Brazil aims to shrink World Cup's carbon cleat-print

Belo Horizonte, Brazil (AFP) Dec 20, 2011

With solar panels, recycled stadium seats and rain water sprinklers, Brazil hopes to make the 2014 World Cup the most environmentally-friendly yet.

At a dozen stadium construction and renovation sites around the country, builders are hoping to meet or even exceed new FIFA recommendations aimed at reducing the carbon footprint of the world's biggest sporting event.

"We are no longer accepting engineering works that do not take into account environmental sustainability," Jose Roberto Bernasconi, the head of the Sao Paulo architecture and engineering syndicate (Sinaenco-SP), told AFP.

Brazilian authorities are racing to build or renovate 12 stadiums in time for the event, and Sports Minister Aldo Rebelo pledged earlier this month that work on the venues will largely be completed ahead of schedule.

However, FIFA President Sepp Blatter expressed concerns over the weekend about Brazil's preparations, and other top officials have complained about the lack of infrastructure and poor public transport and roads.

But at the Governor Magalhaes Pinto stadium in the southeastern city of Belo Horizonte, planners say they have exceeded the world football body's sustainability guidelines and are looking to secure an official certification from the US Green Building Council.

Renovators of the stadium -- first built in 1965 -- are adding a six-million-gallon rainwater collection system and are deliberately sourcing materials locally to reduce fuel emissions.

All of the concrete removed from the original structure was reused in the renovations or other nearby projects, some 800,000 cubic meters of dirt removed from the site was used to patch up mining damage, and the original 50,000 seats were donated to local stadiums and gymnasiums.

"Everything was reused. There was no other waste or discarded materials that could have been reused," said Vinicius Lott, of the state government's Sustainable Cup project.

Builders plan to install some 6,000 solar panels on the roof to provide electricity to some 1,500 nearby homes.

"There's an idle roof receiving a lot of sunlight. So we decided to cover it with photovoltaic cells and turn it into a solar power plant," says Alexander Heringer, an electrical engineer involved in the project.

The $6.5 million solar plant will generate some 1.5 megawatts per hour -- a tiny fraction of the thousands of megawatts produced by a hydroelectric dam -- but the costs should be fully recovered during its 25-year life span.

The operating costs are also expected to be "very cheap" because the panels will require little maintenance and will be cleaned by rain water, Heringer said.

Brazil plans to offer an international tender for the panels -- which cannot be manufactured domestically -- and Heringer said German, Chinese, Korean, Spanish and Italian firms have expressed interest.

After the stadium's completion, the state government plans to launch similar solar projects at another stadium and an international airport.

Belo Horizonte, with some 2.5 million residents, expects to host six 2014 World Cup matches and three Confederations Cup matches in 2013.

The city -- Brazil's sixth largest -- plans to welcome 100,000 tourists during the World Cup, and the Minas Gerais state expects up to $2.8 billion in both public and private investments leading up to the event.

Americans Bullish That Advanced Energy Can Solve Problems and Strengthen Economy
San Francisco CA (SPX) Dec 19, 2011
Americans are gloomy about future costs for energy and the vast majorities are taking steps to reduce their personal energy costs, but they see economic benefits to emerging energy-saving technologies that they think will create jobs and strengthen the economy, according to a new survey. The Advanced Energy Economy (AEE) Survey found that 62 percent of Americans expect a gallon of gasoline ... read more
