6 1. General Project Activity and Monitoring Information 1.1. Title and Registration Number of the Project Activity, Registration Number Short Description of the Project Activity: is a project designed to explore the landfill gas produced in Bandeirantes landfill, one of the biggest landfills in Brazil. This landfill is located in the metropolitan region of São Paulo, Brazil s biggest city and financial center of the country. With an estimated population of around 10 million citizens in 000, São Paulo generates nearly tons of waste daily. Bandeirantes Landfill Gas to Energy Project (BLFGE) s goal is to explore the gas produced in Bandeirantes landfill, using it to generate electricity Real Project Implementation Bandeirantes landfill is divided into 5 cells, named AS-1, AS-, AS-3, AS-4 and AS-5. The former 3 are the oldest ones, which operated from 1978 until Bandeirantes Landfill Gas to Energy Project (BLFGE) has since its start been extracting gas from the newest cells, where there is still waste being disposed. Two main units can be detached: the degassing stations and the power plant. Figure 1.1. Bandeirantes Landfill Cells The degassing stations are responsible for extracting the landfill gas from the landfill and transport it to the gas engines in the power plant. During the transportation, the gas goes through a treatment to allow its use as fuel for energy generation. Other functions of the Page 1

degassing stations are: drying landfill gas by gas coolers; and measuring and analyzing the quantity and quality of the landfill gas for safety, process and operating purposes. B A B A Figure 1.

This is drained to condensate shafts, placed nearby the gas pipes. Once in the degassing stations, the landfill gas has to be cooled again to remove moisture.

After this step, the gas is heated again through a second heat exchanger, or economizer, to a temperature of around 5ºC, far enough from the dew point of 4 o C to avoid further condensation.

7 degassing stations are: drying landfill gas by gas coolers; and measuring and analyzing the quantity and quality of the landfill gas for safety, process and operating purposes. B A B A Figure 1.. Degassing Station (A) and Power Plant (B) The landfill gas cools down when transported from the landfill, resulting in a condensate. This is drained to condensate shafts, placed nearby the gas pipes. Once in the degassing stations, the landfill gas has to be cooled again to remove moisture. This is a very important step in the gas treatment process, since the condensate, which contains silicium components, could block the gas pipes and also damage the gas engines, due to the silicium. After this step, the gas is heated again through a second heat exchanger, or economizer, to a temperature of around 5ºC, far enough from the dew point of 4 o C to avoid further condensation. Considering demoisturing is fundamental for the energy generation, as per the reasons mentioned in the previous paragraph, a demister has been installed for extra-safety reasons. The demister is a stainless steel high density filter which separates liquid particles (small amounts of condensate) from the landfill gas. This liquid is to be drained off to a condensate shaft as well. The blowers are used for transportation of the landfill gas from the landfill to the gas engines, under correct suction and pre-pressure. Capacity and pressure are adjusted through frequency controlled electromotors. Moreover, the blowers are equipped with all the necessary safety equipment, including a noise reducing housing. Figure 1.3. Compressors (blue) and dryers (metal) Page

On the pressure side of the degassing station, all kinds of gas analyzing and gas measuring instruments are present.

After the described treatment, analyzing and measurement, the landfill gas is transported as a fuel to the gas engines.

8 On the pressure side of the degassing station, all kinds of gas analyzing and gas measuring instruments are present. These instruments are very important for safety, process and operating purposes. After the described treatment, analyzing and measurement, the landfill gas is transported as a fuel to the gas engines. These drive electrical generators in order to generate electrical power. An occasional surplus of the landfill gas can be burned off by the flares. Figure 1.4. Turbine Flow-meter Figure 1.5. Generators used to produce electricity Figure 1.6. Flare used to destroy the surplus gas collected The whole process is controlled by an electrical control system. This control system is provided with a PLC (Programmable Logical Controller). All the measured process signals are processed by the PLC to output signals for the gas-coolers, blowers, flares and gas-engines. Also the system counts on a SCADA system (process visualization on a personal computer). With this system it is possible to control and monitor the installation at a distance, including through the internet. Page 3

