HISTORY OF MCWM
The Clark The Clark Special Economic Zone (CSEZ), located (CSEZ), located some 80 kilometers north of Metro Manila, Philippines is comprised of a 4,400-hectare Main Zone and a 29,213-hectare SubZone. Currently, it is being developed into a model metropolis built around the Diosdado Macapagal International Airport.
Its master plan has provided Clark‘s reconstruction as a residential neighborhood, mixed-use business district, recreational and entertainment center, support and aviationrelated facility, parkway and rail link, industrial estate and the site of a world-class international airport.
The Clark The Clark Development Corporation (CDC), (CDC), a government agency tasked to manage the Zone, solicited proposals from various waste management companies for the handling of the solid waste generated by its locators companies. The bidding was won by a German Consortium composed of Birkhahn Nolte GmbH and Heers & Brockstedt Umwelttechnik GmbH.
The German Consortium later formed the company ―Metro Clark Waste Management Corporation‖ (MCWM) wherein 30% is owned by the Germans and the remaining 70% is owned by various Filipino investors. The contract basically calls for the establishment of an integrated waste management facility, to be operated for twenty-five (25) years, with focus on landfilling for final disposal.
Some highlights of the integrated waste management center are the following:

II. SERVICE OFFERED
Metro Clark Waste Management Corporation provides, promotes and maintains environmentally responsible practices of waste disposal. The object of their service is to benefit their customers, consumers, employees, communities and the environment by doing the business in ways that protect and demonstrate good stewardship of the world‘s natural resources. Also, MCWM continually seek new ways to address the environmental cost and impact of their landfilling activities, products and services.
Development and Construction of a Cell on the Year 2013
MCWM is dedicated to developing sustainable solutions for minimizing the environmental impact of urban development and energy production projects. Our team works both in Europe and Middle East to develop Clean Development Mechanism projects and reduce greenhouse gas emissions and saving energy.

As a landfill, MCWM produces by-products such as leachate and methane gas. For this matter, the business provided a Leachate Treatment Pond to monitor and treat that unwanted by-product so as to avoid any environmental impacts. With regards to the methane gas which could be a source of energy, MCWM, on 2011 installed a methane gas collector. However, upon the company‘s assessments, the amount of gas being collected is not enough to build a power plant.

2. Getting a Gate/Yard Pass
The delivery truck comes in the premise of the facility and obtain a Gate/Yard pass. This is for tracking purposes.
3. Inspection
Contents of the hauler will be inspected to ensure that only the required waste will be disposed in the facility.
4. Initial Weighing
The hauler/waste generator will pass through a weigh bridge. This will determine the initial weight of the truck, that is the weight of the empty truck plus the weight of the waste to be disposed.
5. Waste Disposal
After the type and amount of waste determination, the hauler/truck will then go to the designated land fill area for that specific type of waste to dispose its contents. From this point, heavy equipment machinery will facilitate to the proper land filling. That is, the wastes will be compressed until a cell is completed. Compression of the wastes is in a ladderized manner called benching to provide a sturdier structure. After compression, the compacted waste will be flattened and then will be covered with clay.
12 | P a g e
The landfill is well designed in such a way that no leachate will harm or
contaminate the groundwater. This is by using multilayered protective materials which prevent leachate form passing through the soil thus avoiding the contamination of the water reserves underground and a HDPE tube which sends the leachate to the Leachate Treatment Plant. A more detailed description of the landfill can be read in the quality control part of the text.

6. Washing
Washing of the truck will come next after the disposal. The wash water will be directed into a pond where it will be treated. This step of the whole disposal process assures the safety of the community surrounding the facility.
7. Final Truck Weighing
Another truck weighing will be employed after the washing step. This would monitor the amount of waste being disposed (it can be computed by subtracting the weight of the truck after washing to the initial weight of the truck) and thus, would allow the determination of the disposal fee. The disposal fee is listed in the table.

