As part of its Blue Economy® campaign, non-profit organization ZERAP implemented a new, transferable and interdisciplinary project week on the subject “Energy Self-Sufficient Classroom” at the Lutheran School Berlin Center (ESBZ) in September 2012.
Enthusiastically, 14-year-old student Lydia explains the functional principle of the self-built “sewage” system in her classroom. “It cleans wastewater by conveying it through hoses and buckets with different deposits and plants into an aquarium before it is pumped up into the system again.” This technology is only one of many which the students of the comprehensive and integrative class comprising grades 7 to 9 built by themselves during the project week. The development of these technologies contribute to create an energy self-sufficient classroom.
The idea for the project resulted from a one-year cooperation with the school to renew the science teaching. The aim was to create structures which enable the students to find their own ways of gaining knowledge, develop competences and unfold their individual abilities. This is achieved by working independently, leaving room for experimenting and establishing experience-relations as well as by application of the methods Learning by Teaching and Learning by Engagement , given the fact that in science, everything is connected. Additionally the project week made it possible for the students to experience learning as a pleasant, creative and inspiring process. Further goals of the interdisciplinary project week were to sensitize the pupils towards sustainability, inspire them about related professions, and make the children lose their dread of do-it-yourself-constructions. The interdisciplinary mixture of theory, experiments, lectures and practice also contributed to a better learning success.
On the first two days, the students worked through interdisciplinary study contents especially compiled for the project, including small experiments to consolidate the knowledge. They split into the four groups Water & Plants, Energy Conversion, Solar & Electricity and Climate Change. As the final step of the theoretical phase the students passed on the results of their learning to their classmates according to the Teaching Principle “Students Teach Students”.
On the third day, the practical phase began with lectures by professionals in order to inform the students about job profiles and to familiarize them with the addressed topics. Subsequently, the scholars started to build the constructions with partial guidance from the professionals. In particular the executions were supported voluntarily by solar expert Thomas Stodder of EB-Solarled as well as by physicist Moritz von Buttlar who invented the idea of an LED-lamp made of beverage cans.
Besides the wastewater treatment, the students also built an electric circuit based on 12 Volts including a battery, a charge controller and different connections. It is fed by solar modules on the school roof. Furthermore, the students constructed a 12-Volt room lighting with LED ceiling light and LED reading lights self-brazed of recycled beverage cans as well as a current generator tinkered out of an old bicycle and pieces from the scrap yard. They also insulated the decayed old windows of the building as far as possible with insulation foil and rubber seal, kindly sponsored by tesa, pointed out energy-saving deficits and developed specific actions for the classroom.
The project week was a pilot project. In the next steps, the concept will be revised by the students and made transferable to other classes and schools in order to give them the possibility to experience this innovative project week, just as Lydia and her classmates did.

In Germany only 16 percent of all teachers feel that they are “well” or “very well” qualified to teach natural sciences education. According to Prof. Dr. Jörg Ramseger (professor of educational sciences and director of the department of educational investigation at the FU Berlin) the children’s motivation for research, from primary education onwards, is not promoted ambitiously enough by educational officers. “Education starts with curiosity”, says Prof. Peter Bieri. From the early years onwards, children should be motivated in the sciences, because later on, they will mostly lose this interest.
At the Evangelische Gesamtschule Berlin Zentrum (Integrated Evangelical School of Berlin Centre, esbz), a cooperation with the Blue Economy has resulted in a transferable instruction concept for the area of sciences.
The esbz was founded as a reform school with a radical change in learning concepts. As an autonomous school it aims to set an example regarding viable developments. The school is committed in a special way to the ambitions of AGENDA 21, hence it is also called “AGENDA-School”.
The motivation of the team surrounding Mandy Voggenauer, sciences teacher at the school, is based on active and cooperative learning, as well as creative and critical thinking. The teachers take over the role of a moderator within the learning process, encouraging the children to answer questions, to elaborate on a result and to reach solutions independently.
Now, after a one-year-long pilot period, the first results capable of being replicated are available and can be transferred to other schools.
As a first step, the students elaborate on new perspectives based on some fables by Gunter Pauli, in order to learn how everything is interconnected in science. These fables promote systemic thinking and emotional intelligence, the understanding of their own strengths and weaknesses, as well as those of others. Thus, they recognize and respect differences, manage their emotions more effectively and interact respectfully with others. These are crucial aptitudes in the children’s lives, enabling them to cultivate a harmonious relationship with themselves, others and their environment.
Different practical projects are carried out, based on the fables. The production of fertilizers and soil from food waste, plant cultivation, energy generation, flying objects and many more, enabling the students to experience in practice the knowledge acquired in theory.
