Of cement, chocolate & rum

LC3 Chocolate and Rum

Although many trendy bars now serve chocolate mojitos, a Swiss and Cuban mix is not obvious. Yet, when it comes to cement, Swiss, Cuban and Indian scientists have tackled one of the world’s lesser known but biggest challenges. As countries develop, demand for housing and infrastructure increases. Concrete is by far the most commonly used construction material to meet these needs, and cement is required to make concrete.

Post-disaster resilence and recovery

Some months ago we reported on a seminar in Guatemala, where the local Caritas had invited EcoSur specialists to pass their knowlege on to a group of young professionals who were interested in this ancient technology.

For Cuba, the flow of oil stopped suddenly with the collapse of the Soviet Union. While it will be for different reasons and from different causes, the end of the supply of oil is on the horizon. Countries could prepare for the future... if they want to.
The crisis hit all sectors of society. The oil dependent industrial model established during 1959-1990 collapsed with more than 50% cut of the oil supply. The government, however, chose to maintain all social achievements, especially in the areas of education, social security and health.
