Welcome to Sinowatek!

Turning wet waste into value

We transform producers’ value chains into more sustainable and profitable cycles by unlocking the circular economy of their product-specific waste.

What is a circular economy?

The classic definition of the concepts of sustainability and sustainable development lies in the Brundtland Report of the United Nations,1987, which defines sustainable development as development which meets the needs of the present without compromising the ability of future generations to meet their own needs.  Based on this definition, current economic growth is not sustainable, because it follows a linear production model with finite resources and a limited capacity to absorb waste.  The ability of future generations to meet their needs on the planet is therefore severely limited by the depletion of natural resources on the one hand and the excessive accumulation of waste on the other.

The circular economy provides a potential solution to this predicament.  It is a technology-focused model that generates economic growth while reducing pressure on the environment.  It is premised on three principles, namely the elimination of waste and pollution, the circulation of products and materials and the regeneration of the environment.

Sinowatek’s process of creating a value cycle


The first step in the valorization of wet waste is the dewatering of the viscous mixture, seperating it into liquid and solid fractions. We selected the appropriate high-quality, innovative, eco-friendly technology to dewater the wet waste. Next, we treat and transform these waste products.

Grey Slurry sludge


The solid fraction, still in viscous form, is valorized by drying it into a powder with the progressive, energy-efficient pulse combustion drying (PCD) technology.

The water-bourne filtrate is treated with cutting-edge, environmentally-friendly SulafectTM disinfectant.

Commercial output products

A circular economy is created by linking transformed waste products back into the value cycle – profiting businesses while protecting the environment.

Case studies


Beer brewing process waste management & disinfection

Breweries around the world are obligated to recover, recycle, reuse, or reduce process waste.



Sustainable water & waste management at livestock farms

There is a tremendous opportunity for farmers to exploit the circular economy potential of animal manure sludge.



Abattoir blood waste processing

Waste from abattoirs has the potential for recycling raw materials, as well as for conversion into useful by-products.



Paper and pulp sludge dewatering

Our dewatering technology is used to treat the sludge so that it can be used to create new value-added products.



Municipal wastewater sludge dewatering

It is important to unlock and maximise the potential of sewage sludge as a value-added product for use in various sectors.



Mining sludge dewatering

The circular economy model for the mining industry has significant potential to solve the challenges of shortage of mineral resources.



Drying of chemical compounds in solution or suspension

Drying is one of the main processes to produce high-purity powders from chemical compounds which are in solution or suspension.



Food & food waste preservation with pulse combustion drying

By using the progressive PCD technology to preserve food and food waste, businesses can create new value-added products and close the circular economy loop.



Disinfection of process water & drinking water systems

SulafectTM is a disinfectant where the concentrate is produced exclusively from drinking water, electricity, and high purity salt and therefore it is safe to handle, easy to store and have no harmful by-products.




The biogas process also generates a process-specific by-product known as digestate which requires processing.
