Public Scoping for Proposed Engineered Sanitary Land Fill

[Audio] Good [morning/afternoon] everyone. Thank you for being here today. I’m Mark Anthony Caneba, and I will be presenting the Public Scoping for the Engineered Proposed Sanitary Landfill. This presentation aims to give you a clear overview of the project, its environmental considerations, and gather your valuable feedback, which is essential in the planning and permitting process..

[Audio] Before we proceed with the technical details of the project, it’s important to first understand the purpose of today’s public scoping. This activity aims to: Inform and consult the public about the proposed sanitary landfill project, including its scope, location, and design. Identify potential environmental and social concerns that may arise during construction and operation. Gather comments, suggestions, and recommendations from stakeholders like you — inputs that will be carefully considered in the Environmental Impact Assessment or E-I-A process. This ensures that the development of the project is transparent, participatory, and inclusive. Stakeholder engagement is a key component of responsible and sustainable development. Your involvement as members of the community, local authorities, and concerned organizations helps us: Encourage community involvement, ensuring that the voices of those who may be affected by the project are heard and valued. Promote environmental and social responsibility, by identifying possible impacts early and addressing them effectively. Enhance the acceptability of the project, as transparency builds trust and leads to better cooperation between the proponent and the community. We believe that working together is the best way to achieve a balanced and well managed development..

[Audio] The core objective of this project is to promote sustainable land use through the redevelopment of a previously excavated 4-hectare quarry site. Instead of leaving this degraded area idle and potentially hazardous, we are transforming it into an engineered sanitary landfill to address the current and future waste management needs of the locality (City of Calamba). But our vision does not end there. Once the landfill reaches its full capacity, we will implement a systematic filling, grading, and rehabilitation process. The ultimate goal is to convert the area into a fully developed and environmentally safe golf course or botanical park—a transformation that aligns with ecological restoration, recreational development, and economic upliftment of the community. This approach not only solves a pressing problem—waste disposal—but also offers a long term, sustainable solution that benefits both the environment and the people..

[Audio] The proposed Engineered sanitary landfill is a 4-hectare engineered waste management facility designed to safely and systematically dispose of residual solid waste. It will be developed on a former quarry site, which has already undergone excavation—making it ideal for this type of development. The site was selected based on technical studies that considered soil stability, surface water, fault line, accessibility, and minimal impact to sensitive ecosystems. This Engineered sanitary landfill will be operated under strict environmental controls, in compliance with the Ecological Solid Waste Management Act (RA 9003) and denr Administrative Orders to prevent contamination of groundwater, minimize greenhouse gas emissions, and ensure long term site stability..

[Audio] Here is an overview of the proposed project: Project Title: Proposed Engineered Sanitary Landfill Development Proponent: Green Republic Inc. Project Type and Description: This is a Category 3 Engineered Sanitary Landfill, fully compliant with RA 9003, also known as the Ecological Solid Waste Management Act of 2000. It is specifically designed to accommodate residual wastes from the City of Calamba. The landfill is projected to manage an estimated 157 tons of waste per day (T-P-D--), ensuring proper disposal of non recyclable and non compostable waste in accordance with environmental standards. As for the project timeline, we anticipate a 4 to 6-month period for permit acquisition, followed by 6 to 8 months of site development. Once operational, the facility is expected to function for 2 to 3 years, depending on waste volume and other environmental factors. This project is committed to promoting environmental protection, public health, and sustainable waste management for the benefit of the community..

[Audio] Let me now walk you through the main components and operational process of the proposed engineered sanitary landfill. Each part of the facility is designed to ensure safety, efficiency, and full compliance with environmental standards. Entrance and Weighbridge This is the primary control point for vehicle entry and waste delivery. All incoming trucks are weighed to track the volume of waste entering the facility. Waste Receiving Area and Inspection Zone Here, all waste loads are subject to visual inspection to check for unauthorized materials, such as hazardous waste, electronic waste, or recyclable items that should not be landfilled. Disposal Cells Waste is deposited into engineered landfill cells, each of which is lined with an impermeable geomembrane and compacted clay. Cells are segmented and filled in phases, ensuring better control over waste placement and environmental impact. Leachate Collection and Treatment Facility This system collects leachate—the liquid that drains from waste—and treats it onsite to prevent contamination of soil and groundwater resources. Gas Venting and Collection System As waste decomposes, it generates gases like methane. This system monitors, captures, or safely vents these gases to minimize greenhouse emissions and explosion risks. Drainage and Stormwater System A well designed drainage system is in place to prevent flooding and erosion, especially during heavy rains. This protects both the facility and the surrounding environment. Final Cover System Once a cell reaches its capacity, it is sealed with layers of topsoil and vegetation. This promotes stabilization, prevents odor and leachate formation, and prepares the area for eventual rehabilitation and post closure use. All these components work together as part of a controlled and environmentally sound waste management process..

