The project “Greenwasher, active sustainable chamber” is a research on a DIY contemporary lifestyle.   The first part is a manual of “how to make yourself” a complete system to produce at home all goods for contemporary living, such as electricity, biogas, food and biodiesel while collecting heat from the sun and rainwater. The following characteristics make the system the perfect solution for global sustainability: low-budget for broad application, local production and reuse of materials and therefore less energy required in the process, biologic food production and green energy production. The second part is an application of the manual in a one person’s habitat. The aim is to minimize use of natural resources and co2 emissions during the building and living process. The idea for creating the manual began with the collection of systems aimed at an ecologically bearable conscious contemporary lifestyle. Next step was the restriction of the system to “do it yourself” version. For this reason we studied «how to» and «Do It yourself» youtube videos and websites that offer such expertise to ease of manufacture and low cost.  Adaptations were made in the way of building the systems with emphasis on the implementation of used items. Changes or adjustments of the use of objects are possible. Finally, we combined all segments in a single system in a “nothing is wasted” concept. Special feature is the excessive economy. In other case would be characterized meanness. With neurotic patience, the user utilizes the water through a hierarchy system of value, until that evaporates. Moreover, by simple chemical processes, produces useful goods from useless garbage, while producing no waste, since he re-uses everything. One could describe the model as a concentrated version of the complexity of gathering the goods of modern life. As regard the aesthetic issue, we can talk about a new species of architecture that is free of the question about form; the appearance is simply what derives from the collection and assemblage of existing systems and elements. The project seems to be the perfect sustainable solution on building and living. However, the personal motivation, time and effort required, opens the discussion about changes that could be done in the society, political and economic system to make this lifestyle possible for everyone. 1295294311-greenwasher-444x500

The idea for creating the manual began with the collection of systems aimed at an ecologically bearable conscious contemporary lifestyle. Next step was tthe restriction of the system to “do it yourself” version. For this reason we studied «how to» and «Do It Yourself» youtube videos and websites that offer such expertise to ease of manufacture and low cost. The low cost factor has a similar relationship with the construction of ecological factors when taken into account the reuse of objects. Thus, adaptations were made in the way of manufacturing systems with emphasis on the implementation of used items may change or adjust the use of objects. For example, a reused tub acts as a tank – aquarium in the hydroponic / aquaponic system. Finally, we combined all segments in a single system with the logic that “nothing is wasted”.The elements that trigger the system is water and sun. Water can be collected from the roof when it rains through the gutters and stored in tanks. Using a filter and proper maintenance of tanks, this water is drinkable. The clean water goes to the sink. Whatever is spent for washing dishes and washing vegetables led to the cistern where it can be reused. The toilet waste is transported to the burner biomass. There, may also be led discarded remnants of food and the excess biomass of algae after extraction of oil. The biomass after fermentation process gives biogas, which, passing through a boiler can heat water for radiators and showers. The radiator may be used only in conditions of lack of solar energy, ie when the solar heater can not operate. Biogas can be used for cooking when there is not enough solar energy to function the solar oven. The low quality of water leaving the boiler biomass after fermentation with the waste water in the shower, can be reused in the cultivation of algae for biodiesel production. This led to a tank http://premier-pharmacy.com/product-category/alcoholism/ where it is mixed with a small quantity of microalgae, some nutrients plus carbon dioxide, while the contaminated water contains enough already. The mixture is sent by a pump in transparent tubes. After a day of exposure to sunlight, the algae have grown considerably. Harvesting can be done in a container covered with a filter that keeps the biomass from the water. The water can be sent back to the tank algae. The biomass of micro-algae left in the sun to dry. The paste is dried biomass is transferred to an oil press. The extract of the oil must be transported to the biodiesel processor to make biodiesel fuel. The hot water process requires heat on biogas. For the operation of pumps of the machines, a photovoltaic installation is necessary. Electrical energy is stored in a second hand car batteries, and in sufficient quantity, can supply power throughout the house. Regarding nutrition, a hydroponic system combined with a aquaponic system can provide daily fresh vegetables and fish and rice, cereals, soybeans and nuts. Food can also be some species of algae. For hygiene, soap can be made by algae. During the treatment process of vegetable oil from algae into biodiesel, glycerin derives, which can be mixed with seaweed paste, essential ingredients of seaweed soap. The representation of the parts is real, but not unique. Is an example that may be arranged according to specific needs and circumstances of the users and the environment. Also, the lack of space and time, can result in a party and not the entire system. Built in its final form and ideal environmental conditions, can offer complete self-sufficiency with zero energy footprint. However, this means full-time working in the system daily. The representation of the system is graphical. Can be tailored to each building plan, including an apartment in a more concise form. Feature is excessive economy, which would otherwise be characterized meanness. With neurotic patience, the user utilizes the water through a hierarchy system of value, until evaporated. Moreover, by simple chemical processes, produces useful goods from useless waste, while producing no waste, since he re-uses everything. The appearance of the system seems complicated, but consists of humble materials. It is an assembly of used items, garbage, cables, pipes and fluids of changing purity, transparency and clotting interfering or cooperating with the building. One could describe it as a concentrated version of the complexity of gathering the goods of modern life. The same thrift-austerity is applied to diet. The range of food of the user is much more limited than the range that can be found on the market. Consume only locally produced seasonal and organic food, avoiding meat, appertaining the model of macrobiotic diet. He does not consume more than he needs, many times consumes the food raw and when the cooks, the cooks with solar energy or biogas. However, if someone does not wants to follow a strict macrobiotic diet model, it is possible to add animals. Indeed, animal waste can be used to the system to produce more biogas. This, however, needs land and conflicts with the hydroponic soiless concept. Although the model is rural, it is possible and even recommended that the cities, as there is no need for land. The hydroponic / aquaponic crop can be inside, close to major openings to the south, on balconies, patios and terraces. Indeed, the balcony is ideal because it can easily be turned into glass during winter by adding nylon. With the growing algae does not need anything but light and water and could be grown in transparent tubes or bags on the southern sides of buildings. As the algae grow faster with the addition of carbon dioxide could capture carbon dioxide in polluted urban air and acts as a barrier of improvement of the atmosphere of the building. It is a more flexible model of urban farm. Besides, while urban farms still look like farms, this model can be presented as architectural element, for example, a facade which consists of transparent tubes containing algae.
