Bitublock BALI CONFERENCE AND CONSTRUCTION INNOVATION IN SUSTAINABLE BIOFUELS

A new initiative born with a strong purpose, to accommodate the large number of waste generated and to introduce them back into the production cycle and reused.

The system is based on power recycle waste, but not just any garbage, ie not used wastes usually occur at home, but emerging waste would be recycled in certain industrial activities such as slag generated in the manufacture of steel, ash or glass.

The idea is to collect these wastes for blocks, that later would be used in the construction industry. The material used to make these blocks due its characteristics, confer resistance to these blocks up to six times higher than traditional concrete, in addition to relieving the amount of industrial waste and preventing the formation of new concrete cajetones largely minimizing environmental impact that implies.


These new blocks are called Bitublock and have been developed by engineer John Forth of the University of Leeds.

The different components of the new block is introduced into a mold of cement and are joined by a compound called bitumen, which confers the properties cajetón doing work on-duty as a block homogeneous.

This new system, according to experts, can revolutionize the world of construction, will begin shipping in about a year in the UK.

Companies using this new type of block may contribute to the protection of the Environment within the meaning of the reuse of hundreds of tons of waste and the fact prevent new blocks of concrete, thus sparing CO2 emissions to the atmosphere .

Will My Relocation Appraisal Be Higher

A joint collaboration between the UA (University of Alicante) and the company BSF (Bio Fuel Systems) have led to the creation of the first device which is capable of producing by a culture of marine microalgae , responsible for the absorption of CO2 atmospheric biomass from which get this new type of biofuel .

Cristian Gomis, chief project scientist and professor at the UA, presented yesterday the new building, which is the only of its kind to be found in a university in the world, which will conduct research in this field by applying the analysis dimensional because the prototype is a smaller scale than industrial systems. Gomis

emphasizes that this new prototype has the added advantage that it is a profitable , since the microalgae biomass generated through absorption of CO2 can be transformed into products "that have an important market value, ie, the prototype can be routed to the manufacture of cellulose or applications for the pharmaceutical industry . Such

biofuel can be a relief for the production of biofuels through planting of cereals, which are resulting in more of a debate on the real benefits of producing biofuels on a large scale, putting into question its sustainability and respect for the Environment .

How Do Pro-line Odds Work

BIODIESEL PRODUCTION BY COUNTRY OF KYOTO

has released a study conducted by researchers at the University of Wisconsin in which they show the data concerning the potential of each country to produce biodiesel .

The results are shown in a colored world map based on these values, ie the annual biodiesel production in millions of gallons that these countries could generate.
Thus we find that Uruguay, Thailand and Ghana are the countries favorable for production.

The results, researchers say, are arbitrary criteria, so if it takes into account many factors for these values \u200b\u200bmay have an acceptable consideration.
The researchers say that total production of biodiesel worldwide, only would be supplied between 4 or 5% of the total biodiesel demand.

researchers do not claim this study, trigger the production of biodiesel indiscriminately resulting in the countries as the most potentially favorable, but the goal is analyze the situation to avoid in this way, future problems resulting from the production of alternative fuels to oil.

Studies like this, again to emphasize, it is urgent to act against dependence of modern society with oil, because besides being a kind of energy most polluting and unsustainable , has a short lifespan, it is important to be clear about certain aspects, such as this, ie that countries could produce more biodiesel without changing greatly and produced a benefit for those in the economic field, for not the time comes in which the oil runs out and not having solutions cause a global chaos that would put the planet at one of the greatest threats in history.

Heart Burn With Right Hand Numbness

On Monday, the UN presented in the German city of Bonn, data emissions to the atmosphere of the member countries of the European Union in 2005.
This report should be noted that Spain is the country that more violates the goals of the Kyoto Protocol, in fact, Spain has not only reduced greenhouse gas emissions but in the period between 1990 and 2005 increased by 53.3% , which is very far from 15% increase that was allowed under the agreement signed in Kyoto, said Yvo de Boer, executive secretary of the United Nations Framework Convention on Climate Change (UNFCCC).

