Biosphere Technology is a waste to energy system that is designed to convert waste materials into green energy without causing any harm to the environment. The main goal of this technology is to provide industrial-scale production of energy to substitute oil.
The typical production of energy nowadays is through extraction of energy from fossil fuels like oil, coal, and natural gas. It is never new to us that all these sources create negative impacts to the environment thus affecting even our socio-economic development. Many incidents have been also recorded about the adverse effects of fossil fuels in the environment particularly to many endangered species. This includes the environmental disaster, oil spill in Gulf of Mexico which ravaged marine wildlife and ecosystems in the area. But the quest for sustainable energy can be feasible with the use of biosphere technology. If this technology will be further developed worldwide then it can eventually replace the use of oil for energy production.
Biosphere technology applies gasification process, wherein waste materials are entered into an oxygen starved chamber for thermal decomposition. They are destroyed using high temperatures and the heat produced is then utilized for running the steam turbine generating electricity.
Aside from the energy benefits that biosphere technology provides, it can significantly help in eliminating the problems on waste disposal. Since it utilizes wastes for energy production, it can generally cater all waste management needs. Unlike typical landfill systems and other standard waste disposal methods, this technology does not contribute to global warming and soil deterioration. The technology can recycle or destroy any kind of waste material without leaving any harmful residue or emissions. In fact, the biosphere technology has full compliance to all international atmospheric standard emissions such as U.S. EPA and European regulations.
Other by products of this technology includes carbon black, high alloy steel wire, pozzolanic ash and distilled potable water. All these products are marketable and beneficial to manufacturers thus can greatly help to economic development.
Integrating this technology in our energy production and waste management system will secure a sustainable, cleaner and greener environment in the future.Tags: energy from fossil fuels, revolutionary oil, soil deterioration, steam turbine, thermal decomposition
Over 500,000 tonnes of faces are openly defecated every day to the environment around the world. That’s enough to fill the 30,000 seat State de Genève, where the Euro 2008 football tournament kicks off this weekend, three times over. But the global sanitation crisis is not a mere game: it pollutes the very environment upon which humans depend. Providing toilets and protecting the environment would be a winning combination for people and planet, says the Water Supply and Sanitation Collaborative Council (WSSCC).
Each year, more than 200 million tonnes of human waste go uncollected and untreated around the world, fouling the environment and exposing millions of people to disease and squalor, says Jon Lane, WSSCC Executive Director. On World Environment Day, midway through the International Year of Sanitation, WSSCC is calling for governments, stakeholders and individuals around the world to accelerate the work to end these ongoing human and environmental catastrophes.
Doing so, he says, requires neither colossal sums of money nor breakthrough scientific discoveries. Using existing, proven approaches and technologies, and for about US$ 10 billion a year less than 1 percent of global military expenditure the world could meet the Millennium Development Goal sanitation target to halve, by 2015, the proportion of people without sustainable access to basic sanitation. And around ten years later, everyone could have a toilet to use. Achieving universal sanitation can, with proper financing, be accomplished through hard work on the ground, plain talk about toilets, strong leadership at all levels, and by creating demand for toilets among the 2.6 billion poor people who need them, says Lane.
Toilets, washing facilities, garbage removal, wastewater disposal, stormwater drainage: sanitation services such as these are a prerequisite for clean, healthy household and community living environments, particularly in dense settlements. Such sanitation services are also vital to safeguard environmental quality more broadly, especially the quality of water resources. The cost is high, conversely, where sanitation services are lacking. Water pollution stemming from poor sanitation costs Southeast Asia more than US$ 2 billion per year, and in Indonesia and Vietnam creates environmental costs of more than US$ 200 million annually, primarily from the loss of productive land.
A healthy living environment depends on sanitary toilets
In teeming informal settlements across the globe, the sanitation crisis is keenly felt. With no way to safely dispose of either faeces or garbage, around a billion slum dwellers must resort to flying toilets (also known as wrap and throw) and to dumping trash in public spaces. This situation is not limited to urban settlements; in impoverished city suburbs, small market towns, large villages and periurban settlements across the developing world, the public environment is full of waste.
The contents of bucket-latrines and pits, even of sewers, are often emptied into the streets. A recent study of Indonesia, for example, found that roughly one in ten people are exposed to open sewers and the open dumping of solid waste, and more than four in ten to open defecation sites. Poor sanitation creates a host of health hazards as well as a bleak and disheartening visual landscape. Roads are full of mud, puddles, and piles of garbage and debris, not to mention disease-carrying insects, microbes and rodents. The odours are often unpleasant.
Imagine a community of 10,000 inhabitants, 30 percent of whom practice open defecation. Since each person produces 150 grams of faeces a day, open defecation would result in 450 kg daily or more than 3 tons a week or 100 full dump trucks’ worth of human excrement annually deposited in the community. Living in a squalid environment harms physical and psychological health; is stigmatising; often presents employment challenges; and deepens human poverty. A healthy living environment, one that supports human dignity and is free of disease transmitting agents and conditions, is impossible without sanitation services.
Sanitary toilets aid environmental sustainability
Human waste enters water sources and land through open defecation, dumping of buckets, inadequate disposal via sewer pipes into water courses and onto unused land, and leakage from pit latrines. In the developing world, roughly 90 percent of sewage is discharged untreated into rivers, polluting waters and killing plants and fish. In Southeast Asia alone, 13 million tonnes of faeces are released to inland water sources each year, along with 122 million m3 of urine and 11 billion m3 of greywater. This presents a major health threat to people who depend upon open streams and wells for their drinking water as well as an economic blow to people whose livelihoods depend upon fisheries. Upstream water users find better quality water, whereas downstream users find sewage sinks. Water quality is worse near densely populated areas.
