From an environmental challenge to a great opportunity
A biotechnology platform for the comprehensive valorization of agro-industrial waste.
Agro-industrial waste contains value
But today it is a challenge, and it must first be stabilized and transformed:
High organic matter load
Odor generation
High moisture content
Handling and recovery costs
But they all have something in common: they contain value.
GRAM answers with a platform, not an isolated solution
Proprietary bioprocesses and a circular bioeconomy to capture the carbon, minerals, molecules and energy that are lost today.
Agro-industrial waste
Solid, paste-like or liquid (including vinasse).
GRAM aerobic bioprocess
Submerged fermentation
In air-lift bioreactors
Solid-state fermentation
For solid and paste-like streams
Bioactive molecules
New high-value raw materials
Sustainable energy
Renewable fuels
New materials
Fertilizers, biomaterials and other products
Vinasse
A waste stream with a high organic load, unstable and complex to handle. This is where we truly differ: we do not stop valorization at a single output.
- 1
Vinasse
Liquid waste stream
- 2
Stabilization
Organic matter control and no further gas generation: we make it safe to handle and transport
- 3
Concentration
Without fossil energy, raising the content of high-value carbohydrates
- 4
Aerobic fermentation
Submerged and solid-state
- 5
ECO2GRAM
New biotransformed material
- 6
Enzymatic hydrolysis
Molecular transformation
- 7
GR314
Purification of new bioactive molecules
20 °Brix → 85 °Brix
Concentration without fossil energy consumption
ECO2GRAM: biotransformed material rich in high-value carbohydrates (80% rhamnose and sophorose, 20% sucrose).
And here the platform opens into multiple valorization routes:
Bioactive molecules
GR314 → new bioactive molecules for high-value applications.
New valorized vinasse
Sucrose + minerals + bioactive molecules.
Blending with waste
Nutritional additives • fertilizers • renewable fuels.
One waste stream → multiple valorization routes.
Molecular transformation and multiple products
Vinasse valorization does not end in a single output.
Bioactive molecules
GR314 → high-value products for applications in health, agriculture and productive environments.
Sustainable energy
Energy valorization routes for biomass.
New materials
Biotransformed raw materials and materials.
Nutritional additives
Animal-science solutions for multiple species.
Fertilizers
Valorization of minerals and organic matter in formulations; agronomic use of nutrients.
Renewable fuels
Valorized and enriched solid biomass with high energy value.
One waste stream → multiple valorization routes → multiple value opportunities.
The platform adapts to the waste stream and the target product.
Bio-drying and enrichment with no energy consumption
A real case of bio-drying and energy enrichment of agro-industrial biomass.
74.20% → 6.14%
Documented moisture reduction
20,000 t/year
Sized industrial scenario
11.97 million L
Water removed, recovered and reused
1.24 MWh/t
Energy produced per tonne of initial waste
5,987 t
LPG consumption avoided
1,996 t
CO₂e emissions avoided

- 2 Characterize
Composition, moisture, organic load, energy potential and transformation possibilities.
- ✓ Physicochemical analysis
- ✓ Moisture determination
- ✓ Organic load
- ✓ Energy potential
- ✓ Identification of valorization opportunities
- 3 Develop
GRAM designs the biotechnological valorization route.
- ✓ Process design specific to the waste stream

- ✓ Definition of products and valorization routes
- ✓ Techno-economic and environmental assessment
- 4 Pilot
Proof of concept under representative conditions.
- ✓ Pilot execution
- ✓ Validation of operating parameters
- ✓ Assessment of technical, environmental and economic results
- ✓ Adjustments and optimization
- 5 Scale up
Industrial implementation through the corresponding technology option.
- ✓ Design and engineering of the industrial solution
- ✓ Installation and commissioning
- ✓ Technology transfer and training
- ✓ Performance monitoring and continuous improvement
Environmental, technical and economic value
Technology must deliver value in all three dimensions.
Valorization
Turning waste into higher-value raw materials and products.
Energy
Energy recovery routes and renewable fuels.
Resources
Recovery and reuse of water and other components, depending on the stream.
New products
Bioactive molecules, additives, fertilizers and new materials.
Less fossil dependence
Processes designed to self-generate their activation energy without fossil fuels.
New opportunities
Turning a residual cost or liability into a new business opportunity.
From an existing waste stream → to a new value opportunity.
The specific outcome is determined for each stream through characterization, piloting and techno-economic assessment.
Give us a waste stream.
We will turn it into value.
