Urea
Calcium Carbonate
Urea is a synthetic fertiliser and also a residue in our urine. Urea
is an important molecule in nitrogen recycling and translocation Test if calcium carbonate can bind Biochar into a ceramic-like
material that captures carbon and has a mineral/fertilising effect
in plants
on plant growth.
Due to its high concentration of nitrogen, it is essential that the
ratio is controlled to avoid nitri昀椀cation, volatilisation and leaching (enzyclopedia)
in crop yield. (Rychter, Naz F. )
Starch
Urine
Use of cornstarch is as a byproduct of agricultural activity. Corn
starch is an organic polymer, a natural polysaccharide which binds Urine is an abundant waste material that consists of 95% water
well with water biochar and enhances nutrient intake. It is easily and major nutrients such as Urea, potassium, and phosphate. The
amount of Urea is small, which, in combination with a binder,
accessible and non-toxic to use.
doesn’t affect the mix of material. Yet Biochar takes nutrients in

Clay/Soil
Mycellium
Depending on many factors, soil varies in quality and character- When charged with nutrients (urine ), biochar gives food and
istics. For the experiments, I used local soil from El Prat, which is space for microorganisms, fungi and bacteria; testing the growth

Alginate
Agar
It is a polysaccharide that is a super absorbent polymer. Testing

in alginate polymer matrix soil quality and plant nutrition can
improve.
This binder is very expensive for higher amounts and, in the
context of circular stakeholders, would be implemented more in
wastewater management and sorption than in the agricultural

Agar is a polysaccharide-based hydrocolloid seaweed with signi昀椀cant gelling ability. Great binder.

Colofonia
Cellulose / Paper Pulp
Side Product of the agroforest industry and used in the paper and adhesive industry.

Use of recycled cardboard and paper as well as straw and grass to
mix with Biochar to bring it into certain shape.
