Recuperación de energía y fosfatos de biomasa/lodos mediante un método redox innovador


Oferta Tecnológica
Una empresa alemana ofrece una tecnología redox patentada para recuperar fosfatos de biomasa o lodos y generar energía neutra en CO2 al mismo tiempo. El fosfato puede emplearse como fertilizante. El proceso único de extracción de fosfato permite producir energía renovable, como energía térmica y eléctrica, y volcarse a la red nacional. La tecnología reduce los metales pesados considerablemente y elimina sustancias orgánicas peligrosas. Gracias a su diseño modular, la tecnología es ampliable. Se buscan investigadores y socios industriales y del sector público con el fin de establecer acuerdos de licencia, investigación o comercialización con asistencia técnica.


Energy and phosphate recovery from biomass/sewage sludge with an innovative redox method
A German company offers a patented redox technology that recovers phosphates from biomass or sewage sludge while at the same time generating CO2 neutral energy. The phosphate can be used as valuable fertilizer. The technology reduces heavy metals significantly and eliminates harmful organic substances. It is expandable thanks to modular design. Partners from research, industry or public sector are sought for licensing, research or commercial agreements with technical assistance.
A German company offers a technology to extract phosphates from biomass/sewage sludge by using an innovative, worldwide unique and patented method. The unique phosphate extraction process allows to excite renewable power as thermal energy or electricity that can be fed into the national grid.

Phosphate is an essential element for all creatures and a driving force for the metabolism of all living cells. Especially for plant nutrition in form of fertilizers, phosphate plays a significant role. Moreover phosphate is a substantial component for bone substance and also comprised in sewage sludge.

According to notable international research institutes best estimates, the natural reserves of phosphate will be exhausted within 100 to 300 years. Hence, the recycling of phosphate will be the one and only way to secure the enduring provision of this essential element. Soluble biomass phosphates bound in bones, bone meal, carcass meal and waste water sludge represent in many areas of the world a significant phosphate resource.

The German company extracts phosphates from biomass with a special redox process: Pyrolysis (reductive) combined with subsequent thermal post-combustion (oxidative) converts phosphate-containing biomasses into highly concentrated, extremely pure mineral phosphates.

The redox-method of the German company is an innovative and worldwide unique method During the redox process a complete segmentation of the biomass into thermal energy and a mineral residue (the recycled raw phosphate) takes place. The minerals residue is composed of calcium carbonates and oxides as well as highly concentrated and chemically pure calcium phosphates. As a side product, the redox process also generates large amounts of CO2-neutral energy. The utilisation of CO2- neutral energy can vary from electricity generation over deployment for drying to drinking water purification.

Important characteristics of this redox-process:
- Production/recycling of the finite resource phosphate and the generation of renewable and CO2 -neutral energy
- Highly concentrated alkaline earth phosphate
- Low-contaminated phosphate (cadmium und uranium)
- Significant reduction of heavy metals
- Complete transformation of carbon into energy gases and thermal energy utilisation with combined heat and power

The company is open to various types of cooperation, such as licensing by country or commercial agreements with technical assistance as well as research cooperation with regard to nurtients in fertilizer.
Partners could be active in meat production, fertilizers, public sector, engineering, agricultural research and others
Advantages and Innovations:
The unique competitive advantage of this technology compared to other competing phosphate-recycling is the patented innovative thermic recycling method. Today´s common way of phosphate recycling via extraction out of sewage sludge has one crucial issue: The elimination of chemical heavy metal compounds, drug residues and other organic harmful substances requires a comprehensive extraction process which render the processes uneconomical in the long run. These constraints can be overcome with the new innovative technology developed and incorporated by the German company. Thus, the German company will have a significant competitive advantage in terms of technology and product quality.
