Green School Weekly News

When grade 12 gathered to talk about a project designed to leave their legacy behind after graduating from Green School, two projects fell into place: the Earth Garden and the Bio Bus. Here we will report on the latter and share its story.

During the Jalan Jalan Wednesdays, grade 12 gathered to discuss creative ways in which they could propose to change an element of Green School that had not yet reached its sustainable potential. Issues that quickly came up included our produce, our green policy and inevitably our transportation system.

Presently we are responsible for producing nearly 200 tones of carbon dioxide a year by our current transportation system. The Bio Bus is an initiative for greener transportation in that it will reduce our carbon emissions by 75% if we were to cut the number of vehicles and run the minimum amount of vehicles on biodiesel. Middle school has done tremendous work by surveying and documenting our transportation flow. Here are our prospects:

Without Lengis Hijau, the only biodiesel plant in Bali with whom we are collaborating, our efforts wouldn’t have reached so far. Pak Magnus, a Green School parent and prominent team member was able to reach out to the biodiesel plant and schedule a class trip. The director of Lengis Hijau, Pak Endra Setyawan, was keen in supporting our venture and has since been processing the used oil we collect combined with their collection into biodiesel. “Yayasan Lengis Hijau will always give Green School their best support and services to enable the project to run well, inspiring other people to use Biodiesel for their cars and engines” – Pak Endra Setyawan. For a quick look at the process:

This is our own used oil collection from Ibu Kadek’s kitchen


The process the collected oil goes through at the biodiesel plant, where unhealthy waste gets separated into glycerol and biodiesel through transesterfication separation.

The team is calling out to the community in search of individuals and businesses ready to support this initiative by contributing to the collection of used cooking oil. The establishment of community collecting systems benefits the island and it’s locals as there is no systematic waste disposal system for cooking oil. It is either filled into canisters and disposed of together with solid waste, dumped into waste water or finds its way to middlemen in the black market.

In the black market waste oil is superficially cleaned and sold to small kitchens once again. This entails substantial health risks, especially for the urban poor. Although many hotels officially refuse this practice, it is often put up with due to the lack of alternatives. In addition to this health threat, the disposal of used cooking oil in such an unsustainable manner also results in the pollution of water bodies, freshwater resources and soil. Please be aware that Green School’s Kembali is the drop off point for used cooking oil and that all amounts are greatly appreciated (for further enquiries please contact

Furthermore, Adam and Cazmir attended the Earth Day Conference Lengis Hijau hosted to represent Green School’s Bio Bus in the handing over of a certificate of appreciation by the governor of Bali. In a few weeks the team will proudly be present at the United Nations REDD+ Sustainable Solutions: From the Ground Up conference held at Green School, which will be reported on then!


So far, the Bio Bus has successfully completed its first week of commute to and from Green School and Ubud. Above is a picture of the maiden voyage. The feedback of the teachers and their kids has been encouraging, as one of the first commuters put it, “This is a SLICK way to commute to Green School” – Pak Kyle. So be sure to sign up for the first 5 seats available to students and parents next week over at the Shanti House, schedules & prices will be posted next!

Ini adalah kisah dibalik berjalannya program Bio Bus di Green School. Berawal dari kelas jalan-jalan Rabu, siswa kelas 12 berkumpul dan bertukar ide tentang program keberlanjutan. Mengacu pada banyaknya emisi gas karbondiaoksida di alam, maka ide untuk membuat transportasi yang lebih hijau muncul.

Ide kami ternyata sejalan dengan apa yang pabrik Lengis Hijau kerjakan. Lengis hijau adalah pabrik yang mengolah minyak bekas pakai menjadi biodiesel. Minyak didapatkan dari minyak bekas pakai rumah tangga dan industri.

Bekerjasama dengan Lengis Hijau, Transportasi Bus Green School kini menggunakan minyak daur ulang. Bus ini telah beroperasi selama seminggu dan mendapatkan respon positif di kalangan guru dan siswa Green School. Sehingga, di kesempatan selanjutnya, kami menyediakan kursi untuk komunitas Green School yang lebih luas dalam menggunakan transportasi ini.
