A problem cannot be effectively solved without understanding it fully in the first place [basic carbon vocabulary - MUST READ]





Climate change is the result of breakdowns in the carbon cycle caused by us:
IT IS A DESIGN FAILURE. 
***    ***    *** 

Anthropogenic greenhouse gases in the atmosphere make airborne carbon a material in the wrong place, at the wrong dose and wrong duration

It is WE who have made carbon a toxin—like lead in our drinking water. In the right place, carbon is a resource and tool.

The world’s current carbon strategy aims to promote a goal of zero. Predominant language currently includes words such as “low carbon,” “zero carbon,” “negative carbon,” and even a “war on carbon.”

The design world needs values-based language that reflects a safe, healthy and just world. In this new paradigm, by building urban food systems and cultivating closed-loop flows of carbon nutrients, carbon can be recognized as an asset rather than a toxin, and the life-giving carbon cycle can become a model for human designs.

***    ***    *** 

The new language signals positive intentions, leading us to do more good rather than simply less bad. It identifies three categories of carbon:

  • *** Living carbon: organic, flowing in biological cycles, providing fresh food, healthy forests and fertile soil; something we want to cultivate and grow
  • *** Durable carbon: locked in stable solids such as coal and limestone or recyclable polymers that are used and reused; ranges from reusable fibers like paper and cloth, to building and infrastructure elements that can last for generations and then be reused
  • *** Fugitive carbon: has ended up somewhere unwanted and can be toxic; includes carbon dioxide released into the atmosphere by burning fossil fuels, ‘waste to energy’ plants, methane leaks, deforestation, much industrial agriculture and urban development
Working carbon is a subset of all three categories and defined as a material being put to human use. For example, working living carbon is cultivated in agricultural systems. Working durable carbon is recycled, reused and reprocessed in circular technical systems; and working fugitive carbon includes fossil fuels used for power.


The new language also identifies three strategies for carbon management and climate change:

  • *** Carbon positive: actions converting atmospheric carbon to forms that enhance soil nutrition or to durable forms such as polymers and solid aggregates; also recycling of carbon into nutrients from organic materials, food waste, compostable polymers and sewers
  • *** Carbon neutral: actions that transform or maintain carbon in durable Earth-bound forms and cycles across generations; or renewable energy such as solar, wind and hydropower that do not release carbon
  • *** Carbon negative: actions that pollute the land, water and atmosphere with various forms of carbon, for example, CO2 and methane into the atmosphere or plastics in the ocean
Offering an inspiring model for climate action begins with changing the way we talk about carbon. 

Our goal is for all to embrace this new language and work toward a Carbon Positive design framework; and in doing so we may together support a delightfully diverse, safe, healthy and just world—with clean air, soil, water and energy—that is economical, equitable, ecological, and elegantly enjoyed.

Summer 2016

ECO-EFFICIENT ARCHITECTURE WORKSHOP
LEARN - DESIGN - BUILD

ONE PROTOTYPE FOR DEVELOPMENT



@ Abetenim Art Vilage [Ghana]



by 

in collaboration with 



Why Eco-effectiveness?
 Eco-effective architecture presents an alternative design and construction concept to the strategies of zero emission, sustainability and eco-efficiency. Where these seek to reduce the unintended negative consequences of processes of production and consumption, eco-effectiveness is a positive agenda for the conception and production of architecture that incorporate social, economic, and environmental benefit, enabling triple top line growth




WHEN
June-July 2016.

The workshop will run for about 8 weeks.
Join at any time and participate for a minimum of two weeks.