Reusing waste has many benefits
Sanitation involves a range of actions, but for a healthy environment in communities as well as in the larger natural world the top priority is separating excreta, with its host of biological pathogens, from contact with human beings as well as plant and animal life. In areas where it is practised, ending open defecation is a critical first step. But to fully realise the health, social, and economic benefits, the management of wastes must be considered. Conventional sewerage can now be supplemented with ecological sanitation technologies that make use of the nutrients in human waste. These range from simple arbor-loose where a tree is planted on the latrine pit to urine diverting toilets that produce fertiliser from urine and safely composted faeces. Anaerobic digestion of sewage to produce biogas for energy is another option.
In China today, for example, 90 percent of human excreta is used in agriculture the task is to make sure that raw sewage is not put on the fields. Chinese farming communities have proved open to the idea of urine-diverting, or dry, toilets that facilitate the re-use of excreta as fertiliser.
To support the awareness-raising effort on this and other key sanitation messages, the UN-Water Task Force on Sanitation has launched an advocacy and media kit in English, French and Spanish. Task Force Members include the United Nations Children’s Fund (UNICEF), World Health Organization (WHO), Water and Sanitation Programme (WSP), UNEP, United Nations Development Programme (UNDP), United Nations Human Settlements Programme (UN–HABITAT), United Nations University (UNU), and WSSCC.
World Environment Day, commemorated each year on 5 June and supported by the United Nations Environment Programme (UNEP), is one of the principal vehicles through which the United Nations stimulates worldwide awareness of the environment and enhances political attention and action.

The Green Revolution is here! Many are concerned about saving the planet and restoring it to its pristine glory.
Is it a movement just for the elite?
The green movement is currently a lifestyle choice that people can embrace if money is available to buy organic food and hybrid cars. It is important that it should become main-stream if it is to have any real influence on all of us. The green solutions prescribed by pundits are expensive and many are not able to afford them. How many of us can afford to install solar- powered panels on the roofs of our homes? These are expensive consumer choices. However, it goes without saying that environmental concerns are the topmost priority.
What is a sustainable blog?
A sustainable blog brings out ideas from different sections of the society to lessen noxious emissions and suggest ways to use clean and green technology that is simple and accessible. For instance, instead of throwing away plastic bottles, why don’t you give them away to the factory to make polyester? Polyester garments are an eco-friendly option.
Its importance in the virtual world
* Global warming is not something that is going to happen ten or twenty years from now. It is already happening.
* Unfortunately, governments and industries have been slow in waking up to this fact.
* Blogs and online communications are an excellent way to keep the pressure on the state for concrete action and measures to minimize the effects of climate change.
* These are advocacy tools by means of which extensive and broad campaigns can be conducted by environmentalists and the civil society to save the planet from further destruction.
* Everybody has a stake here and a significant role to play.
* Eco-themed blogs from around the world discuss issues on the current eco crisis and the measures to tackle it by sustainable means.
* You would be able to know about clean technology in the UK, climate change concerns in Italy or green farming in Canada.
It is important that an economy has to evolve from green technology and provides a sustainable life to us. A sustainable community would suggest ways to minimize our negative impact upon the planet. There has been a growing awareness among environment and sustainable groups to ensure that the existing resources on the planet do not get wastefully depleted.
The future generations should not suffer for the negligent actions of the past and present communities. Sustainable living is not an option. It is a necessity.
Overpopulation and a fierce battle for resources have wrecked havoc on the fragile eco-system of our planet. It is imperative that you should be conscious of your actions in conserving the planet by eco-friendly methods and limit over-consumption.
The environmental rating tool BREEAM is put under the spotlight in a podcast from green office design experts
The podcast is the second in the Green Office series, being produced bi-monthly by Morgan Lovell, where listeners can hear about the latest trends, technology and people in the world of green office design.
Martin Townsend, the director of BREEAM at BRE Global, starts off this latest episode, explaining how BREEAM – short for the Building Research Establishment Environmental Assessment Method – is helping to future-proof buildings and instil a conscientious effort among design professionals to include sustainability at an early stage in their building projects.
Podcast presenter Paul Kelly then sets off on a tour of London’s Charles Darwin House, a 1959 building in Roger Street recently awarded a BREEAM Excellent rating – achieved by reducing high energy usage and waste, whilst increasing comfort and satisfaction for the building’s users.
Listeners are taken on a tour of the building, which is home to three learned societies, the British Ecological Society, the Society for Experimental Biology and the Biochemical Society, with Dr Hazel Norman, who gives a fascinating insight into how inspirational design has helped achieve the challenging green standard.
To download the latest episode, log on to www.morganlovell.com/podcasts or subscribe via iTunes.
Paul Kelly, head of marketing at Morgan Lovell, said: “We hear so much about BREEAM and this podcast enables listeners to learn more about the standard and experience what it means to the people who work in a BREEAM Excellent office.
“The tour of Charles Darwin House also reinforces the fact that a BREEAM Excellent standard can also be achieved in older buildings and can deliver a range of inspirational features that boost staff morale and appeal to visitors.”
Sustainability is at the heart of Morgan Lovell’s work in office design and refurbishment. Its London office – based in Noel Street, Soho – scored the highest BREEAM rating ever for an office refurbishment of its type in the UK, winning both a Green Apple and BIFM Award – and the company has made the Sunday Times’ Best Green Companies list in 2008 and 2009.
A podcast is a pre-recorded ‘radio show’ that is posted for download on the internet, typically on iTunes. Users subscribe to a podcast and download individual ‘episodes’ to their iPods or MP3 players to listen whilst commuting, exercising or at home.
