Potential of bioethanol as a chemical building block for biorefineries
Preliminary sustainability assessment of 12 bioethanol-based products
The aim of this study is to present and apply a quick screening method and to identify the most promising bioethanol derivatives using an early-stage sustainability assessment method that compares a bioethanol-based conversion route to its respective petrochemical counterpart. ...
Innovations in papermaking
An LCA of printing and writing paper from conventional and high yield pulp
Pulp and paper industry is facing challenges such as resource scarcity and greenhouse gas (GHG) emissions. The objective of this research is to investigate whether the use of new coatings (micro or nano TiO2) and different pulp types could bring savings in wood, ene ...
Sustainability assessment of novel chemical processes at early stage
Application to biobased processes
Chemical conversions have been a cornerstone of industrial revolution and societal progress. Continuing this progress in a resource constrained world poses a critical challenge which demands the development of innovative chemical processes to meet our energy and material needs ...
Large appliances are major power consumers in households of industrialized countries. Although their energy efficiency has been increasing substantially in past decades, still additional energy efficiency potentials exist. Energy policy that aims at realizing these potentials ...
Transitioning towards a sustainable energy system requires the large-scale introduction of novel energy demand and supply technologies. Such novel technologies are often expensive at the point of their market introduction but eventually become cheaper due to technological lear ...
Twisting biomaterials around your little finger
Environmental impacts of bio-based wrappings
Background, aim, and scope: Packaging uses nearly 40% of all polymers, a substantial share of which is used for sensitive merchandise such as moisture-sensitive food. To find out if bio-based materials are environmentally advantageous for this demanding application, we compare ...
Petrochemicals from oil, natural gas, coal and biomass
Production costs in 2030-2050
Methane, coal and biomass are being considered as alternatives to crude oil for the production of basic petrochemicals, such as light olefins. This paper is a study on the production costs of 24 process routes utilizing these primary energy sources. A wide range of projected e ...
High costs often prevent the market diffusion of novel and efficient energy technologies. Monitoring cost and price decline for these technologies is thus important in order to establish effective energy policy. Here, we present experience curves and cost-benefit analyses for ...
Non-energy use of fossil fuels and resulting carbon dioxide emissions
Bottom-up estimates for the world as a whole and for major developing countries
Steam cracking and methane to olefins
Energy use, CO2 emissions and production costs
While most olefins (e.g., ethylene and propylene) are currently produced through steam cracking routes, they can also possibly be produced from natural gas (i.e., methane) via methanol and oxidative coupling routes. We reviewed recent data in the literature and then compared t ...
Non-energy use and related carbon dioxide emissions in Germany
A carbon flow analysis with the NEAT model for the period of 1990-2003
Olefins from conventional and heavy feedstocks
Energy use in steam cracking and alternative processes
Steam cracking for the production of light olefins, such as ethylene and propylene, is the single most energy-consuming process in the chemical industry. This paper reviews conventional steam cracking and innovative olefin technologies in terms of energy efficiency. It is foun ...