9 Figure 1.7. PLC Controlling System panel For electricity generation, a total of 4 Caterpillar engines, nominal capacity of 95 kw, model 3516 A were installed. They will burn the gas and generate energy, which is to be sent to Eletropaulo s the electric distributor supplying São Paulo metropolitan region grid. This electricity will in fact not be commercialized directly; it will supply Unibanco s branches over São Paulo state Changes against the PDD The changes made against the presented in the registered PDD are: Installation of 4 new flow-meters to measure the gas flow to the power house (please refer to Annex II); periodical monitoring of methane content in the exhaust flare gas, made by a specialized company on gas analysis; changes in the gas station s lay-out (please refer to Annex III). This change was necessary in order to adapt the gas station to treat an increase of landfill gas collected (average Nm 3 /h) Monitoring Period The monitoring period is from 01/01/007 to 30/06/ Methodology applied to the project activity Baseline methodology The baseline applied to this project activity is ACM0001 version : Consolidated baseline methodology for landfill gas project activities Monitoring methodology The monitoring methodology applied to this project activity is ACM0001 version : Consolidated monitoring methodology for landfill gas project activities.

10 1.7. Changes since last verification The major changes from the last verification are the installation of 4 new flow-meters to measure the gas flow to the power house (as mentioned in 1.4) and a change in the gas station s lay-out (as mentioned in 1.4) Resolution of CARs and FARs from the previous Verifications The following table presents the issues raised during the last Verificat and their resolutions: TYPE OF ISSUE RAISED RESOLUTION Forward Action Request #4 (Verification Report N o Version, amended according to EB meetings 6, 7 and 8, from 05/0/007): Biogás is already developing the procedures to implement such Program. The on-site audit is scheduled to October/007. Standard procedures for CDM activities within Bandeirantes LFGTE project are necessary. They could be part of the upcoming ISO 9001:000 implementation. A delay of ISO implementation could lead to the same errors in the next verification activity. Procedures should include: - Document Control - Data safety measures (backup and sabotage) - Monitoring Report Preparation (frequency, responsibilities, crosschecking measures, legal binding signature in monitoring reports,etc.) - Data Spreadsheets - Error management (including software errors, material errors, etc.) Corrective Action Request #1 (Verification Report Version 1, from 30/03/007): Project Proponent should explain how this data was recovered from the logger until they have a procedure to reduce errors in this operation. This means an internal audit of data collected. Forward Action Request #1 (Verification Report Version 1, from 30/03/007): The company responsible for the system automation identified that the problem was the competition between the PLC and the anti-virus and suggested the installation of an exclusive computer to the PLC, without internet access. Also, the internal procedure was strengthed. As requested, the data from the new flowmeters are available on items.1.1 and.1. of the Monitoring Report. Given that the technical arguments for calculation of LFG to Energy flow by the difference between LFG to flare flow and total LFG flow are reasonable, also taking into Page 5

11 account uncertainties of measurements, results could be considered acceptable for this opportunity again. For the next verification the project proponent should include the new measures (manually and by PLC), considering the data obtained by the difference between LFG to Flare flow and total LFG flow, mentioning in the 4th Monitoring Report, the date in which the 4 new Flow meters come in operation, thus reflecting in the calculations. Raw data should be shown. This will be part of the next verification activity (4th). Forward Action Request (Verification Report Version 1, from 30/03/007): In the next verification, Project Proponent should evidence the certificates from Pressure, Temperature and Logger installation related to the new equipment (flow meters to the Powerhouse). All documents were presented to the Verification Team, during the on-site audit Person(s) responsible for the preparation and submission of the monitoring report This monitoring report was developed and reviewed by: Eduardo Cardoso Filho ARCADIS Tetraplan S/A Avenida Nove de Julho, 5966 Térreo São Paulo SP Brazil CEP: Phone/Fax: + 55 (11) eduardo@tetrapan.com.br Antônio Carlos Delbin Biogás Energia Ambiental Rua Mogeiro, 1510 São Paulo SP Brazil CEP: Phone/Fax: + 55 (11) delbin@biogas-ambiental.com.br Page 6

A new collecting line was installed and the gas collected is measured by the flow-meter FIR700 and is sent exclusively to the flare F00. The pictures below present the new lay-out. The mini blower previously connected to the main pipeline will be connected directly to the flaring system the existing pipeline will be removed and a new pipeline and the new flow-meter FIR700 will be installed. The valve between the flares F100 and F00 will remain closed. Both flares F100 and F00 will be constantly operational. This valve will automatically open if necessary, according with an internal procedure PO-O16 (for example, when maintenance in the mini-blower is required). The readings from the new flow-meter will be made automatically and the monitoring will be made via the PLC system. Page F
