The Prowst Process
Regenerating Natural Resources
The PROWST® Process
Circular economy in practice

A continuously industrial feeding system a 24/7 process.

The key factor for thermolysis is to provide the processor with feed stock with zero-oxygen in order to create an exothermic reaction, a chemical or physical reaction that releases heat. Due to the construction of our feeder, we are continuously able to feed the processor feed stock without letting the oxygen into our processor.


  • No batch processing
  • Zero oxygen provide a continuous process

The Feeding system

The feeder construction is unique and superior other technologies due to
allowing the production to be run 24/7.

  • Allowing the production to be run 24/7
  • Fed with a variation of problematic organic feed stock, one at a time.
  • Handle feed stock quality from very fine to rough cut


Unique heating system

An exothermic reaction is a chemical or physical reaction that releases heat. It gives net energy to its surroundings. That is, the energy needed to initiate the reaction is less than the energy that is subsequently released. Depending on materials the exact constant temperature in the process is crucial. In order to achieve the most efficient constant temperature for the exothermic reaction, the PROWST has a unique technique for controlling and regulating the temperature during the process.

  • Controlled constant temperatur


Regenerating natural materials

The output from the PROWST® process unit, oil, gas, carbon black and some ash is gathered and stored in different containers. The oil and gas can be used to produce electricity via a power plant. The excess heat is taken care of via different heat exchanges and that energy can be converted to electricity or/and cooling for buildings such as hospitals or universities. All is depending to the agreement considering the plant.

  • Biogas
  • Bio-oil
  • Carbon Black
  • Phosporus
  • Metals

Some see waste, we see resources
Beneficiaries of the PROWST process
Our PROWST® process is an economical power generation technology that have highly diverse fuel functionality, making it adaptable for a number of industry sectors and energy consumers.

circular economy
Waste and resource use are minimized, and when a product reaches the end of its life, it is used again to create further value.

In a circular economy, the value of products and materials is maintained for as long as possible. The EU Action Plan for the Circular Economy outlines a set of both general and material-specific actions. While some obstacles to a circular economy are generic, different sectors and materials face specific challenges due to the particularities of the value chain. The Directorate-General for Internal Market, Industry, Entrepreneurship and SMEs cooperates with other Commission departments on the following actions.

Product design • Production process • Consumption • From waste to resources (secondary raw materials) • Innovation, investment and other cross-cutting issues

A number of materials and sectors face specific challenges in the context of the circular economy. Waste Reform is active in the ”From Waste to Resources” sector.

The transition to more circular plastics and plastics value chain is an opportunity for the EU society and economy.
Food Value Chain
Manure & Fertilisers
Manure that cannot be transformed into fertilisers are currently being stockpiled or burnt in an unsustainable fashion.
Critical Raw Materials
The very low rate of recycling of most of these materials means that significant economic opportunities are lost.
Construction & Demolition
A tonne of construction and demolition waste is produced per person per year – i.e. 500 million tonnes in the whole EU every year. Valuable materials are seldom identified and recovered.
Biomass & Biobased products

sustainable development goals
The 2030 Agenda for Sustainable Development, adopted by all United Nations Member States in 2015, provides a shared blueprint for peace and prosperity for people and the planet, now and into the future. At its heart are the 17 Sustainable Development Goals (SDGs), which are an urgent call for action by all countries – developed and developing – in a global partnership. They recognize that ending poverty and other deprivations must go hand-in-hand with strategies that improve health and education, reduce inequality, and spur economic growth – all while tackling climate change and working to preserve our oceans and forests.
