Detta projekt undersöker de ekonomiska, tekniska och miljömässiga aspekterna avtextilproduktion samt textilåtervinning. Paralleller dras mellan olika naturfibrer ochsyntetfibrer där såväl positiva som negativa aspekter belyses. I rapporten exemplifieras demest omdiskuterade textilierna; bomull, polyester, viskos och lyocell. Vidare görs en analyspå diverse textilåtervinningstekniker som finns i dagsläget och hur dessa är lämpade fördagens samhälle. På så sätt kan man undersöka vilka framtida möjligheter och begränsningarsom finns för utvecklingen av den textila återvinningen. En SWOT-analys ut

Abstract:

This master thesis studies the recycling prospects of textiles. The textile industry contributes negatively to the global environmentthrough the release of greenhouse gases and consumption of resources. In order to achieve a circular textile industry, textiles must be recyclable by both chemical and mechanical means. Here, the focus is on mechanical extraction of staple fibres, particularly cotton, for reentry into yarn production. Experiments show that used, but undamaged, cotton sateen and cotton twill responds differently to abrasion with stochastic surfaces. Previous studies on the convent

The methods investigated for removing the binder from E-glass fibres were: (i) fibre spreading; (ii) acetone-based treatment; and (iii) heat treatment in air and in a vacuum. In the first phase of the research, the effect of the above mentioned binder removal methods were investigated using the single-bundle tensile test. Binder removal via fibre spreading did not cause any reduction in the properties of E-glass fibre bundles

Abstract:

The thesis focuses on the improvement/enhancement of energy efficiency of the machine; called Granu-lator of the recycling process of polythene. In the recycling process, it is observed that energy is wasted unnecessarily, and thus energy efficiency must be improved. The reason is that the granulator has been operating with an old rotor. Therefore, the introduction of a new rotor to the main Granulator and im-provement of the energy consumption must be done simultaneously. The energy consumption to pro-duce a unit mass of useful output was calculated for the main Granulator with the old rotor.

Abstract:

There is a growing need for fibres with increasing population. One way to solve this is to recycle the fibres from textile waste. In mechanical recycling by shredding the textiles are shredded back to fibrous form. The biggest problem with shredding is that it is a harsh process that reduces the fibre length and damages the fibre. To make the shredding process more gentle and preserve more of the fibre length, pre-treatment that lowers the friction between the fibres have been investigated.

Abstract:

Nowadays, when environmental concerns are becoming increasingly important are there great interest in natural materials and recyclability. The possibility of reusing materials with maintained mechanical properties are essential for sustainability. Today produced approximately 90,000 tons of natural fiber reinforced composites in Europe of those are 40,000 tons compression molded of which the automotive industry uses 95%. Natural fiber reinforced composites is recyclable and therefore interesting in many applications. Also, natural fiber reinforced composites is inexpensive, light in weight and

Abstract:

The use of plastic materials has changed the packaging industry, the construction industry, the automotive industry, and many others drastically. Plastics are also abundant in our everyday life. However, its downsides in the society are undeniable and are starting to get attention from law makers, the general public and industries alike. Because of their reliance on fossil feedstock and persistence in nature, efforts are being made to make plastics biobased as well as improving recycling of the material. However, the recycling process is complicated, unoptimized and also differs depending on t

Thesis (MScEng)--Stellenbosch University, 2011.<br>ENGLISH ABSTRACT: A major challenge for our society is the protection of the environment. Some of the important issues are the reduction in the consumption of energy and natural raw materials, as well as the increase in consumption of waste materials. At present these topics are getting considerable attention as part of sustainable development programs. The use of recycled concrete aggregates (RCA) from construction and demolition waste (C&DW) in construction, as alternative to virgin (natural) aggregates, has strong potential. The use of

Abstract:

Polyethylene terephthalate (PET) is the most used fibre in the textile industry. PET is also used in other products, e.g. soft-drink bottles and food packaging. Approximately 60% of the globally produced PET is intended for production of textile fibres and the demand for polyester fibres have steadily increased over the last decade. Yet, most of the recycled PET fibres are produced from discarded bottles and not discarded textiles even though the generation of textile waste is increasing year by year. The importance of finding efficient recycling routes for discarded PET textiles is obvious. I

Background Tarkett AB Ronneby (Sweden) is a flooring solutions company, recognized for the manufacturing and recycling of homogeneous plastic flooring. Tarkett AB recycles mainly installation spill and manufacturing defects. However, Tarkett AB is considering widening its recycling capabilities to include old and torn plastic floors which may contain impurities and banned substances or plastic floors of competing brands. To accomplish this, Tarkett is considering a completely new recycling line with an automated sorting process instead of the current manual process. Thus, Tarkett proposes a di

Abstract:

Waste is a problem that is more relevant now, in the 21st century, than ever before. Waste management is becoming more crucial with more people moving into cities, which demands a fast lifestyle and leading to massive amounts of waste. Managing all the generated municipal solid waste is putting huge amounts of pressure on the infrastructure. Zero-waste is a topic that has gained popularity as environmental issues have gained attention. The topic has only been around since the late 1990s and without an official governing body the meaning of the topic is diffuse. The research objectives of thi

Abstract:

Oggigiorno, la produzione di conglomerati con elevate percentuali di fresato (RAP) rappresenta una delle maggiori sfide da affrontare. L’inclusione di RAP garantisce vantaggi in termini ambientali ed economici, soprattutto tramite riciclaggio a caldo, tecnica che permette il simultaneo sfruttamento della fase bituminosa e lapidea di una miscela. Attualmente i quantitativi di RAP comunemente utilizzati sono limitati data la mancanza di esperienza e di prove scientifiche che dimostrino la possibilità di includere fresato senza penalizzare le prestazioni della pavimentazione.
