Thermal stability is of major importance in polymer extrusion, where product quality is dependent upon the level of melt homogeneity achieved by the extruder screw. Extrusion is an energy intensive process and optimisation of process energy usage while maintaining melt stability is necessary in...

Polymer extrusion, in which a polymer is melted and conveyed to a mould or die, forms the basis of most polymer processing techniques. Extruders frequently run at non-optimised conditions and can account for 15–20% of overall process energy losses. In times of increasing energy efficiency such...

Purpose – The purpose of this paper is to present a methodology to improve decision making about investments that reduce buildings' energy consumption. Design/methodology/approach – A three‐stage methodology was developed and tested to analyse an existing Australian office building's...

The implementation of sustainable development in Romania and the abrupt increase of prices for fussil fuels have imposed more serious activies for the examination of the energy consumption in different industrial sectors. Here, the asynchronous electric m

The implementation of sustainable development in Romania and the abrupt increase of prices for fussil fuels have imposed more serious activies for the examination of the energy consumption in different industrial sectors. Here, the asynchronous electric motors represent the main loads; therefore...

Reducing energy demand and increasing energy efficiency are seen as major elements of the ongoing transformation of energy systems in multiple national and international programs like the EU 20-20-20 targets. Despite the predominately socio-economic nature of energy demand such interdisciplinary...

Consumers have become environmentally conscious, they are keen on energy efficiency and the increasing importance of the environmental values in general has made this research relevant. We analyse the special elements of eco-marketing so that we can see which are the tools and marketing...
