sustainability
no adjectives on this page; a cycle and a measurement plan instead. we do not write “low energy” or “zero waste” without measuring.

01cycle
five products from a skin taken for waste.
seed to fieldfield to tomatotomato to pastepaste to skin
- 01

tomato skin
the skin left over from tomato paste, usually seen as waste.
- 02supercritical CO2

lycopene
from the skin, by supercritical CO2 extraction.
- 03

spent skin
the skin without its lycopene, raw material for the next step.
- 04

plant protein
from the spent skin, by biotechnological means.
- 05

tomato skin fibre
from the spent skin without lycopene and protein.
- 06


bread and bioplastic
from fibre to bread; from fibre to bioplastic.
supercritical extraction is the first link in this chain: it takes the lycopene from the skin and leaves the spent material as raw material for the next step.
02measurement plan
what we will measure.
- energy
- electricity and heat used per kilogram of product. proposal
- CO2 loop
- the CO2 used in the system is recovered and reused. the amount of CO2 topped up per batch will be measured at serial production. brand statement
- raw material yield
- extract obtained per kilogram of plant material. proposal
- spent material
- where the spent plant material goes; the aim is for it to become raw material for the next product, as in the tomato example. proposal
03sourcing
side streams can be a raw material.
some raw materials, such as pomegranate and grape seed, can come from another production's side stream. where each raw material comes from is written in the batch record; side-stream use will be shown here once documented.
