7,000,000,000 tons per year carbon emissions

In the last 110 years, the global carbon emission has increased by about 14 times to more than 7,000,000,000 tons/year. The earth has no capacity to re-absorb this amount of carbon and might collapse, if we continue in the same way!

His future?

Laos is a poor country located in Southeast Asia. However, the country and in particular its former capital, Luang Prabang, is a beautiful place with many turist attractions. We have recently visited this country and discussed with some municipalities and universities on waste refining and converting to resources. In this visit, I met this boy, whose family are scavengers and live among the waste in such poor country. You may think what would be his future?

40,000 m3/hour biogas into the atmosphere

The recent leakage of oil in Mexican Gulf got a huge attention in the media. However, there are continuous threats to our environment that are generally forgotten or perhaps accepted. Ho Chi Minh City in Vietnam has one of these threats. This megacity with about 8 millions inhabitants has two landfills, receiving about 2,000,000 tons/year wastes. I visited one of them, which was covered, so full anaerobic digestion occurs and results in methane gas. The pipes collect this gas and lead directly to the atmosphere. A rough calculation on the amount of the biogas from these landfills point to about 40,000 m3/hour gas production (3,000 million tons CO2-equivalent per year). It is a serious continuous threat to the global environment, while it can be collected and converted to electricity or fuels. Let's hope that our initiation to collaborate with the country on "Waste Recovery-International Partnership" lead to improve this condition and a better global environment!