In general, the situation in which there is the whole of the European Union's breach of the agreement signed in Kyoto, in which member countries committed themselves to reducing their emissions pollutants into the atmosphere by 8% this value is a 1.5% , very unusual for Sweden, which has reduced emissions by 7.3% being its initial commitment 4% increase.
This trend of improvement, although less pronounced than in the case of Sweden, are also countries like France, Finland and the UK.

Therefore, the situation is not encouraging, because not only have achieved the objectives that emerged from the Kyoto summit, but these values \u200b\u200bhave worsened over the years in most Member countries of the European Union.

is clear that in the future, should implement policies much more committed and more stringent environmental field if it is to these summits and conventions are not just as dates on the calendar, but to be the beginning of a step forward in the fight against climate change .

BREACH OF AIR QUALITY THE WEB

department Environment of the Generalitat of Catalonia has proposed that citizens have at their disposal the data on the quality air they breathe and breathe, is ie, through the Web , users can meet air quality from the previous day, plus the forecast for today and the next.

The index indicates which are the air quality standards is the ICQA (Catalan Index Air Quality), the higher the value, the better the air quality.
The page displays the results in a very visual indication on the map of Catalonia air quality according to some colors (green, yellow and red) that are referenced with the quality varemos go from good to poor through improvement.

The information in this way has a greater visual ability to be understood by the majority of the population and leaving behind the numerical results and rigorous than previously used.

It gives the city an important information and allows the possession of a law, the environmental information .

LOW PARTICIPATION IN THE BLACKOUT

The blackout called to protest against climate change was called for today November 15 from 20:00 h to 20:05 h has had little impact in Spain. Specifically decreased only 160 megawatts, according to Red E lectric English (REE), a value that reflects the low turnout, it is recalled that the previous act was able to reduce electricity demand by about 1000 megawatts.

"itself may be off some buildings, but not strong enough to have a reflection," said Alberto Carbajo COO of REE. In addition Carbajo has discredited this sort of thing with claims that the outage may cause the "economic cost will be greater and even that" there is a greater emission of pollution "that is because the fluctuations in energy consumption in such a short time can cause problems in electricity supply.

The widespread off has been followed by public bodies mostly still very little public participation.

In the picture you can see the energy demand of the day, between 20:00 h and 20:05 h can be found to be negligible descent.

can not say that this call was a success, which should not be taken as an alarmist news, because in the opinion of the people, the idea was how are you that ideas are not effective in the fight against climate change .

What To Write On Sign For Baby Arrival

SAN SEBASTIAN

In just over two weeks, will light the streets of many cities and towns during the Christmas season. In the last few weeks debating whether it should be disposed such ornaments of the streets due to its consumption.

Into this debate comes to meet the city of San Sebastian in Guipuzcoa, where this year, its Christmas lights, which is expected to start in early December, is designed from a sustainable point of view because joint initiative San Sebastian Development, the Department of Environment and shops of the city.

Streets incorporate elements that will allow considerable energy savings .
traditional lighting of each year will be replaced by microbombillas, already used in other English cities, which cuts fuel consumption by about 70%, the decorations will include the installation of photovoltaic solar panels will be producing electricity, also public areas, bridges and squares are illuminated with LEDs, this type of lighting reduce consumption by 90%.

All the innovations made this year's Christmas lights will mean a reduction in energy consumption 80% over last year.

is an interesting initiative because it is difficult for cities to dispense with this type of lighting, because it gives the streets of an enabling environment for this time of year, so, you get that environment and reducing energy consumption, lighting style more sustainable could be used by the city council to make known to the public this initiative and to place the inhabitants of the city \u200b\u200bto do the same in their daily activities, so it would be getting that in addition to energy savings, a little more social awareness and sensitivity .
