Imagine walking around the island of Bali and seeing pristine beaches, clean waterways and roads lined with trees and plants rather than piles of rubbish and debris. Not only did Melati and Isabel imagine this, they decided to make it a reality.
Bye Bye Plastic Bags founders and team in 2014
In 2014, sisters Melati and Isabel Wijsen were students in Grades 6 and 7 at Green School Bali. They came up with the idea of Bye Bye Plastic Bags to organize petitions, awareness-raising campaigns and massive beach clean-ups. Swimming in the seas just off her childhood beach, Melati recalls emerging from the ocean with a plastic bag wrapped around her arm. Determined to change things, they went on to start the biggest “Children Driven Action” campaign the island – if not the country – has ever seen. Collecting hundreds of thousands of signatures on a petition to free Bali of single use plastic bags, their advocacy efforts finally bore fruit in 2018, when the Bali government banned all single-use plastics.
The idea for the campaign, recalls Melati, came from a lesson at school, “If we are the future of Bali and the world, we have to start thinking about how we can become like our role models now.” It is the belief instilled in all students at Green School; that they are changemakers – not just of the future, but NOW.
The sisters have taken their mission to ban single-use plastics worldwide, the NGO is now active in 29 countries. Their Mountain Mamas project trains local women in Bali to hand-make reusable bags from donated or recycled materials. Last year, Melati co-chaired the final session of the World Economic Forum’s Sustainable Development Impact Summit in New York. She also recently launched a second charity – called Youthtopia – aimed at inspiring other young change-makers to pursue their goals.
The Forbes recognition, “proving you’re never too young to achieve real success” is a beautiful one, and builds on the foundation that Green School Bali seeks to lay for its students in their formative years, on being changemakers of today. Educating for sustainability and nurturing green leaders is our route to making the world sustainable, and Melati and Isabel are a beautiful manifestation of how that is possible.

We currently enrol nearly 300 students (ages 6-18 years old) from the villages surrounding Green School in ‘Ageg’, our extra-curricular English Language programme, meaning ‘Sustainability’ in Balinese. Students deliver 5 kilograms of sorted recyclable waste per semester: ‘Trash for Class’ in exchange for their classes. The recycled waste is delivered to Green School’s Kembali Recycling Facility.
A major focus of our community work is focused on sustainability learning and this is embedded in all aspects of the Kul Kul Connection programme. Find out more about Green School’s sustainability initiatives here. Our KKC Student Council is comprised of “Connectors” who involve themselves with Green School initiatives and raise awareness about these activities in their local community.

4. Particular talent or track-record in campaigning and activism
5. Applicants must be Indonesian citizens
6. Demonstration of financial need
Scholarship Impact
– Started in 2008/09 with 18 scholars enrolled – 19.5% of total enrollments
– 40 Indonesian students educated in 8 years
– 5 Scholars graduated
– 5 were accepted at University
“This is about the Indonesian kids. Many of the scholarship kids came to the trash walk the other morning and it was really uplifting to me to see how these kids are creating a green future for Bali. The whole thing is about creating green leaders for this island.” John Hardy, Green School Co-Founder