QUALITY CONTROL PROCEDURES
In order to provide the best quality service the y can give, MCWM has the following to control their process. These are: 1. Facilities 2. Strict Requirements for Disposal 3. Sanitary Landfill that Exceeds the Standards stipulated by RA 9003
Fac il it ies Some highlights in MCWM‘s integrated waste management center that could help maintain the quality of their service are:
Entrance station with weigh bridge
Before entering the premise, waste generators must first obtain a gate pass. This would allow MCWM to record and track all that are being input in the facility.
Leachate storage and treatment ponds
Before disposing waste water in the environment, all are first treated. To ensure that the effluent comply with the stand ard, tests are done quarterly by the government. Some of the parameters being tested are the Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and color.
Environmental buffer zones / re-greening zones
Their environmental buffer zone is designed to monitor the safety of the operation. This serves as an indicator whether their effluents, specially the air, comply with the standards.
Administrative buildings
This would cater the needs for management functions.
Materials recovery facility (MRF)
The MRF would allow reusable materials to be recovered, thus decreasing the amount of waste being disposed in the landfill.
15 | P a g e
Workshop
Workshops would help employees to understand more the rationale of the operations being done. Understanding every aspect of the operation would result to a more quality service.
Runoff water collection system
Retention basins
Recycling and waste treatment facilities
Strict Requirements for Disposal
Standard requirement for sludge and ashes which are out of industrial processing is the TCLP analysis (US EPD Standard); it has to be within the described TCLP limits and so far as necessary DENR confirmation as ―non-hazardous‖. Asbestos has to be certified as NON-FRIABLE.
The waste generator has to provide MCWM with test results before finalization of the disposal contract.
MCWM will conduct ―backup‖ analytics on site for each delivered charge. If a charge fails the limits or shows total different consistency of the delivered materials, MCWM will have the right to reject the charge.
Furthermore, MCWM has the right to require additional tests, if necessary, to insure that no hazardous materials are disposed in their facility.
MCWM has the right to reject charges due to operational reasons.
MCWM will provide the Generator / Hauler with a ― Certificate of Final Disposal ‖ / ―Letter of Destruction ‖ in accordance to RA 9003.

Sanitary Landfill that Exceeds the Standards stipulated by RA 9003 The SANITARY LANDFILL (SLF) in Sub Zone D, Clark Special Economic Zone, Sitio Kalangitan, is build based on international accepted standards, which exceed the standards as stipulated in RA 9003 substantially.
The protection layer which insures that no liquids (leachate) from the landfill could harm the soil or the groundwater is basically based on a redundant liner system out of natural and artificial materials with extreme low permeability. Further the local geology with very dense clay material protect the groundwater, which can be found in the area of the landfill about 60m below the surface.
Baby Landfill Showing the Parts of the Engineered Design of the Facility
T he
technical protection layers are built out of a 0.75 m thick clay liner (implemented highly compacted) and a 2.5 mm HDPE (high density polyethylene) plastic liner. An additional layer of geotextile is placed to protect the HDPE from sharp wastes.
17 | P a g e
MCWM opted to use German technology manufacturing and installation of the HDPE liners.
The drainage system for the leachate is built out of a HDPE pipe system (which can sustain more than 80m waste load) and a real gravel filter, which would insure that all incoming leachate could be forwarded to the Leachate Treatment Plant. The pipe is spiral in shape so as to ensure that the said pipe will not be destroyed easily.
The temporary Leachate Treatment Plant for the phases 1 + 2 is built as a ration ponds with the additional utilization of specialized enzymes for the complete cleaning of the water. Further filtration through a ‗reed bed‘ is planned.

IV. ENVIRONMENTAL ASPECT
WATER TREATMENT
Since Metro Clark Waste Management Corporation is an engineered sanitary landfill, the only water they are to treat is the leachate produced by the solid wastes and the water used for washing the trucks of waste generators who dispose in the facility. The leachate are collected by the Drainage System installed in the landfill and are directed to the Leachate Treatment Plant. The wash water are also directed to the said plant.
In the plant are ration ponds where specialized enzymes are utilized for treatment of water. Aeration is also employed to increase the dissolved oxygen in the water. After that, the water will pass through an adsorption reed bed where fibers of soft broom are placed plus a secret ingredient discovered by their research team. After that, the water will pass through a phytofacultative pond where in heavy metals are removed by water lilies.
ENERGY SOURCE
The energy of MCWM is being supplied by MERALCO.
WASTE TREATMENT
Metro Clark Waste Management Corporation provides a sanitary landfill for all around the Philippines who comply with the requirements of RA 9003. The solid waste they generate are being landfilled, the water are treated in the Leachate Treatment Plant and air wastes are treated naturally, in the environmental buffer zone of the facility.
