The Australian government is investing around $53 million in a Tasmanian company that plans to refurbish a coal kiln to burn wood “waste” and used tires for cement production. Federal Minister for Climate Change Chris Bowen advocates this as a step toward decarbonizing the economy. However, critics argue that burning forest biomass, considered a renewable resource, releases significant amounts of carbon, potentially exacerbating forest health deterioration.
Concrete production is responsible for up to 8% of global carbon emissions, mainly due to the emissions from clinker processing and fossil fuel use. While biomass is promoted as a cleaner alternative, it has a much lower caloric value than coal and requires vast amounts of wood, which threatens ecosystem health and biodiversity.
Australia has committed to ending deforestation by 2030, recognizing the importance of forests for carbon sequestration. The Tasmanian initiative is part of a broader trend, with other projects like Verdant Earth Industries’ plan to restart a coal-fired power station in New South Wales, also aiming to burn biomass.
The article emphasizes that the government should not fund projects involving significant biomass burning. Instead, it advocates exploring truly renewable energy sources such as concentrated solar power, highlighting the need to pursue cleaner, more sustainable energy solutions.
