Master's thesis

Abstract:

Nothing is permanent and doesn't exist on earth without having a change. If we think about the history, we see there was an end of everything. Something new appears and replace the old one. Every problem is bound with a solution. Earth is changing every day and losing the balance from many sides where environment is one of them. To keep the balance equal and friendly something unique must be invented. Green roof is one of that kind. It's an invention which belongs to the group of nonwovens. It's a process which is creating several things for the society also creating several needs. Amount of our basic needs are increasing day by day as well as the demand of textile industry. But it's not unknown that the increasing amount of textile industry causing pollution. To prevent this the concept of sustainability is growing. Sustainability in nonwovens is one of them. Zero waste materials, green manufacturing, less production of carbon by keeping the low impact are turning it into more sustainable. Due to the alarming environmental impacts such as climate changes in a drastic way, extreme hot & cold temperature as well as unpredictable climate sustainability are getting more attention. Sustainability became inevitable in the industry of manufacturing. This thesis is about to create an aquadesk board which can be used as a base or vegetation board in green roof. It also plays a good role in sustainable nonwoven industry. To create this product there would be no use of chemicals which can impact badly on environment. So, it's an eco-friendly product which can be prepared by using 90% of recycled materials . It's also used as a vegetation board of green roof which can absorb water from rain and any other sources and hold it to use when necessary. The main aim of this diploma thesis is to develop the water retention properties. We must focus on increasing the water retention properties of the new sample. This diploma project will be studying and understanding on this topic.
