Comparing two materials and justifying my 昀椀nal material choice
Compare the environmental impact of two different fertilising, carbon-capturing materials for a vessel or sculptural shape, that enhance plant growth.
Identifying the most sustainable material ( focus on fertilising aspect ) and opportunities for improvement.
Material 2
Biocharged ( colofonia/urea )
(Final) Material
1 Biocharged ( cornstarch/ urine )
consists of biochar made from urban
greenery waste, water, synthetic urea, colofonia
and corn starch
Production ( similar ) and Transport ( equal )
consists of biochar made from urban greenery waste, cornstarch, water and human urine as a fertiliser
Material extraction major focus
Environmental Impact Categories
Global
warming ( CO2 )
Terrestrial Acidi昀椀cation
Biochar and Urine and wood residues for fuel
are waste material and do not count in database
Choice based on urea and urine as water and land polluter
Fresh Water Euthropication
Water
Consumption
Biochar/Biowaste for Material 2 I calculated 1kg of Biowaste as a
source material to see its impact.
12 km
14 km
Transport and collection
for biochar
= equal for both materials
2.2 km
