, 2013 Norway spruce Picea abies is a key raw material for the forest industry in the Nordic countries. In order to improve the competitiveness of the forest industry by valorising residues and creating value from new products, we have studied the upgrading of spruce bark into transport fuels and chemicals.

Performance of Glass Fiber Composites With Plastic‐Waste Pyrolysis Char as Filler
Polymer Composites, EarlyView.Valorisation of mixed plastic waste into carbonaceous char via pyrolysis, its integration as a microfiller in epoxy/E‐glass (GFRP) laminates, and characterisation to assess composite performance as a function of filler loading. ABSTRACT Plastic pyrolysis offers circular solutions for mixed plastic waste but leaves a carbonaceous char that is often ...

Effects of Multiple Mechanical Recycling Loops on the Material Properties of Liquid Silicone Rubber
Polymer Engineering &Science, EarlyView.Mechanical recycling of liquid silicone rubbers was investigated by grinding LSR production waste to small pieces, which are then used as filler in new products with varying percentages of recycled content. Four consecutive reprocessing cycles showed that multiple mechanical recycling loops are possible without significant loss of material performance.

Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska
Permafrost and Periglacial Processes, EarlyView.ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

Permafrost and Periglacial Processes, EarlyView.ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

Two "Fires" of Leadership: Is it Possible to Listen and Lead Parish Cultural Change?
Journal of Moral TheologyPope Francis has claimed that “we are living through a change of epoch, the deepest level of which is cultural.” “A change of epoch” entails much change in Catholic parishes especially across the Western world. Change can be chosen or unchosen.
