Zero Waste Production in Small and Medium Industrial Cluster Collaboration project between Chalmers University of Technology Sweden and Gadjah Mada
University Indonesia in Mondialogo Engineering Award 2009
By: Muhammad Mufti Azis (Chalmers Students for Sustainability (CSS) Sweden)
Background
Sustainability has emerged as a global issue as UNESCO declared this decade (2005-2014) as United
Nations Decade of Education for Sustainable Development. For this purpose it is obvious that global
partnership, for instance between developed and developing countries, is needed to achieve
sustainability. My recent project exemplifies how developed countries could play important role to
rear developing countries to achieve sustainable development.
It goes far to a small village called Samigaluh which situated on the slope of Menoreh Mountain,
Yogyakarta, Indonesia where local people still depends on agriculture produces to support the
livelihood. Fortunately, from the land of this small village grows various plants i.e. cloves, patchouli,
vanillin, tea, cocoa, herbal and woods which later arises as a local potential to drive the local economic
wheel. Essential oil distillation has grown as a prominent home industry in Samigaluh village.
Unfortunately, essential oil production is only performed during dry season for the sake of high yield.
Therefore, local villagers contacted academia from Gadjah Mada University to help them solving this
problem.

Integration Concept
Given the situation in Samigaluh village eventually it was concluded that it is interesting to integrate
essential oil industry with tofu home industry (pabrik tahu) and animal husbandry i.e cows and goats.
Why Tofu and cows? Tofu is a primary meal and highly consumed by people in Indonesia. Therefore,
its production will have economic value and furthermore to suffice protein supply for villagers. In
addition, raw material to produce tofu i.e. soybean is not difficult to find in Samigaluh and the left
over (unprocessed soya) is useful to feed cows.
Cows and goats husbandry is carried out in a pen house which later produces meat and dairy products.
Interestingly, cow/goat dung is transferred into a biodigester mixed with liquid waste from tofu factory
producing biogas. The biogas is not only used to produce steam for essential oil industries but also for
tofu production and household usage. The waste from essential oil industry in form of condensed
water (warm water) is sent to local fish pond to support fish production. Therefore this concept is so
called “Zero Waste Production”. Figure 2 will show the grand design of the concept.

Mondialogo Engineering Award 2009
It was an initiative from Daimler and UNESCO to establish an award called Mondialogo (this year
2009 is the third round, please check for detail: www.mondialogo.org)). The theme of the proposed
project should be in line with UN Millennium Development Goal and the interesting thing is the team
should be a collaboration team between developed and developing country. It is so fortunate that my
colleagues from CSS are so enthusiastic to work together with students from Gadjah Mada University

to accomplish this project. Sweden has grown as one of leading country in biogas production and has
put a lot of concern regarding Sustainable Development issue. Therefore, it would be interesting to
invite Swedish colleagues to get involved in this project and also it would be important for them to
implement sustainability idea into real practice in such a developing country, Indonesia. Likewise,
students from Gadjah Mada University could learn many things from their partners and help out
villagers to develop the Zero Waste Production concept.
The team members from Chalmers are Marcus Högberg, Linus Helming, Martin Persson,Johan Toren
and myself. All of us are still member of CSS and have been working together in Sustainability issue
since 2007. It is so fortunate that we had received an official support from Chalmers Vice President,
John Holmberg, to participate in this competition. Likewise, our partner from Gadjah Mada
University (which consists of Annisa Utami, Annisa Sekar Palupi, Benny Chan and Awqi Gibran)
continually update the recent information from the site to us and ready to work together in an
international atmosphere.

Despite of the reality that we are facebook and youtube generation, it doesn’t mean we can’t do
anything for our single earth. Instead, it’s time for students to act together to create sustainable world.
At least this is the message from last S3 WSCSD conference in Regina Canada. It was so impressive
and memorizing that I could meet so many WSCSD colleagues from all over the world. Last but not
least, I do hope my current activity may inspire all WSCSD colleagues and feel free to contact us if
you have any suggestions.
