Raw Material Supply and its Influence on Profitability and Life-Cycle Assessment of Torrefied Pellet Production in Finland – Experiences from Pilot-Scale Production
(Lappeenranta-Lahti University of Technology LUT, 2021-11-05)
The European climate policy aims to move toward an environmentally friendly world, and it has been awakened by a strong will to find replacement fuel alternatives to fossil fuels, especially for coal. Torrefied pellets ...
Transition towards optimal renewable energy systems for sustainable development
(Lappeenranta-Lahti University of Technology LUT, 2021-11-04)
The world is in transition from current fossil fuel-based decoupled energy sectors, towards defossilised and integrated energy systems. Debates on such a transition, initially inspired by fossil fuel scarcity concerns, ...
Analysis of sorption-enhanced gasification for production of synthetic biofuels from solid biomass
(Lappeenranta-Lahti University of Technology LUT, 2021-12-01)
Anthrophonic greenhouse gas emissions have led to climate change. The transportation sector is one of the most significant greenhouse gas emitters. Mitigation of carbon dioxide (CO2) emissions from transportation is a great ...
Transition towards decarbonised power systems for sub-Saharan Africa by 2050
(Lappeenranta-Lahti University of Technology LUT, 2021-05-25)
Globally, power systems are undergoing significant structural changes, spurred primarily by declining cost of renewable energy technologies, changing demand patterns, energy security concerns, increasing scarcity of fossil ...
Assessment of agro-forest and industrial residues potential as an alternative energy source
(Lappeenranta-Lahti University of Technology LUT, 2021-05-11)
The generation of energy from alternative and renewable sources is of enormous importance for the sustainable development of the world bioeconomy, as its use mitigates environmental issues such as greenhouse gas emissions. ...
Transforming the chemical pulp industry : From an emitter to a source of negative CO2 emissions
(Lappeenranta-Lahti University of Technology LUT, 2019-10-18)
The chemical pulp industry is an energy-intensive industrial sector. Modern kraft pulp mills are typically energy-independent, and fossil fuels are used mainly in lime kilns. Following the Paris Agreement, the pulp industry ...
The role of efficient forest biomass logistics on optimisation of environmental sustainability of bioenergy
(Lappeenranta-Lahti University of Technology LUT, 2020-06-17)
Forest biomass is a crucial element in the energy system in many parts of the world, especially in Finland, and it is expected to play a similar, if not a more important, role in the near future as countries aim to replace ...
The role of the forest industry in mitigating global change: towards energy efficient and low-carbon operation
(Lappeenranta-Lahti University of Technology LUT, 2022-10-21)
The forest industry has increased its energy efficiency substantially in the 21st century, but higher improvement rates could be expected regarding targets set by the European Union and the Intergovernmental Panel on Climate ...
Global climate as a commons — from decision making to climate actions in least developed countries
(Lappeenranta-Lahti University of Technology LUT, 2022-12-09)
The international battle against climate change requires action from all parties of the United Nations Framework Convention on Climate Change including the rapidly developing low-income countries. Most of the least developed ...