This open structure quickly provoked a series of socio-political questions: Where does our food come from today? Why are the Earth´s resources used in such an inefficient way? What can each of us do to make some changes at grassroots level? In this way the students better understand and absorb the subjects and their backgrounds, bearing in mind that “education is what is left behind when we forget what we have learned”. (Edward Frederick Lindley Wood).
At the first Parent Campus, the students gave an impressive display of what it means to present their own knowledge and opinions, becoming involved in scientific discussion with their parents.
At the same time, the basic curriculum must not be neglected. “I always care about integrating the curricular subjects into the projects in order to not provide less for the children, but rather give it a finishing touch”, says Mandy Voggenauer.
Now the project at the esbz will enter the next level. During the summer a whole week will be devoted to connecting the philosophy of the Blue Economy and sciences to the elementary school curriculum.
In theory and practical experience, the students will again be taught the sensibility of sustainability, as well as becoming acquainted with different professional fields.
The project week “Autonomous Classroom” is a transferable and multi-disciplinary instructional concept which aims to motivate the students beyond the framework of the regular lessons with its interdisciplinary approach. A systemic subject will be the base to become better aquainted with the details of some other subjects such as German, English, mathematics, sciences and social science.
Markus Haastert, president of ZERI Germany and Blue Economy, has become a committed partner of the esbz. In this way, the school could become a pioneer where “an educational module for the next generation will be developed from this economically, ecologically and socially visionary concept”, affirms Margret Rasfeld, director of the esbz.

Today we are leading a life which our planet can only sustain for a limited amount of time. Yet more than half of the people living on our planet cannot even fulfil their basic needs and must have a right to growth. Our society’s future and economy’s sustainability are only conceivable if we learn to create more livelihood for an increasing number of people using less natural resources. For twenty years now, realisation is growing that the greatest physical threat to ecological subsistence is the huge and unnecessary waste of natural resources. Roughly 30kg of nature are used on average to create 1kg of technology, not including water. Without this technology, modern services cannot be delivered. More than 90% of de-naturalised environment used to create material wealth does not make a contribution towards fulfilling human needs and dreams.
When the heads of governments and nations meet in Brazil in June this year to discuss about a globally sustainable development, the question about defining a sustainable economy will also come up. It has taken a long time before governments have agreed about basic guidelines of the term “Green Economy”. For more than a decade, the “green movement” has been shaped without a unifying political image, leading to the present, multifaceted term of the Green Economy. Some prefer to call it “greenwashing”. Slowly a political consensus has been found that the Green Economy’s aim is a “naturally supportable economy of low emissions”. Of course a constituting policy of regulation is necessary to follow this path, which supports businesses orientated towards innovation and reduces emissions of pollutants into the environment. In spite of all the progress which has been reached concerning this subject, we know that the Green Economy is only a step of transformation towards a change of paradigms in the social and economic development.
We call this new paradigm Blue Economy. Sustainable business in the spirit of the Blue Economy makes it possible to respond to the basic needs of all without exploiting the natural resources, but also without a need to renounce to commodities. In contrast to the Green Economy, the Blue Economy stands for a new way of designing businesses, a new market-oriented business model, sustainable businesses and sustainable growth. Blue Economy stands for making the good more accessible and the bad more expensive. Blue Economy stands for clean water, clean air and for Planet Earth.
The term Blue Economy means: Using available resources in cascading systems, the waste of one product becomes the raw material for a new cash flow. In this way jobs are created, social capital is built and the income increases – without further exploiting and damaging the environment, but rather conserving and improving it. This makes sustainable growth possible. The present global economic system can be transformed into a sustainable development by innovations and entrepreneurship. Innovations and better livelihoods are promoted by demand, by means of the free market and by education instead of inhibiting them with subsidies and social barriers.
The key is a holistic view of things, it is about intelligent synergies and connections of different levels (cascades) within (eco)systems which might not be visible at first sight. ZERI Foundation, founded by Gunter Pauli in 1995 in preparation of the Kyoto protocols, has been identifying and scouting examples of such new business models for many years, promoting them under the term Blue Economy. Now we need to search for dialogue in order to promote a holistic understanding of an interrelated world of production, integrating the basic resource of water as a pillar for plants, animals, algae and bacteria.
Growth and the Value of Nature
The ecological currency to create sustainable wealth is a maximum of achievable resource productivity. Material growth is the opposite. Today, anyone can extract resources from nature and use them profitably without paying an appropriate price. Today, humans use enormous amounts of energy to move more than 100 billion tons of material every year, not counting water and tilled land. This is more than double what nature can achieve. Therefore, the amount of resources utilized for welfare is an indicator that can be used to measure the potential environmental damage of all goods and services – the so-called material footprint. Ecologically, we hope to speed up processes which decrease the use of natural resources.