WHERE
Abetenim Art Village - Ejisu-Juaben District [GHANA]


Abetenim is a rural village surrounded by astonishing landscapes and gorgeous wildlife located 40 Km North-East from Kumasi, once the capital of the rich and powerful Ashanti kingdom, Ghana's second city is still dripping with Ashanti traditions. This region is a nature lover’s delight. It has sunny equatorial climate and fertile well-watered soils sustain and enchanting selection of wild life ranging from elephants to monkeys and marine turtles to crocodiles. More of the 5% of the country’s surface area has been accorded official protection across 16 national parks of which the most popular is the vast Mole National Park.
Participants will have short breaks from the construction works to visit the Boabeng-Fiema Monkey Sanctuary or a cool off all day at the Kintampo waterfalls at Sunyani. Along the way you will be further exposed to architecture in other parts of the country. Over the weekend, participant can explore the nearby cultural sites such as Bomwire Kente Village, Bobiri Forest Reserve, or the cultural centres of the historic city of Kumasi that bring cultural tourism to the region. Or, can spend the rest of the free time collaborating with indigenous musicians, weavers, storytellers, or teach some of the life skills you have to the local school children. After the workshop, it is your time to relax and be a tourist. You may take your time to visit other places you really would like to see of which the region is known, whether for your academic interests or sightseeing like vacationers.

HOW
By a LEARN, DESIGN & BUILD process

WHAT

Based on an eco-effective architecture approach, we will be prototyping a house to be used for international and local artists as a space to live and to create while visiting Abetenim Art Village. The goal is to develop an engineered solution which is the most effective in its context, has a positive incidence in both the environment and the community and whom technology and knowledge are replicable locally.



LEARN

A three steps method is proposed. First the team will enjoy a deep engagement with the community through respectful observation and cooperative processes. A second stage for the analysis of the local needs, initiatives, traditions, landscape, resources and climatology. And a third stage of theory lessons about eco-effective architecture



DESIGN

Although the design is based on a collaborative approach where the decisions are taken by the team, there are some strategies that are predefined by the workshop motto for the architectural prototype process like: Clean water, air, soil and power, up-cycling of materials ["cycle of life" thinking], zero waste, local empowering, bioclimatic design and low cost.



BUILD

This is a hands-on full-on site-specific workshop experience and It promises high-impact learning practice gaining global experience for both personal development and professional growth. Most evenings will be used for reviewing construction progress along with informal discussions and presentations by the workshop leader, local community and international participants.

POO power








In early January 2013, Kenya’s oldest English-language school, the Maseno School, opened new dormitories for 720 students, and it had a couple of problems. Pit latrines and a faulty sewage system inevitably left foul odors and polluted local freshwater sources, while the kitchen used firewood for cooking fuel—unhealthy for cooks and the environment alike. High school senior, Leroy Mwasaru, now 17, and four of his friends had an idea: to harvest poop and other waste and turn it into a safe, clean and eco-friendly source of cooking fuel. Check out this video courtesy of Makeshift, and read on past the jump to learn more about the project!

What Mwasaru and his friends proposed was to build a Human Waste Bioreactor (HWB) that would harvest not only the waste from all the students in the dorm, but also organic waste from the kitchen, cow dung and slashing grass to create biogas for cooking fuel. As Grist explains, the HWB is “an underground chamber holds the human, animal, and kitchen excrement, while microorganisms go to work breaking down the muck. This process releases biogas, a source of renewable energy comprised mostly of methane, the same as the fossil fuel natural gas that powers most non-electric stoves in the U.S. The gas is contained in the HWB, ready for use as fuel.

The final version of the HWB will cost around 7 million Kenyan Shillings ($85,000) to build and install, but Mwasaru estimates that it will cut the school’s cooking fuel costs in half while providing numerous benefits for the health of the local community and environment. After that? Mwasaru hopes to turn the project into it’s own company, charging customers according to their ability to pay, so as to provide clean fuel and sanitation services to poor or off-the-grid communities.

The life cycle of a PET plastic bottle


Plastic bottles are used to package a wide variety of things, from juice to soft drinks, and they play a ubiquitous role in the lives of many consumers, along with other plastic products. With a growing awareness of the environmental issues which surround plastics, many people have become interested in the life cycles of plastic products, from manufacturing to eventual disposition in a landfill or recycling facility. Being aware of the process behind the production of plastics can encourage consumers to think more carefully about how they use and dispose of such plastics. Because plastic bottles are a very visible form of plastic use, plastic bottles make an easy target for activism and education.



