4 Prospective partners for GRENOL in the Philippines We are GRENOL, and we are searching for companies/ investors as our prospective customers and/or operators of industrial-sized HTC facilities Prospective Partners for HTC-Projects in the Philippines: Group 1 Companies or Organizations with large quantities of organic waste Industrial companies with biomass waste: e.g. food producers, producers of fruit juice/drinks, breweries, wine makers, large restaurants & food chains Local governments and communities for urban waste management with large quantities of organic waste Farms with organic waste from food production & green waste Large touristic resorts, hotels etc. having abundant organic waste Group 2 Companies or organizations and Climate Change Advocates interested in establishing a green decentralized energy production facility (electricity, heat/cold) from organic waste Large touristic resorts, hotels etc./communities. e.g. on remote off grid areas

5 What is HTC? Hydrothermal Carbonization is the conversion of biomass to coal-products and water in a closed system under conditions of heat and pressure. Technical parameters: HTC takes place at a temperature of approx. 220 C and 22 bar pressure HTC is a physico-chemical process, an exothermic process: Heat is produced during the splitting of carbohydrates chains into carbon and water (e.g.: sugar C 6 H C + 6 H 2 O) Carbonization takes place within a very short time (3-12 h) Almost 100 % of the carbon and 2 / 3 of the energy are conserved

13 Required space for the HTC-Reactor & periphery: ~ 1500 m² area is needed for a HTC-plant with a capacity of t biomass/d and t coal/y output

14 Usage 1: Conversion from coal to power & heat dosage and pre-heating of the biomass waste HTC-biomass-reactor biomass-waste combined heat & power unit coal-water separation, control system and heatmanagement HTC-biomass-improvement CO 2 -neutral coal power & heat unit generator HTCwater HTC-fertilizer

15 Usage 2: Conversion from sewage sludges Canalisation Grit chamber Preliminary sedimentation Activated sludge Clarifier rack Increase of the methane production with HTC process water Sludge - Thermal disposal - Output for agricultural use Water bodies Sludge Debris & sand HTC-Reactor 230 C & 25bar HTC-Water Digestion tower Biocoal Hormone & Antibiotics free Centrifuge Humus

17 Testing of soil auxiliary material with products from the hydrothermal carbonization process Experiments for the development of soil auxiliary with humus-like materials from Hydrothermal carbonization (HTC) were conducted sucessfully in recent years. The development to a market level goes on in cooperation with local instutions specialized in agricultural research.

18 Benefits of HTC-Technology 1. Benefits concerning Biomass: Any biomass, wet or dry, and any mixture can be processed. Ecological resources are preserved (crude oil, gas, coal). No competition with the food industry!! Farmlands are preserved. 2. Benefits concerning waste management: HTC technology closes the waste management cycle and offers a climate and environmentally friendly way of processing all forms of organic waste from rural and municipal areas. Decentralized solution for waste management Helps prevent spread of diseases from municipal waste HTC is a very space saving technology

19 Benefits of HTC-Technology 3. Benefits of the HTC process: Contrary to combustion, fermentation or biogas, GRENOL HTC- Technology is a physico-chemical, not a biological process. HTC is more carbon efficient than any conventional procedure, 100 % of carbon, 2 / 3 of energy are preserved. No discharge of CO 2 or Methane. Hygienic Advantage: Pathogens, hormones, antibiotics, pesticides and other harmful compounds are destroyed. 4. Benefits of the HTC reactor: HTC takes place within a closed system (Machinery). Compact units enable decentralized installations.

20 Benefits of HTC-Technology 4. Benefits of the HTC reactor: Well established components Easy mechanical handling 5. Benefits concerning Output of HTC process: Wide range of applications of humus and coal: humus and soil optimizer, bio coal pellets (storable energy), chemical base products, absorber coal, isolation etc. HTC Water contains valuable components; ions, which can be used for the production of additional biomass in large quantities at a rapid rate. HTC Water and humus can be useful for cultivating desert regions

21 Conclusion GRENOL HTC-Technology offers a new alternative procedure to process organic waste in an environmentally friendly way and closes the cycle of waste management. HTC technology is a convenient, efficient and inexpensive way for the densification of organic waste: HTC coal is ideal for storage and transportation. The GRENOL HTC Reactor is the perfect solution for the decentralized production of electrical energy and heat/cold.