We could achieve this fairly quickly without decreasing our livelihoods and welfare. As far back as 2004, economists published that SMEs in Germany could save on average 20% of their cost for resources without decreasing the quality of output – i.e. more than 150 billion EUR p.a. . In other words, saving natural resources is worthwhile – but few companies have understood the benefits of increasing resource efficiency. It seems politics must set an incentive (for a limited period of time). It is scientifically impossible to measure the eco-toxic effects of economy in all necessary detail, never mind make accurate predictions, to be able to use such measures in environmental politics. As all indicators, resource productivity and intensity can only be an approximate indication of the potential environmental burden. Thus, prohibitions are of little use.
Instead, the price for extraction and use of nature must be adapted to the real cost. One possibility would be to shift the financial burden on labour to natural resources (macro-economically cost-neutral). This would seem appropriate since natural capital has increasingly become the decisive shortage for humanity, not labour. Only when the input of natural resources into the economic metabolism is at full-cost-pricing will innovations increasing resource efficiency take off. And the only environmental labelling needed would be the toxicity of products.
New Business Models
But we need to do more than save, i.e. increase efficiency. Equally important is the effectiveness, finding the best possible use for resources – thus creating far more value from the available resources. Today’s business model is focussed on material growth, economies of scale, core business and core competence and favours specialisation and concentration on select markets. Success in business is measured in cash and market share and not in the ability to create sustainable, lasting utility for consumers.
It appears we urgently need a new kind of business model to support a future-proof economy. One central prerequisite is to fulfil the basic needs of all for e.g. food, services and resources as locally as possible and self-responsibly – only then can Happiness be achieved. One example of how to increase value creation hundredfold based on modern habits:
From the bean to the cup of coffee, only 0.2% of the plant are actually consumed. In other words, 99.8% must be disposed of – 7.5 million tons of coffee grounds are at best burned or composted, or end up in landfills. Instead, this hard wood could be used to cultivate gourmet mushrooms; after their harvest, worms eat the leftovers, which results in fish feed and high-quality fertilizer. No waste remains, instead three new products and thus cash flows including jobs have been created. Companies in Berlin, San Francisco, Mexico City and Madrid are already using this model – while coffee corporates make zero use of the efficiency, resource and income potential, instead spending money on expensive ‘greenwashing’.
Business models published as ‘Blue Economy’ demonstrate that nature is the most efficient AND effective economist of our planet. All problems have multiple solutions which produce neither waste nor unintended collateral damage. Many highly toxic components of our products which cause large material footprints in their own production could simply be substituted by “nothing” – such as batteries can be replaced by natural electricity from temperature differentials. Orienting product design on natural physical principles opens an inconceivable potential, e.g. when water is cleaned using gravity as a sole source of energy (eliminating chlorine and expensive filters).
The result are products which are cheaper and better – better for all of us including nature. We hope that politics, business and consumers will realise that it is possible to live a sustainable ‘future’ today. All we need is a shift in mindset, not a relinquishing of wealth and need satisfaction.
A politics of local growth and sufficiency
To realise the potential already possible and known today, politics must set the scene. An elaborate program for innovation and value creation towards resource effectiveness should include:
– Preventive enforcement of systemic solutions [EU 6.1]
– Targeted improvement of resource productivity [EU 1., 6.1]
– Enforcement of real prices on the market (“full-cost-pricing“) [EU 3.4.2]
– Effective collateral damage responsibility in politics and business (Homburg)
– Agreement on ecological, social and economic goals for a stable future [EU 6.1]
– Definition of environmental indicators for all political areas [EU 1., 2. 6.1]
– Abolishment of consumption promoting subsidies [EU 3.4.1.]
– Limitation of short-term profit maximisation
– Prevention of “toxic products” (Stiglitz), [EU 3.1.2.]
– Provision of early warning systems,
-Establishment of dependable standards in accounting, reporting and labelling [EU 4.1].
We hope Rio+20 can achieve some significant steps in this direction, as time is running out. In July 2010, a study of the German military concluded that “there is a very serious risk that a transformation phase of economic and societal structures caused by long-term scarcity of important resources will not pass off without frictions at safety political levels. The disintegration of complex economic systems … has direct, profound consequences for many areas of life, especially in industrialized countries. … The foreseeable change in paradigms is contrary to economic logic and can therefore not be left to market forces alone” .
Without the eco-systemic services and functions that humans evolved from, human kind cannot survive on planet Earth. We all have to act immediately to protect our right to a future, but also the rights of the future: a right to life of happiness and well-being in harmony with nature.