The life cycle of a plastic bottle starts, obviously, with the creation of the plastic used to make it. The vast majority of plastic bottles are manufactured from petroleum, some of which comes from deposits as much as three billion years old. Some manufacturers use bioplastics made from plant materials to create their plastic bottles, out of concern for the environment.
In the case of a plastic bottle made from petroleum, the oil must be extracted before being shipped to a processing facility and then distilled to separate out the various hydrocarbons it contains. Oil extraction is performed all over the world in a variety of locations, and it has a number of environmental impacts. In areas where oil is drilled from the seafloor, for example, oil spills are common, and regions like the Middle East are famous for their heavily polluting oil fires, caused by intentional or accidental combustion of oil fields. In some nations, oil extraction is also bound up with a number of social issues. Nigeria, for instance, has an oil industry notoriously plagued with problems; oil workers are often poorly paid and exposed to very hazardous conditions, and periodic devastating fires along oil pipelines are not uncommon.

Once oil has been extracted, it is typically moved into container tankers for shipping to refinery facilities. At a refinery, the oil can be submitted to a variety of distillation processes, such as fractional distillation, where the crude oil is heated, causing its various components to separate so that the refinery can make gas, fuel oil, plastics, and a variety of other products. Crude oil can also be “cracked” with chemical catalysts to generate hydrocarbon chains of a desired length; this practice is common, because demand for various petroleum products constantly fluctuates, and cracking ensures that oil is used extremely efficiently and generates the maximum possible profit.
Most plastic bottles are made from polyethylene terephtalate (PET) plastic, and almost all water bottles come from virgin plastic; an estimated 30% of the world's PET goes into plastic bottles. The plastic used in plastic bottles is made by mixing hydrocarbons extracted from crude oil with chemical catalysts, triggering polymerization. Next, manufacturers produce plastic pellets, which are melted down into “preforms,” which look like small test tubes; the preforms, in turn, can be heated, causing them to expand and turn into conventional water bottles. Typically bottling companies order preforms, expanding the water bottles at their own facilities as needed.



Water bottles produced from bioplastics are made from plant materials which are processed to form polymers. Bioplastics are believed to be better for the environment, since they do not require the extraction and handling of crude oil, a non-renewable resource, and companies which manufacture them often try to use the best possible environmental practices. Furthermore, bioplastics decompose rapidly; the life cycle of a plastic bottle made from bioplastic is extremely short. In fact, some bottles made from bioplastics will even start to deform and leak if they are kept on the shelf too long.



However, bioplastics are not without environmental issues. The production of such plastics requires dedicating large areas of farmland to the production of crops for plastics, rather than food, and these crops eat up a great deal of water, fuel, and other resources. Bioplastics must also be manufactured with the assistance of a variety of chemicals, and, like regular plastics, they require shipping to an end destination, consuming more fuel along the way. Because they are designed to be disposable while still being relatively environmentally friendly, some activists fear that they may also distract consumers from more environmentally friendly choices, like reusable glass and metal containers.
Depending on the size of a bottling plant, a company will either order preforms and use them as needed, or it will order plastic bottles which are ready for use. The plastic bottles must be sterilized so that they are safe for beverages, and then they are filled, capped, labeled, packed into cases, and prepared for shipping. 




At this stage in the life cycle of a plastic bottle, the bottle could end up in any number of places, from a relief camp for refugees to the shelf at a high-end supermarket.
One distinct advantage to plastic bottles, in the eyes of manufacturers, is that they are extremely sturdy, making it much easier to ship beverages in plastics than glass, cardboard, metal, and other containers. Plastic bottles are also extremely lightweight, with manufacturers constantly coming up with new ways to use less plastic in their containers to cut down on the cost of production and shipping. Shipping materials in lightweight materials is also good for the environment, as it cuts down on fuel costs.
Once a PET plastic bottle ends up in the hands of an end-consumer, it has three possible fates after its contents have been consumed: it may be reused, recycled, or thrown away.


