An industrial pavilion and a road section, both in the Aveiro region, are the first visible results at real scale of using waste generated in the pulp and paper industry in precast concrete structures and in bituminous mixtures for roads paving in Portugal. The challenge, which is both complex and ambitious, emerged as part of the paperChain European project and is already being put into practice in Ílhavo and Cacia: using waste from pulp production, such as lime ash, dregs and grits (granular waste) as secondary raw materials in the construction sector, integrating them in a circular economy logic. The paperChain project includes 20 partners from five EU countries committed to circularity boosting). In Portugal, the entities involved include the University of Aveiro, The Navigator Company, Spral, Megavia, RAIZ Research Institute and the Sustainable Habitat Cluster. Called "New niche markets for waste from the pulp and paper industry based on the circular economy", it is coordinated by the company Acciona Construction (Spain).
The significant and potentially dramatic impact of climate change on forests, while well understood by foresters and scientists, is frequently overlooked in mainstream discussions, said Ben Gunneberg, CEO of PEFC International, on Earth Day today.
“Yet given the effect it will have on communities and ecosystems, we need to bring discussions about how to move towards ‘climate change adapted communities’ and ‘climate change resilient landscapes’ into the mainstream,” urged Mr. Gunneberg.
“When it comes to forests and climate change, the focus tends to be on the benefits that forests and forest products provide by absorbing and storing carbon and, conversely, on carbon emissions from such deforestation,” said Mr Gunneberg, speaking from the ICF National Conference 2015 “Tree Health, Resilience & Sustainability” in Cardiff, Wales, today.
“We need to become much better in communicating that climate change is threatening the health of forests around the world and that climate change has a significant impact on tree health, to enable us to be better prepared and better adapted.”
Forests are generally understood to have four major roles in climate change, summarizes the FAO:
they currently contribute about one-sixth of global carbon emissions when cleared, overused or degraded;
when managed sustainably, they produce wood fuels as a benign alternative to fossil fuels;
they have the potential to absorb about one-tenth of global carbon emissions projected for the first half of this century into their biomass, soils and products and store them – in principle indefinitely; and finally
they react sensitively to a changing climate.
The devastating effects of climate change on forests are already very much visible for example in British Columbia, Canada, where slightly warmer winters have enabled more pine beetles to survive, ruining millions of hectares of forests, with the associated effects on the environment, communities, and businesses.
