Waste Conversion

Müllverstromung & Ressourcenrückgewinnung

NOTE: The term “Waste Conversion” can also include Municipal Landfill Processing, Organic Waste Composting, Waste to Energy (WtE), Waste Management and other terminologies associated with Biogas, Composting, Gasification, Pyrolysis, Plasma Gasification, etc. Such technologies provide the following solutions:

  • Eliminate the need for incineration facilities and Pit Practices;

  • Environmentally sound management of hazardous waste materials;

  • Reduce  storage and transportation costs;

  • Process and thus reduce the currently deposited waste in local landfills;

  • Eliminate leaching problems and the discharge of Methane into the atmosphere.      

At Clean Nature Solutions (CNS), our motto is “Getting it right the first time.” Unlike many in this industry, we understand the importance of challenging the accepted wisdom and encouraging others to do the same. By investing in a robust in-house research and development program, CNS ensures that our products measure up to the latest technological advancements. Our competence combined with customer relationships are key strengths in developing customized systems for many applications.

While profit is an important aspect of the equation for any successful company, it’s not our prime focus. Rather, we have found that a philosophy that places focus upon the needs of our customers from their point of view balanced with proper fulfillment of the regulatory mandates are the first factors to the equation of getting it right the first time. Thorough understanding of each application and the multiple variables involved [on a project to project basis] is the other factor to our equation that results in customer satisfaction and return business every time.

We simply offer our customers the best possible solutions for their projects. Whether off-the-shelf products or customized solutions – our success depends entirely on the satisfaction of our customers.

In general, our products are designed for use under the most demanding conditions. We therefore use only top-quality raw materials from well-established, reputable suppliers. In our production processes, we rely on the expertise and dedication to quality of our team. To achieve our objectives, we offer further training opportunities to our team and a working environment that encourages commitment and diligence.  

For our Waste Conversion Systems & Technologies, CNS has developed a unique, modular-based system thus encompassing a wide spectrum of options and solutions for our customers that are second to none. A modular system allows customers the flexibility of adding or removing features to their system to cover on-demand requirements (i.e. recycling, shredding and/or sorting equipment; flue gas recovery systems, etc.).  Additional features that separate CNS products from others begin with HQ raw materials.  We always start by using only High Quality raw materials in our innovative designs as the backbone to our equipment coupled with proprietary, State-of-the-Art electronics and laser-guided robotics (if applicable) that maximize efficiency and output while minimizing energy loss and human interaction and/or demands…features not found in most other systems currently on the market.

Let CNS help identify the full potential of your project and allow you the freedom to improve your system as needed to meet demand and as budgets allows over time.  We are committed to assisting you every step of the way for the duration of your project. Working closely as a team with our Engineers, Project Managers and Technicians, our customers will feel confident knowing that we stand with them through every step to help identify their needs, specifications and thus a Best Possible Solution for the long term. The first step to this process is completion of our questionnaire (link provided below) which helps identify your initial needs and requirements. Our Marketing & Sales team will assist you through the next steps.

CNS can offer customers a number of small to mid-scale Waste Conversion options (new and emerging technologies) that are able to an assortment of energies and/or materials from waste without direct combustion. Based upon a customer’s specific needs and desired outputs (determined by the Questionnaire), CNS can help design a customized system able to convert a wide range of inputs or “feedstocks” into a number of outputs (biofuels, electricity, gases, recyclables, value-added products, etc.). CNS also offers specialized consulting services to help customers determine a “Best Corse of Action” based upon a fact finding survey included in the consultation package. Here are some (but not all) of the possible Waste Conversion Systems we can offer (each can be considered as individual, stand-alone systems or as modular—added as needed based upon desired configurations):

Thermal-based technologies:

  • Gasification—uses a wide-range of organic and inorganic feedstock to produce combustible gas, hydrogen, synthetic fuels). This process converts organic or carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide via reaction of material at high temperatures (>700 °C), without combustion and controlled amounts of oxygen and/or steam resulting in a synthesis mix of gases called syngas [itself a fuel], usually requiring further processing but considered a source of renewable energy if final product obtained from the processing of biomass. Gasification systems are scalable (available in mobile to large-scale processing plants). Modular units and various options are available through CNS assistance.

  • Pyrolysis—Uses a wide-range of organic feedstock in the absence of oxygen to produce gas, liquid products (bio oil, fuel) and leaves a solid residue material high in carbon content and commonly referred to as char. The process is used heavily in the chemical industry to produce charcoal, activated carbon, methanol and other wood-based materials. Also used in the coal industry to convert coal into coke and to convert biomass (agricultural applications) into biochar and syngas. Pyrolysis also offers conversion of hazardous materials (medical waste) into safely disposable products or further processing resulting in lighter weight fuels such as diesel and gasoline. Electricity is another possible output.  Pyrolysis systems are scalable (available in mobile to large-scale processing plants). Modular units and various options are available through CNS assistance.

  • Fast Pyrolysis—as described above but designed differently as a means to use discarded tires primarily as its feedstock. Also scalable from mobile to stationary, large-scale systems.

  • Plasma arc gasification or plasma gasification process (PGP)—uses the widest-range of feedstock (usually unseparated municipal waste) to produce a rich syngas and other gases such as hydrogen and carbon monoxide as a resalable material. Electricity and slag for use in building materials are other common outputs. PGP is highly modular with many configurations including recycling of specific metals. Currently, our PGP systems are utilized for small to mid-scale landfill mining, large city municipalities and also in the processing of hazardous and low-level nuclear waste materials. CNS can offer customers a wide-range of options with PGP including scalability, recovery of precious metals and other recovery options.

Non-thermal technologies:

  • Anaerobic digestion—Used in Agricultural and Waste Water applications, AD is a collection of processes in which microorganisms break down biodegradable materials in the absence of oxygen thus providing rich biogases such as methane which can be sold as a fuel or further processed into a source of alternative energy. This technology is scalable and very affordable.

  • Mechanical Biological Treatment (MBT)—Is a biological treatment system commonly referred to as “composting” or a waste processing facility that uses specific feedstocks (mixed household wastes, organic wastes from food production and other commercial and industrial wastes that are subject to the compost cycle. Output or products can be rich soil amendments for crop production, various fuels derived from methane gases and electricity. Two more primary forms of MBT include:

    • MBT + Anaerobic digestion

    • MBT to Refuse derived fuel

NOTE: The use of CNS process technologies to secure relatively homogenous output materials of specified composition will enable: (1) the concentration of contaminants for onward disposal or treatment and (2) production of recyclate to a desired quality, prolonging their utility.
MBT plants designed by CNS engineering are designed for effective, high quality materials flow management. We use integrated, modular mechanical processing and biological reactors to convert and separate residual waste into output streams of suitable quality. Typical outputs include biostabilized material, dry recyclate matter and waste-derived fuels (WDFs).
