11 12 The biological treatment of spent synthetic metalworking fluid (MWF) has been investigated in many studies, 13 with most reporting the presence of un-degraded components in the residual waste. In this study, we 14 investigated a hybrid approach to waste treatment of spent MWF, involving both physical treatment and 15 microbial degradation. The effect on biological degradation, of the remo...

variety of polymeric materials were developed as the basis for sequestering and sensing ions in aqueous solution. Polymers were made that can act as selective ion exchange resins. The selectivity can sometimes be made to approach exclusivity and allow the simultaneous removal and purification of a variety of chemicals. This approach can be used to turn waste streams of hazardous chemicals into ...

The effective waste heat recovery is one of the present-day challenges in the industry and power engineering. The energy systems dedicated for waste heat conversion into electricity are usually characterized by low efficiency and are complicated in the design. The possibility of waste heat recovery via thermoelectric materials may be an interesting alternative to the currently used technologies...

This study analysed the dissolution phenomena of plastic polymers into biodiesel through experimental measurement. The effects of experimental parameters, such as temperature, concentration, agitation, time and feed rate, etc, when mixing two different polymers with biodiesel wereobserved to deduce trends that can be adapted into further exploration. Suchinvestigation is reasonably new in Austr...

The main motivation for development of biobased polymers was their biodegradability, which is becoming important due to strong public concern about waste. Reflecting recent changes in the polymer industry, the sustainability of biobased polymers allows them to be used for general and engineering applications. This expansion is driven by the remarkable progress in the processes for refining biom...

Biodegradable polymers such as polyhydroxybutyrate (PHB) are part of the emerging portfolio of renewable materials, which are addressing the issue of plastic waste. Syngas, as a cheap, renewable and sustainable resource that can be obtained from biomass or waste, is viewed as an excellent feedstock for different bioprocesses, including syngas to PHB bioconversion. However, due to the hazardous ...

According to different sources, from forty to sixty percent of the overall energy generated in the world today is squandered in waste heat. The existing energy conversion technologies are either close to their efficiency limits or too costly to justify their implementation. Therefore, the development of new technological approaches for waste heat recovery is highly demanded. The field of thermo...

In this work, the results of studies on the evaluation of colloidal structure of coal-tar pitch compositions with selected waste polymers by fluorescence microscope. For pitch-polymer compositions containing 10-50 wt% waste polymer, softening point, coking value and content of components insoluble in toluene and quinoline were carried out. The results indicate that pitch-polymer compositions ca...

Plastics have prominent utilization worldwide. Polyethylene Terephthalate (PET) is one of the major types of plastics that can be found in the Municipal Solid Waste (MSW) [1]. MSW contains high proportion of thermoplastic polymers which has been increasing in value. PET is a semi-crystalline thermoplastic polymer, and is considered as polyester material [2]. Large amount of waste PET is being p...
