1 Rapid Thermophilic Digestion Technology Biomax Technologies Pte Ltd Mr Sim Eng Tong, CEO Block 4 Kaki Bukit Avenue 1, #05-07/08, Singapore Phone: Fax: Website: Technology name Rapid Thermophilic Digestion Technology (RTDT) Technology description Rapid Thermophilic Digestion Technology (RTDT) is a patented system invented after 5 years of research by Biomax Technologies Research & Development team. RTDT consists of BM1 and Rapid Thermophilic Digestor (RTD). Together, they act to digest all types of manure into topquality organic, pathogen-free fertilizer in just 24 hours. 1. BM1 BM1 is a natural mixture of thermophilic microbes and enzymes. BM1 is activated only at high temperature; its optimum working temperature is in the thermophilic phase (70-80 C). At thermophilic phase, BM1 greatly speeds up the digestion process of manure. They break up long chains of carbohydrates, cellulose, proteins, fats and lignin into short chains molecules Figure 1. Pouring of BM1 into RTD before the start of the 24-hour digestion process

2 2. Rapid Thermophilic Digestor (RTD) Rapid thermophilic digestor (RTD) is specially designed for the use of BM1. It provides optimum temperature, mechanical mixing, and air flow for BM1 to function. 3. The RTD Process Manure (organic waste) is loaded into the RTD, together with BM1. Then, the digestor is set to run automatically for the next 24 hours. During the 24-hour process, the RTD provides the mixing and aerobic condition; temperature inside is maintained at C. After 24 hours, the complex organic matter in manure is digested into simple organic matter which becomes good quality organic fertilizers (Figure 2). Figure 2.

Benefits of RTDT Resolves all manure problems in 24 hours Converts manure into product high in quality and value Greatly reduces nutrients leaching Greatly reduces carbon emissions Small area required Clean, safe and easy to maintain

3 Documentation of environmental effect 1. Emission reports of RTDT a) CO 2 Table 1. Amount of CO 2 Emission during 24-hour of RTDT process b) Gas pollutants Pollutant Overall Concentration Recorded in 24 hours (mg/nm 3 ) Singapore Environmental Standards for Air Impurities Concentration (mg/nm 3 ) Nitrogen Dioxide < Hydrogen Sulfide < Table 2. Amount of gas pollutants recorded during 24-hour of RTDT process c) Greenhouse gases Greenhouse gases are produced due to anaerobic condition. In RTDT process, constant air flow is supplied into the digestor by air blower inlet. At the same time, the mixer provides 24-hour homogeneous mixing to the raw material in the digestor so there is no build up of anaerobic condition. Hence, there is no greenhouse gases produced from the RTDT process. d) Emission from RTDT end product Sample Ammonia detected (ppm) Fresh chicken manure with wood chips 500 Before going through RTDT Fresh chicken manure with wood chips 10 After going through RTDT for 24 hours Table 3. Amount of ammonia detected on raw material before and after RTDT process

4 e) Summary The emission of various gaseous pollutants during the RTDT process is low. There is substantial drop of ammonia emission from the end product of RTDT compared to raw material which highlights the stability of end product. Finally, there is no greenhouse gas because no anaerobic condition is involved. 2. Effects of RTDT fertilizer on heavy metal leaching in soil Heavy Metal Detected concentration (mg/l) Allowable concentration (mg/l)* Arsenic (As) Barium (Ba) Cadmium (Cd) < Chromium (Cr) Copper (Cu) Cyanide (CN - ) Fluoride (F - ) < Iron (Fe) Lead (Pb) < Manganese (Mn) Mercury (Hg) < Selenium (Se) < Silver (Ag) < Zinc (Zn) Nickel (Ni) < Phenolic Compounds < *Accordance to U.S Code of Federal Regulations (CFR), Title 40, Chapter 1, Part 261 Identification & listing of Hazardous Waste Table 4. Leaching analysis on soil sample applied with RTDT end product Heavy metal leaching is due to the high mobility of heavy metal ions, which depends on the binding ability of soil. Upon applying the RTDT fertilizer into the soil, the organic matter forms soil sorption complex with other soil particles which immobilize heavy metal ions. This process increases the CEC of soil. 1,2 1 Source: Adsorption and migration of heavy metals in soil, Polish Journal of Environmental Studies vol. 10, No. 1 (2001) 1-10 (A. Dube, R.Zbytniewski T.
