbatore, Tamil Nadu, with the first distribution involving a single volunteer carrying surplus food from an event in two large shopper bags, transporting it in a bus. Today, they have dedicated transportation vehicles and vessels, and the mission has spread across cities like Chennai, Hyderabad, Salem, and Tirunelveli, to name a few. They have also developed the No Food Waste App to simplify the food recovery process.

When it comes to stopping food waste, it is a collective effort. Both volunteers and donors depend on reliable information, so food is recovered and distributed quickly. Our No Food Waste App was created to address this problem. When we launch a chapter in a new city, it’s easy for us to identify food sources – wedding halls and event centres. But to identify hunger hotspots, we rely on people in the city. They can mark these places using our app. Additionally, if there is enough food for about 10-20 people, they can find the nearest spot, and make the delivery themselves. In these difficult times of the coronavirus lockdown, the information gathered on hunger hotspots is aiding volunteers with food distribution. In Coimbatore we are working with the City Municipal Corporation and delivering food prepared in a centralised kitchen. Reliable information makes all the difference. We are currently working on updating the app, and a new version will be released next month.

– Balaji Narayanaswamy, Team member – No Food Waste

So far they have managed to salvage over 400 tonnes of food, feeding more than two million people. No Food Waste has received the Swachh Bharat Award for 'Best Innovative Practices' and the Commonwealth Youth Award, 2019, for the Asia Region.

When founders Shirish Phadtare and Dr Medha Tadpatrikar visited a wildlife sanctuary in 2009, they were told about a deer that was found dead with a lot of plastic content in its stomach. Shocked to learn that discarded plastic was responsible for this, the couple turned to their own kitchen to find ways to address plastic waste. They involved their pressure cooker for the initial set of experiments, and realised that plastic could be broken down to a poly fuel using the process of Thermo Catalytic Depolymerisation (TCD). Today, Rudra, along with Keshav Sita Memorial Foundation Trust, Pune, collects about 20-25 metric tonnes of discarded plastic waste, which is then processed in their facility in the city. The resulting fuel can be used in furnaces, kerosene stoves and as fuel for generators. The organisation also works with 52 villages around Pune city, providing the residents with fuel for their cooking needs. The residue generated after the depolymerisation of plastic can be used as material for building roads. The released gases are repurposed to generate energy for the depolymerisation itself. Learning about their methods, people have shipped plastic waste to them from other states as well. Rudra is the winner of the Excellence in Recycling Award, 2017 and has been featured by Discovery India.

GEM Enviro Management Pvt Ltd

Giving new life to packaging waste

While many businesses are interested in employing effective waste management measures, they often find the task daunting. What if someone could step in and help you through the process? Meet GEM Enviro Management. The organisation assists corporates in fulfilling their Extended Producer Responsibility (EPR) requirements, which mandates that producer companies effectively treat and dispose of post-consumer waste. GEM aids in the collection of pre and post-consumer packaging waste, which is then segregated and recycled. The treated waste is turned into products like T-shirts, bags, stationery and blankets, giving waste a new life. In collaboration with Ganesha Ecosphere, a PET recycling company, GEM converts packaging material to fibres that are then used in manufacturing these products. The company has also set up more than 100 Reverse Vending Machines (RVM) across different states in India. These machines make the collection of used PET bottles more efficient, reducing litter. The collected bottles are crushed within the machines and sent to the recycling facilities.

GEM Enviro Management endeavours to optimise the use of technology in the waste management sector in India. We believe that increased use of technology can bring several positive changes in this sector. Also, it will lead to improved work conditions for the people associated with waste collection. We developed the Reverse Vending Machines in-house, and we have also created mobile apps for the efficient collection of plastic bottle waste. We have seen an increase in waste collection because of these resources. This is the kind of impact that we are talking about.

– Sachin Sharma, Director – GEM Enviro Management Pvt Ltd

In 2019 alone, they have processed 100,000 tonnes of plastic waste. The organisation also works with municipal corporations to train waste collectors on the importance of segregation, for which they have been recognised by government agencies.
