Not Crop-Based / Not Cellulosic Benefits to PartnersFermentation-Ready
Proterro makes low cost sucrose that unlocks
economical production of biofuels and chemicals
We Make Sugar…
Avoids pricing volatility Predictable, reliable
source of production Much less land vs crops 1/10 water of algae
systems
Drop-in sugar feedstock No further processing
required for fermentation to biofuels/biochemicals
Easily scalable
Complements 1st and 2nd generation ethanol
Clean sucrose (no other sugars or inhibitors for biochem)
Monetizes CO2
To supplement sugars extracted from crops or deconstructed from cellulosic materials
The Feedstock Challenge
3
Corn and Sugar
Access to a reliable, low-cost feedstock remains a critical barrier to scale
for the production of bio-based fuels and chemicals.
Feedstock Challenges
Price Volatility: Seasonally- and market-driven price
volatility
Food v. Fuel: Land competition
Biomass Availability: Access to amount of biomass
required to obtain economies of scale is limited
Biomass Recalcitrance and Non-Homogeneity:
Fractionation and deconstruction of biomass into usable
intermediates require complicated and expensive multi-
step processes
Cellulosics
Proterro addresses these challenges by making affordable, fermentation-ready sucrose

Proterro Patented Process
Path to Commercialization
1. Lab scale development and proof of concept
2. Greenhouse Testing
– 1/3rd m2 photobioreactor; 3 months
3. Pilot Program – Orlando, Florida
– Outdoor testing in natural light; 50 m2 growth surface per bioreactor
– 4 months continuous operation
– Consistent and controllable sugar production
– No contamination effect on sucrose productivity
– Results verify process is scalable
4. Demonstration Program– Outdoor testing adjacent to mill or other CO2 source
– ~100 photobioreactors working as a system
5. First Commercial Plant
