Dehalogenation

Current Solutions

Current solutions are based on:

i)  engineering of new adsorbents that require regeneration and /or;

ii) subsequent incineration at 1100°C generating nasty fumes.

SweetGen Solution

We turn the toxic and carcinogenic contaminants into their hydrocarbon counterparts which renders the effluent compatible with existing biological reactors.

Get in touch

Plug and play modular reactor
Continuous and selective process
Low CAPEX and OPEX (room temperature and ambient pressure)

How it works

The contaminated water is pumped into the reactor and in contact with the catalyst the C-F or C-Cl bonds are replaced by C-H ones plus F or Cl anions

Works also for short chain molecules -
unlike adsorption-based solutions

Our application benefits

Purely catalytic, no adsorption or regeneration of the solid is required
Works best for short chain molecules
(unlike adsorption-based solutions)
Reactor compatible with existing facilities

Disinfection & sanitation

Current Solutions

Current sanitising solutions require a high concentration of active species to achieve good disinfection rates. This is particularly relevant in medical grade applications in which fast reactions are mandatory.

Use of peracetic acid enables for fast disinfection. For instance, recent studies suggest that SARS CoV is completely inactivated by peracetic acid, after < 1-minute exposition and with concentrations as low as 0.035%. However, peracetic acid is currently produced in strong acids (H₂SO₄) which hinders applications in which the acid can generate damage to the equipment, medical applications

SweetGen Solution

We generate peracetic acid at room temperature and ambient pressure without any strong acid. Moreover, we can produce new peracids from natural sources.

Our product can be tuned to target applications including hand sanitising, surface cleaning, high level disinfection and sterilisation.

How it works

An aqueous solution containing an inexpensive and even naturally occurring precursor is passed through our catalyst and in contact with oxygen from air is directly transformed into a peracid

Our application benefits

Compatibility with biomedical applications
Transport safety issues removed through decentralised production
Fast and efficient disinfection in seconds

Food & packaging

Current Solutions

Food preservation and oxygen scavenging. Many foods are very sensitive for oxygen, which is responsible for the deterioration of many products either directly or indirectly.

The use of oxygen scavenging packaging materials means that oxygen dissolved in the food, or present initially in the headspace, can potentially be reduced to levels much lower than those achievable by modified atmosphere packaging. In this context, research and developments in the food packaging area have been conducted, aiming to eliminate residual O₂. One of the most attractive subjects is the active packaging concept.

Active packaging includes oxygen and ethylene scavengers, carbon dioxide scavengers and emitters, humidity controllers, flavour emitters or absorbers and films incorporated with antimicrobial and antioxidant agents.

SweetGen Solution

Our catalyst material is highly selective to oxygen and thus can be applied in a suitable formulation within those active packaging concepts.

Get in touch

Our catalyst contributes to extend product lifetime and minimises the use of plastics therefore increasing their recyclability.

How it works

Oxygen diffuses through the packaging. Rather than passing through, with the help of our catalyst it is consumed within the packaging barrier and thus does not come into contact with the food.

Our application benefits

Highly selective to oxygen
Low amount needed
Fast kinetics mean oxygen is quickly consumed

Wastewater treatment

Large amounts of wastewaters that contain a high load of organic contaminants are produced by industries such as food or snack, and beverage industry. These effluent compositions include sugars, alcohols, volatile fatty acids, and other dissolved compounds. For companies in developed countries and indeed many developing countries, stringent regulation forbids the discharge of water with this high organic contamination directly into rivers and seas. Consequently, this wastewater either needs to be cleaned on-site incurring high capital and operational costs or is discharged to the municipal treatment facility at a hefty surcharge.

SweetGen Solution

Unlike biological reactors in which aeration is not efficient, SweetGen’s technology offers an oxygen transfer efficiency of well over 10% (versus less than 4% for membrane bioreactors) and the reactor does not involve sludge formation. Consequently, abundant reaction-available oxygen can be used to efficiently decrease the contamination (measured as chemical oxygen demand) from various waste streams. Unlike the standard catalytic materials utilised for the oxidation of organic molecules which undergo deactivation and poisoning with loss of activity, our IP-protected catalytic materials are unique.

Get in touch

Aeration represents more than 50% of costs in water treatment facility. Our technology will enable 3 times lower cost thanks to improved oxygen transfer efficiency.

How it works

The wastewater which contains organic species is pumped into the reactor. A flow of air at ambient pressure is added simultaneously.

The oxygen in air is activated at the surface of the materials and subsequently attacks the organic species leading to their full oxidation to CO2.

Our application benefits

Compatible with waste waters which are toxic to biological. Reliability robustness compared with biological systems
Low space footprint
50-90% smaller than
comparable biological systems
Up to 95% reduced OPEX compared to advanced oxidation processes which are currently used for toxic chemical wastewaters
