The need for more sustainable treatment of organic waste streams is evident. Volumes are increasing and resources are depleting. In addition, we are starting to see how much environmental damage irresponsible handling of waste can cause. As a result of this, policies for how we gather and treat these waste streams are gradually becoming stricter.

Utilizing waste heat and producing biochar is good for the environment. However, sustainability is measured in impact, not virtue – it does not matter how environmentally friendly the technology is if no one buys it. We need responsible technology that does not sacrifice on either performance or cost. 

Introducing the Hellenes Bio-TTU

The Hellenes Bio-TTU enables fast, reliable, environmentally friendly, and cost efficient treatment of organic waste. The treatment is highly flexible in regard to dry matter content (15-95%), consistency, and heating value of the input. In addition, by utilizing waste heat as the main energy source, it can reduce CO2-e emissions by up to 60% compared to competing technologies. 

The Bio-TTU is the result of many years of R&D and testing. The key innovation behind our technology lies in how we combine capabilities from both indirect, and friction-based heating solutions. This is possible due to our patent pending method where we are able to increase the heat transfer substantially. The consequence of this is that we can transfer a higher amount of heat per square meter and thus make the unit smaller. Smaller units mean less cost and less complexity.

We offer two different treatment solutions for biomass: Drying and Pyrolysis 

Drying Applications

Thermally removing water from a substance requires high amounts of energy (around 0,8 kW per liter). Mechanical dewatering requires less energy, but can typically only get dry matter content up to about 30-35%.

Using the Bio-TTU for drying have several benefits:

• Produces a product with up to 100% DM

• High capacity: Up to 3MT/hr with 40% DM input

• Can utilize waste heat or recycled process heat to power unit which greatly reduces electricity demand and thus also CO2 emissions.

• Effective for feedstock with lower dry matter content (15-20%)

• Effective for feedstock with variable energy value, DM-content, composition, shape, size, and viscosity

 The Bio-TTU can be configured in a number of ways depending on type and quantity of substance, available waste heat and available waste heat receivers. Here are some examples:

Our drying unit will be available for purchase in the last quarter of 2022. For further inquiries, do not hesitate to contact us.

Pyrolysis Application

The market for pyrolysis applications is growing and the benefits are clear: carbon storage, clean energy production, and useful byproducts. However, the main barrier for greater adoption seems to be that no one has yet to come up with a solution that can keep treatment costs low at medium sized volumes (5-20 000 MT annually).

This changes with the Bio-TTU, which have several benefits over competing Pyrolysis solutions:

• High capacity: 2,5MT/hr with 40% DM input

• Utilizes syngas and tars to power unit which greatly reduces electricity demand and thus also CO2 emissions

• Effective for feedstock with lower dry matter content (15-20%)

• Effective for feedstock with variable energy value, DM-content, composition, shape, size, and viscosity

The unit can also be configured to run on 100% electricity if this is desired. For further inquiries, do not hesitate to contact us.
