Cell Phones: One of the largest causes of e-waste

The U.S. Environmental Protection Agency (EPA) says, “Recycle cell ¨

phones, it’s an easy call to make.” [1]

  

 

 

    

 

The average North American gets a new cell phone every 14 months.

According to the EPA, out of the 140 million cell phones discarded

by Americans in 2008, only about 10 per cent were recycled.

Moreover, their research concluded that if all the cell phones were

recycled, energy to 194,000 homes for one full year would be saved.[2]

Termites are Green Building Catalysts

 

The importance of graduating towards a greener existence has never engaged the kind of worldwide attention that it is currently managing, courtesy — the very, visible affects of worldwide global warming and the sough-after green solutions that are expected to be the outcome of the 2009 Copenhagen Meet.

Nearly every possible process that can create a more, ecologically responsible existence is being echoed as a possible solution to make urban living less straining on our environment. Among the many green initiatives that have been taken over the last couple of years, the prominence of eco-friendly buildings or green buildings has come forth as a universally accepted solution. In this regard, it may sound shocking to some folks that we weren’t the first to create ecologically efficient homes — this accomplishment belongs to a group of ground-mining and commonly detested, insects — termites! In an overall perspective, termite mounds can be understood as a marvel of nature’s own engineering. Often looked upon as a source of easy food for insectivores or as household pests, termites have been living a more ecologically compatible lifestyle than human beings have, since many millenniums!

 

Yes, termite colonies have now been confirmed as one of the most competent dwellings in terms of energy conservation that can compete with the biggest of green building claims that are commonly reported in the media. This isn't one of those scientific researches confirmed merely for academic interest. The termite’s mound (their living quarters) have actually inspired two green building creations that are now setting benchmarks for their decreased dependence upon conventional energy resources. This initiative was taken by an African architect, Mick Pearce, who created two buildings based upon the energy flows that were discovered within a termite mound. Eastgate Building in Zimbabwe and the Council House Building in Australia are two existing buildings that are being explored to understand, as to how an unassuming, supposedly under-developed insect in terms of intellectual capacity could create something so astonishingly effective.

 

Understanding Nature’s Green Buildings

For starters, the size of a termite mound or its house is an achievement in itself, if you compare the size of the buildings with the size of builder. If a precise analysis would be done, the ‘tallest building’ claims that we look upon an as a feat of humanity’s engineering success, are not even qualified to compete with the size-wise parameters set by these termite mounds. However, the real shocker is the precise temperature regulation that is done within the mound. Firstly, the interiors are completely insulated against the external heat — one of the main reasons why massive termite colonies can be found in the hottest of deserts. Secondly, each mound is built with a particular directional orientation to ensure that it receives the least amount of sunlight during the hottest part of the day. When the sun is about to set and the temperature is about to dip, the mound receives the maximum amount of sunlight to ensure that the interiors attain sufficient heat to keep the inhabitants comfortably warm, throughout the night. You should understand that some of these termite holdings are exposed to temperature variations, as extreme as 0 to 40 degrees within a 20-hr period. None of the most advanced, urban homes can sustain this kind of varying temperature without using climate control mechanisms that are powered by conventional fuel sources.

 

This automated form of climate control within the termite construction is achieved by designing the inner layers of the mound’s wall in a particular manner. The top of the mound has many microscopic pores that ensure minimal amount of air is always circulated to the inside, to maintain basic ventilation. The layers, deep inside the mound are further arranged in a method that has now been termed as the ‘stack effect technology’ which ensures that the cooler air from the top is continuously sucked-in and the warmer air is circulated to the outside. If this technology has to be compared with our homes, something very similar is done by the air-conditioning systems but then, they are powered by electricity and are heavy consumers of electrical power. This air-draft system in the mound doesn't require any kind of physical or electrical input and is completely self-automated. The only effort comes in the undemanding, periodic repairing of the wall wherein the termites ensure that he pores remain open and that evaporation from the mound is limited for which they keep piling a thin paste of wet mud on the inside.

 

Is this a realistic, adoptable technology or just fanciful thinking?

The entire concept is immediately useable in terms of its application to modern-day dwelling, particularly workplaces wherein huge investments are made to make the entire structure more, energy efficient. The two buildings based on the termite-building model are now termed as using a passive energy system for climate control. It is termed as ‘passive’ since no form of electronic control or any exhaustive equipment installation is needed to ensure that energy savings are being done and this is the biggest highlight. Here, energy savings aren't done through efficient, climate-control systems that are being retailed in supermarkets. Instead, the principle is to design the build to stimulate daily, energy savings without any activation, operational, maintenance or repairing costs. The Melbourne building also called the Council House 2 or CH2 and it has already achieved an 80% reduction in its energy use and an impressive, 70% reduction in water usage. The CH2 building’s performance in terms of energy savings has been more impressive since it has dedicated an entire section of the building towards ensuring easy management of day-night temperature difference wherein huge panels in a section of the buildings walls are left open during the evening and the air is circumvented in accordance with the passive energy system. These paneled shutters are automated, cheap-to-install, durable and need negligible handling in terms of employing manual effort. According to detailed analysis, the CH2 building has achieved savings close to $3.5 million which for a nearly 32,000 sq. meter complex is a breakthrough, energy-performance figure. Similarly, the Eastgate building is making daily, substantial savings since industrial air-conditioning plants weren’t installed. The building remains pleasantly cool during scorching daytime temperatures and basic ventilation assistance (like electric fans) is used as a supplementation for further cooling the interiors.

 

Is there a conclusion to be derived from this example?

The biggest conundrum that the adoption of contemporary green lifestyle trends faces is the affordability and the practical aspect of the proposed mediums. This has resulted in a deluge of many sub-standard, over-hyped green ‘solutions’ being marketed in the name of helping us becoming eco-friendly. As a result, many proposed green technologies are falling apart and some consumers are becoming vary of their realistic usage — a growing phenomenon that is now being termed as being ‘green-washed’, i.e. devious green consumerism being enforced upon us. In this deluge of misinformation about sustainable green solutions and our obsession of searching for ecologically efficient means of existence through research in artificial mediums, we are ignoring something very fundamental, i.e. our ecosystem. The environment that envelopes us is exhaustive, equipped with an underestimated form of bio-networking that can provide real-life, adoptable solutions — we merely need to devote out energies towards further understanding our ecology, rather than merely regarding it as an entity that needs to be safeguarded to protect our survivability.
