Singapore's sustainable/organic plant fertiliser
ReRootSG:
Singapore's 100% organic plant fertiliser, made from upcycled food waste.
Active contributor to SG 35 by 35 goal through sustainable business practices.
For every 1kg of ReRootSG used,
1.5kg of food waste is rescued
from the landfill.
FROM FOOD WASTE TO FERTILISER
Better for plants.
Better for our planet
We transform everyday food by-products into 100% organic plant fertiliser, creating a positive impact at every step.
THE PROBLEM
Food waste
is a growing issue.
Singapore generates approximately 817,000 tonnes of food waste a year. At the current rate of 2,000 tonnes of waste per day, Singapore's Semakau Landfill is expected to reach capacity by 2035, which is roughly 11 years from now, if no changes are made.
Food waste does not just fill landfills,
It also emits greenhouse gases
as it decomposes.
SO, WE DID THIS...
Upcycle waste.
Nourish life.
At ReRootSG, we valorise food waste to create cost effective and nutritious plant fertiliser, without compromising on quality.
