MATERIALS & MANUFACTURINGMaterials are of foundational importance for our technological society. Particularly in these times, when we are
challenging huge environmental issues like climate change, it is of paramount importance to be aware that use
of materials has a crucial environmental impact. In order to reduce our material footprint, we will have to work
more and more with recycled materials and one way of doing so is utilising materials that we extract from waste
streams.
The core of the M&M course is designing new products made of waste materials such as fruit waste, wood chips,
starch and/or any other bio-based materials. E.g. why not use a starch-based or fruit-based material to make an
edible lunch box, or design your own bio-based cover for your tablet? Why not use a wood chip mixture to make
something for daily utensils as a replacement for unsustainable polymeric ones?
The key objective of the course is to teach you how to use bio-based materials in this concept. This implies that
you need to look at relevant properties for production and use. E.g. mouldability or shaping limits; properties
such as strength, stiffness and durability, but also paying attention to aspects of users' evaluations. You will also
learn how to test material properties, and how to design a sample product taking into consideration these
properties. In this course, we envision our contribution to shaping a green future, starting with creating a
growing awareness about the materials that we use for manufacturing daily products.
Every week on Monday there will be an announcement for the plan and agenda of the coming week, both
lecture and workshop. Please read the announcements thoroughly.
,WEEK 1 KICKOFF COLLEGE
M&M KICKOFF NO PLASTICS – ERIK THOMASSEN
METAL WORLD TO A PLASTIC WORLD
Vroeger werden de meeste producten gemaakt van metalen.
Aan het einde van de WO2 werd de wapenindustrie omgezet
naar consumptie-industrie. Plastic werd veel gebruikt toen om
producten te maken. Er was in die tijd heel veel plastic, en
ontwerpers gingen ermee experimenteren wat ze er allemaal
mee konden doen. Zo is plastic makkelijk te vervormen en te
verkrijgen in complexe producten in verschillende kleuren. Dit is
modieus en betaalbaar en was in die tijd helemaal geweldig.
Plastic wordt momenteel als wegwerp gezien doordat het
goedkoop is en simpel te vervormen. Ook weinig hitte nodig om
te vervormen wat dus weinig energie nodig heeft vergeleken
met andere materialen. Ook is plastic super licht.
In producten worden hedendaags
heel veel verschillende soorten
plastics gebruikt en ook
samengesmolten waardoor niet te
recyclen en dus belastend voor
milieu.
- Milieuvervuiling
- Niet te recyclen, dus steeds nieuwe
grondstoffen nodig waardoor
grondstoffen op raken.
Daarom van de lineaire economie een
circulaire economie maken waar
grondstoffen worden gerecycled en
hergebruikt voor nieuwe producten.

‘Truth is: we do therefore I become’
Thinking begins in Doing and Thinking begins being a-
conceptual
Making is Thinking; How Doing Transforms Innovation
Doing research and preparing doesnt let de activity work
in one time, het zal altijd anders verlopen dan waarop je
bent voorbereid
Proberen komt voor studeren; just do it

M&M KICKOFF LECTURE – SEPIDEH GHODRAT
Climate change is highly materials related. Our material footprint is important, an indicator reflecting actual
consumption of raw materials!
Materiaalkeuze in producten heeft namelijk te maken met de grondstoffen die op aarde te vinden zijn. Verder
moeten materialen ook worden bewerkt om producten van te maken, en dit hele productieproces en hoeveel
energie hierbij nodig is en hoeveel uitstoot het veroorzaakt is materiaal afhankelijk.
Bio-based material → Is a material derived from the living (or once-living) organisms like feedstock including
corn, sugarcane, organic polymers which can be degraded in the environment in one year.
Bio-based products are goods made from renewable biogenic material (also called ‘biomass’). The most
frequently used types of biomass are sugar, starch, plant oils, wood and natural fibers.
Voor bio based producten kan je
natuurlijke grondstoffen verkrijgen
uit de natuur. Echter kom je hier
met het dilemma of je het product
duurzamer maakt of dat je
eten/voeding voor andere
organismen afpakt.
Daarom is het interessanter om te
kijken naar producten gemaakt uit
voedselafval van de mens. Dit afval
zou anders gewoon worden
weggegooid, dus heeft geen ander
doeleinde.
Biodegradeerbaar → Een biodegradeerbaar product kan worden afgebroken door micro-organismen.
Bio-based → ‘Biobased’ zegt iets over de oorsprong van een materiaal. Het duidt op materialen die gemaakt zijn
van hernieuwbare grondstoffen en compleet of gedeeltelijk bestaan uit biologische materialen- zoals vezels,
suiker (s), micro-organismen, of eiwitten.
- Bio-based materialen zijn materialen die afkomstig zijn uit de levende natuur.