The Bio Bus story represents the nexus of solution based learning, community engagement, and enterprise. Bio Bus is a social enterprise, initiated by Green School students, that strives to provide sustainable transport services to Green School students and community members. The project sponsors setup a cooking oil collection system in the local community. Once cooking oil is collected, it is sent to a processing facility to create the biofuel that is then used by the Bio Bus vehicles to transport students and community members.
The Bio Bus project has resulted in multiple learning opportunities and practical sustainability solutions. The decrease in passenger car trips resulted in carbon emissions reductions, as well as the ecological benefits of recycling cooking oil and using the biofuel as a fuel alternative. As well, a byproduct of the cooking oil recycling process is glycerine which can be further processed into sustainable soap products.
The use of bio soap reduces the use of monoculture palm oil based products that have chemical additives which pollute fresh water sources, not to mention the massive ecological impact of palm oil plantation related deforestation. This is one of many inspiring Green School projects.
A friend just told me about Green School’s TED Talk
The thematic class in the morning is my favourite and this month we are doing ‘Settlers’. We break into teams and each team pretends to be it’s own country. We are learning about history, migration, politics, trade, community and team-work. Each team makes their own shelters near where the school pigs are and we trade useful items, skills and food with the other countries. It’s fun and muddy!
I run with my friends down to our classroom and we kick our shoes off before going up the stairs to our classroom. I think it’s special to have a classroom that looks like a giant bamboo treehouse.
Riding on the BioBus with my friends is fun. I heard it runs with french fried oil.
For breakfast, I like a smoothie and toast with jam. We buy the jam from school, it’s rosella flavour and its sweet and tangy – yum.
I wake up just after the sun comes up and put on my favourite shorts and t-shirt. They’re old and comfortable, which is good, because we are going to get muddy today!
At Green School we are constantly seeking solutions to meet our needs that minimize embodied energy. The energy embodied in process water contributes to climate change. Our solution to this challenge was to install a Reverse Osmosis (RO) water filtration system to meet our drinking water consumption needs. The source of our facility potable water is a 60 meter deep well. Although the well water is drinkable, we decided to install a Reverse Osmosis Biofiltration System to ensure the purity and safety of the drinking water for our community.
A simple definition of aquaponics is that it is the integration of aquaculture (raising fish) and hydroponics (the soil-less growing of plants) that grows fish and plants together in one closed system.
The fish waste provides an organic food source for the growing plants and the plants provide a natural filter for the water the fish live in. The third component of the system is the microbes (nitrifying bacteria) and composting red worms that thrive in the growing media. They do the job of converting the ammonia from the fish waste first into nitrites, then into nitrates and the solids into vermicompost that that are food for the plants.
Green School uses composting as one of its solid waste management strategies. We have a dedicated Compost Station on campus where biomass, kitchen waste and cow manure is collected and composed to create an organic material that is used as nutrient rich fertilizer for the permaculture gardens dispersed throughout the school grounds that supply our kitchen.
The Compost Station is a excellent place to learn from and connect with natural processes. To see the layers of a composting pile is to watch life itself in motion. The alternating green nitrogen and brown carbon layers are composed of every variety of waste; wood chips, brown leaves, green leaves, grass, food scraps, and manure.
As the valuable organic material starts to decompose a dark, rich, productive soil amendment that gardeners call Black Gold begins to evolve. If you push your hand into the pile you can feel the heat the process generates.
The Green School solid waste management system is one of the greatest examples of our systems thinking culture. Our waste is part of a closed system and understanding how to cycle it back through the environment and into our soil and food creates an authentic sense of connection to all the moving parts in our natural world. We are striving to create a closed loop system from the food forest and the gardens, to the kitchen, out to the composting pile and the grey water management system, back to our lunch plates and finally back to the composting toilet for yet another cycle.
We have four primary solid waste streams that we need to manage at Green School:
This is consistent with the principles of a circular economy where there is no such thing as waste and a movement away from the destructive practices of the “Take, Make, Waste” system of industrial production and consumption that plagues contemporary society.
The microhydro vortex embodies the learning by doing philosophy. In 2005, Green School launched this exciting renewable energy project with a vision and aspiration to be a carbon positive school in a carbon positive community. Through this project we have learned invaluable lessons in microhydro energy development, community engagement, and ecosystem services benefits. It is estimated that when the Vortex is commissioned sometime in 2016, that it will supply approximately 6 kW of renewable energy to the overall Green School energy portfolio, getting us that much closer to our goal of being a carbon positive school within a carbon positive community.
Solar energy is an important and material component of Green School’s renewable energy and carbon emissions reduction strategy. In 2011, Akuo Energy generously donated a solar PV and microgrid energy management system to Green School. The solar PV energy system is composed of 118 solar PV panels, a 72 kWh capacity lead acid battery bank, and inverters. Current PV panel optimum capacity contributes 21 kWh to Green School’s renewable energy portfolio. Under the current renewable energy strategy, we plan to expand the the solar PV share of the energy portfolio mix to meet Green School’s energy needs and get us closer to our goal of being a carbon positive member of a carbon positive community.
