packaging Flashcards
function of packaging
contain protect transport preserve display inform
3 catergories of packaging
PRIMARY: basic uni, labeled, direct contact with the object
SECONDARY: box or crane and display/transport uni
TERTIARY: several bundles; transported by shipping containers for distribution
world wide material used for packaging
glass plastic aluminium paper board
why has food packaging increased
tech advances
pre-packaged food
the convenience of single-serving and ready meals
why is there so much packaging waste?
total mass has increased but recovery has unchanged
more than 1/3 of food packaging cannot be recycled as it is contaminated and/or unrecyclable
weak sustainability
environment, society and economy:
- are competing interests
- separate aspects of development
- tech as a substitute for a damaged environment
strong sustainability
environment as the priority/common ground for society and then economy
what is CSSDC
cyclic solar safe efficient social design
solar?
uses renewables
cyclic?
organic, recyclable, compostable
safe
non-toxic for humans and other chemicals
efficient
uses 90% less water/energy/matieral
social
protect human rights, health, livelihood, and communities
strategies for sustainable packaging?
design for reuse/recycling manufacture with renewable, compostable and recycled material eliminated toxic inks/paints, etc. eliminate secondary packaging reduce volume
types of composting?
home and large-scale (at 60c)
application of bioplastics, biocomposites, biopolymers
car coating and parts
eco-bags
textiles
agriculture
renewable material examples
cellulose film
bioplastics (from corn starch, potato)
paper/cardboard from sustainable forests
recyclable plastics
examples of reusable material
resealable plasticcontainers
return systems for custome refills
bulk buying
how to reduce the volume
inflatable pouches to fill package waste
lightweight bottles/cans
discuss BPA
starter polymer for plastic synthesis with health issues and hormones:
to reduce use bpa free/but cans/avoid heat and use alternatives
discuss LEAD
toxicity affects nervous system: causes issues anemia, hypertension, coordination issues
what is the future of packaging?
‘active and intelligent’ parcakaing that minotirs, freshness, detexts toxic environment, extends shelflife , etc.
ecocradle
fungi-grown sustainable sytrafoam
packaging policies/regulations
world packaing organizatio nfor sustainable reccomendations
european commission aims to reduce 70% by 2021
Ocean Clean up Project
biopolymers
produced by living organisms
i.e. chitin, starch, etc.
issues with paper/cardboard
cant be recycled indefinitely due to shortening fibres
often contaminated
can be home composted
metal material
steel/aluminium most common
relies on environmentally destructive mining
recycling needs sustainable energy to be recyclable
can be recycled always however without losing quality
glass material
very energy/water intensive
good storage material (olive oil, jams)
can be indefinitely recycled but MUST be colour separated
plastic as a matieral
many variations and internationally coding system
can be composed
PET (rigid plastic base for contaminant)
PS (expanded polythene for thermoregulation)
