Abstract

Sustainable development is one of the most discussed themes worldwide, especially the effect of greenhouse gases emissions. Biomass has been presented in many studies as an important renewable alternative for energy source and feedstock. Charcoal is probably the most used and studied sort of biomass being used as energy source, reducing agent in metallurgical processes, activated charcoal for medical use, filtering agent for water treatment, and fertilizer. Given the importance of current moment of the world towards sustainability, this paper aims to prospect the technology development related to charcoal by using technological forecasting techniques based on patent documents analysis. The results have shown a considerable growth in the number of patent applications over the years, especially in the period from 2000 to 2009. Materials and Metallurgy is one of the main fields of patent applications in charcoal. Japan, South Korea, China, the USA and Germany stand out as the main assignee countries.
