Role of Forests in Reining in Climate Change, Producing Energy

When it comes to the role of the forest in a perspective of climate change mitigation and energy production, a full picture including all aspects impacting their use and benefits is required to start to making sense of the “undeniably complex” discussion taking place in the media and politics.

All aspects of the forest as an economic resource, a provider of recreational value and its capacity for carbon sequestration should be considered, according to an academic expert on the matter.

Professor in Economics Robert Lundmark, Luleå University of Technology, tries to do just that, in a new report from independent nonprofit organisation Centre for Business and Policy Studies (SNS), headquartered in Stockholm, Sweden but with a 30-country-strong membership, according to its website.

Centering on the case of Sweden, with its history of forestry and timber exports, Lundmark starts by discussing the economically profit-bearing aspects of forestry. Timber and renewable energy production both bring revenue to an important business sector and prop up the Swedish economy.

He goes onto billing production of bio-based (or “green”) chemicals as having a beneficial social impact; along with forests or forested areas set aside for recreation or tourism activities.

Biodiversity and its protection and the forest’s capacity to act as a carbon sink, are among environmental considerations, he holds.

All these aspects should be included in a total analysis, according to Lundmark; for any estimates of appropriate trade-offs between the different areas to make sense.

“This is existing knowledge put in a different perspective… It is a balancing act to arrive at an optimal utilisation of forests. We need to consider all societal values or we can easily go wrong”.

Role of science, politics, markets

He stresses, however, that the role of science is to provide assessments and that of politics to correct missteps due to market “failure”.

“A functioning market guarantees an efficient allocation of forest resources. That is how it works in the trading of goods and services. The role of politicians is to correct market failures, for instance in cases where forest owners are not paid for preserving all benefits of the forest. That is why we highlight the discussion about internalising the cost of goods and services”.

A quick check of the Oxford Languages gives that to internalise in an economic sense, means to incorporate costs as part of a pricing structure, especially social costs resulting from the manufacture and use of a product.

Forests as a carbon sink

The assessments that scientists do are still important, because any attempts at cutting greenhouse gases must be cost efficient, according to Lundmark.

“We see that compensation would be required for change to be made on a large scale. Today forest owners are not compensated for leaving the trees in the forest” to promote longer rotation periods.

He says that the starting point is to recognise that forests and their trees are a finite resource and one that becomes more and more in demand along with economic growth.

“It is undeniably a complex debate with many dimensions to account for: Forest management, ecology, social and economic aspects and technical aspects. All of them must come into consideration when we estimate benefits and trade-offs”, Lundmark said.

Inventions by Bio4Energy Researchers Highlighted by Royal Academy for Future Potential

Zeolite membranes for gas separation, vertical gardens and reuse of textiles to make composites. These are subjects of collaboration projects by Bio4Energy researchers who have made this year’s 100 List hosted by the Royal Swedish Academy of Engineering Sciences (IVA).

To make the List, it takes a research project deemed to have “great potential to be useful”. This usefulness is thought of as potential for commercialisation of the product or concept studied, for development of either business or methods, or for providing thought leadership.

Another key criterion is for the project leader or researchers on the project to have expressed interest in collaborating with industry or related entities to further develop their invention.

Membrane technology for gas separation in use, tends to be bulky, energy intensive and cost a lot. Bio4Energy researchers Jonas Hedlund and Liang Yu are perfecting and developing ultra-thin zeolite membranes that take up less space and use less energy to perform the separation. These membranes would provide a large cost reduction if rolled out on a large scale, according to the scientists.

With Vertisà Ltd, Rosario García-Gil and team propose a module vertical garden that can be added onto the exterior of a house and mimics a natural ecosystem. Complete with a built-in watering system, which has been patented, it is not only designed to help with greenhouse gas capture in cities, but also serves to insulate and beautify the wall it is attached to. The module is both low-technology and low cost, according to the project leader.

A new process has been invented, which allows for reuse of scrapped textiles as a component in a new, strong type of composite material based on a mixture of discarded textiles and plastics. Kristiina Oksman and co-workers used a piece of process equipment called extruder, to mix the cut fabrics with plastics. The resulting composite is two fifths textiles and costs less than the standalone plastic polymer.