 PET bottles recycling process

recycling of PET bottles requires large amounts of water and energy

Despite the fact that most plastic bottles are made from PET plastic and this plastic is very easy to recycle, recycling rates for plastic bottles are actually very low, globally. Anywhere between 15-35% of plastic bottles make their way into recycling facilities, depending on the region, with the rest ending up in landfills or as litter. Some countries have attempted to address the low recycling rate with incentives, but because plastic bottles are cheap and easily accessible, many of these programs have not worked.


Many people believe that re-use, followed by recycling, is the best use for a plastic bottle. PET plastic can be reused, although people should avoid using it to contain hot or corrosive materials, and they should take care to wash such bottles out carefully. Plastic bottles can be very hospitable for bacteria, thereby potentially causing a health risk for people who drink from them. After a plastic bottle has been reused as many times as possible, it should ideally be recycled.


In recycling, plastic bottles are shredded into chips which are then sterilized and sold to companies which produce products made from recycled plastic. This stage in the life cycle of a plastic bottle can get quite interesting, as these plastic chips can be used for everything from fleece blankets to artificial lumber. Many products which are made from recycled plastic clearly indicate this, for consumers who would prefer to promote the use of recycled, rather than virgin, plastics.



When a plastic bottle enters a landfill, it can take hundreds of years to decay, and it can have a profound environmental impact. The route to the landfill is often quite long, as plastic bottles are a very common form of litter around the world, requiring volunteers or government agencies to collect such bottles and bring them to a facility for recycling or other forms of disposal. As plastic bottles decay, they take up precious landfill space, and some leach harmful chemicals into the ground, potentially polluting the soil and water.




 plastic codes
ekuazion recommend avoiding the use of these two types of plastics: PVC and PS (polystyrene)


Because landfills are so tightly packed, some scientists are concerned that the rate of decay in landfills could be even slower than previously surmised, as the conditions are not optimal for breakdown. Landfills in general pose a serious problem in many parts of the world, as they contain a broad mixture of items which could potentially be recycled, including precious metals, along with potentially dangerous and toxic products. Plastic bottles take up an alarming amount of landfill space, especially when one considers that they shouldn't be in landfills at all.



Not all discarded plastic bottles make their way into landfills, either. The world's oceans host a steadily growing collection of plastics, most notably in the Great Pacific Garbage Patch. These plastics come from litter, poorly secured landfills, spilled shipping containers, and a variety of other sources, and they take centuries to break down, even assisted by corrosive saltwater and UV radiation. The proliferation of plastics in the world's oceans poses a serious threat to many marine organisms, and some scientists are concerned that, rather than breaking down entirely, plastics actually break down into very small segments which could potentially be consumed by microscopic organisms.
This could have serious environmental repercussions, as such organisms are not equipped to digest plastics. Therefore they could die in mass numbers, or be consumed by animals higher up the food chain. This could potentially cause such predator organisms to accumulate a variety of the hazardous substances used in plastic production, leading to a breakdown in the health of the world's oceans as well as impacting the health of animals (including humans) which use these organisms as a source of food.
In the case of plastic bottles manufactured from bioplastics, the life cycle of a plastic bottle is quite a bit different. Many such bottles are designed to be disposable, and they will quickly compost under the right conditions, typically those found in a municipal composting facility, rather than a home compost heap. When composted, bioplastics simply return to the Earth; when such plastics end up in landfills, they will also break down, although the decay process may take longer, due to the lack of aeration in landfills.


The stages in the life cycle of a plastic bottle are largely determined by the type of plastic it is made from and the people who interact with the bottle over its lifetime. Because consumers have a powerful role in the end fate of the plastics they use, many environmental organizations have focused heavily consumers, asking them to reduce their use of plastics, reuse them when possible, and ultimately recycle them, in the hopes of reducing the environmental impact of plastics.







The next time you see something in a plastic bottle at the store, you can think about the fact that it contains substances which are billions of years old, and that it may have traveled across great distances to reach the shelf.
