The reconstruction of second-hand furniture and scrap metal : inspired by the architectural structures of deconstructivismPietersen, Melanie January 2010 (has links)
Thesis (BTech (Surface Design))Cape Peninsula University of Technology, 2010 / The purpose of this research is to explore and create an understanding of how
architectural structures. that adhere to deconstructivist design principles, can
inspire the reconstruction of second-hand school fumiture and scrap metal. The
planned pieces will continue to create an awareness of sustainability, by designing
for reuse. These functional fumiture pieces of low tables and chairs will be
handcrafted, appealing to a niche market, or specific spaces and they will act as
expressions of contradiction.
This research will act as an addition to a body of knowledge, where I will primarily
focus on contradicting the traditional form and aesthetic of furniture design. I have
decided to create these functional pieces to express a new possible direction of
furniture design.
The study context is a potential confrontational experience in that I want to
challenge the conventional form and aesthetics of fumiture design. These pieces of
fumiture will be placed in a niche market where they will exist as one-offs that are
not produced for mass-consumption, as they will be individually hand-erafted.
These days more and more people are attempting to live in a more sustainable
manner by practicing to reduce our consumption of products and resources; reuse
that which we have disposed of and forgotten as consumers and to recycle waste
products and transform them into a feasible afterlife (Martin, 2010).
The theory is focused on Sohaill Inayatullah's theory of "Futures Thinking", and this
.theory is further supported by Victor Margolin's study of changing existing
situations into preferred ones. The research further reflects on Jacques Derrida's
theory of deconstruction, and this research is further supported by the theory of
sustainability, by designing for reuse, with a focus on Ezio Manzini.
Therefore, my research study is concerned with confronting and challenging
the conformity that the form of furniture and its aesthetic adhere to.

EVOLUTION OF SMARTPHONES METAL CONTENT WITH ITS FAST-IMPROVING FUNCTIONALITIESOmar N Tantawi (9187403) 31 July 2020 (has links)
<p>Smartphones, one of the most common consumer
electronic devices, are an essential part of daily activities in modern
society. Smartphones provide faster communication, easier access to information
and many other important services. However, with a compressed product life
cycle and growing consumer demand, a significant number of smartphones reach
End-of-Life (EoL) annually. At the same time, due to many special physical
properties, rare earth, critical and other important metals are essential for
the manufacturing of smartphones. Hence, from various economic, resources
availability and environmental perspectives, it is crucial to understand how
metal content of different smartphones generations change over time. To this
end, a high production smartphone series, produced between 2010 and 2015 were
considered in the scope of this study. The devices were disassembled, sorted
into different components and size reduced. Printed circuit boards assembly,
back cameras and NFC antenna/wireless charging chips were then digested using a
novel microwave assisted acid digestion method. Inductively Coupled
Plasma-Optical Emission Spectroscopy was used to detect and quantify 60
elements. Obtained results indicate that up to 70% of different smartphones
components by weight are important recyclable metals. The highest concentration
elements, Cu, Ni, Sn, Zn and Fe, accounted for 93.3% while REEs and PGMs
collectively accounted for 0.53% of the total recoverable elements by weight.
In 2019, the total addressable market value of metals reclamation from only
three smartphone components at their end of life is estimated at 298.69 million
USD in USA. Gold and Platinum were determined to be the most environmentally
critical elements and efforts should made to reduce their use. Finally, and
most importantly, smartphones manufacturers should design their products with
an extended lifetime due to the high concentration of critical elements used to
make them.</p>