[Audio] The Engineered Sanitary Landfill Process begins at the entrance gate, where all incoming waste trucks undergo strict documentation and are guided toward the Weighbridge. Here, each truck is weighed to record the volume of waste delivered, ensuring proper monitoring and control. After weighing, trucks move to the inspection area, where the waste is checked for prohibited or hazardous materials. Once cleared, they proceed to the active landfill cell. The active cell is lined with engineered protective barriers, including compacted clay, H-D-P-E liner, and geotextile, to prevent soil and groundwater contamination. Waste is then unloaded, spread, and compacted using heavy equipment. Compaction helps reduce the volume of waste and increases the stability of the landfill. At the end of each day, the working face is covered with daily cover soil to control odor, prevent pests, and limit exposure to the environment. As waste decomposes, leachate is generated. This is collected through a leachate drainage system and transferred to the Leachate Treatment Facility, where it is treated to meet environmental standards. At the same time, landfill gas, primarily methane, is captured through a network of gas wells. This gas can be flared or converted into energy, contributing to sustainability efforts. Once the cell is filled, it is capped with a final layer of soil and planted with grass or vegetation to blend with the environment and prevent erosion. Through this systematic process, the Engineered Sanitary Landfill ensures waste is managed in a way that is safe, sustainable, and environmentally responsible. Facility, while landfill gas is captured through gas vents for flaring or possible energy recovery. Finally, once the cell is full, it is capped and rehabilitated with topsoil and vegetation. This process ensures proper waste containment, minimizes environmental impact, and supports long term site stability..

Potential Environmental and Social Impacts.

[Audio] As part of the Environmental Impact Assessment (E-I-A--) process, we have identified potential environmental and social impacts that may arise during the construction and operation of the proposed engineered sanitary landfill. These impacts include: 1. Air Quality Dust and odor emissions may be generated during waste delivery and handling. Mitigation measures will include dust suppression, daily waste covering, and odor control systems. 2. Water Quality There is a risk of leachate contaminating surface and groundwater if not properly managed. This will be addressed through an engineered leachate collection and treatment system and regular water quality monitoring. 3. Soil Contamination Improper handling of waste could result in soil degradation. Use of impermeable liners and proper containment will prevent this. 4. Noise and Traffic Increased truck traffic may cause noise and congestion, especially during peak delivery times. Traffic flow management and designated routes will be implemented to minimize disruption. 5. Biodiversity and Ecosystem Disturbance Minimal impact is expected, but any disturbance to nearby flora and fauna will be closely monitored, and buffer zones will be maintained. 6. Health and Safety Risks Exposure to waste and vectors could pose risks to workers and nearby residents. Strict health and safety protocols, P-P-E usage, and pest control measures will be in place. 7. Social Acceptability Community concerns such as visual impact, property value, or stigma may arise. These will be addressed through continued stakeholder engagement, transparency, and the long term rehabilitation plan, which includes conversion into a green space or golf course and or botanical park. The purpose of identifying these impacts is not to raise alarm, but to show our commitment to proactive planning, risk management, and mitigation..

Mitigation and Enhancement Measures.

[Audio] To address the potential environmental and social impacts identified, the project will implement a comprehensive set of mitigation and enhancement measures. These are designed to ensure that operations remain safe, sustainable, and compliant with environmental regulations. Air Quality Control: The landfill will be covered daily with soil to minimize dust and odor. Odor neutralizers and a misting system will be used at key areas to reduce foul smells. Water and Leachate Management: A double layer lining system—including compacted clay and H-D-P-E geomembrane—will prevent leachate from seeping into the soil. A dedicated leachate collection and treatment plant will handle all liquid waste. Groundwater monitoring wells will be installed to track any possible contamination. Noise Reduction: All equipment will be fitted with silencers or noise suppression systems. Operational activities will be scheduled during daytime hours only, to avoid disturbing nearby communities. Soil and Land Management: To prevent erosion, we will construct ripraps and apply grass cover in exposed areas. Progressive rehabilitation will be conducted as each cell is filled, helping stabilize the land and prepare it for future use. Biodiversity Protection: Buffer zones around the facility will be reforested with native species. The project will avoid ecologically sensitive areas and preserve surrounding flora and fauna. Community Protection: The project includes health and safety programs for both workers and nearby residents. Environmental monitoring reports will be regularly shared with stakeholders to ensure transparency. A grievance redress mechanism will be in place to receive and resolve any community concerns throughout the life of the project. These measures reflect our commitment to responsible waste management and environmental stewardship..

[Audio] One of the most important environmental safeguards in this project is the multi layer barrier system located at the bottom of the landfill. This system is engineered to prevent soil and water pollution by ensuring that no contaminants can escape into the ground. Let me walk you through the layers from bottom to top: Compacted Soil Base – This provides a stable foundation to support all the layers above it. Clay Layer – Acts as a natural barrier, helping to block liquid (leachate) from seeping downward. Plastic Liner (H-D-P-E-) – A high density polyethylene (H-D-P-E-) sheet that is fully waterproof and designed to prevent leakage. This is one of the most critical protective layers. Fabric Layer (Geotextile) – Placed over the plastic liner, it serves as a protective cushion that prevents punctures or damage from gravel or heavy equipment. Gravel Drainage Layer – This layer allows for efficient collection and flow of leachate, the liquid that drains from the waste. Leachate Collection Pipes – These pipes carry the collected leachate to an onsite treatment facility, ensuring it does not pollute groundwater or nearby water bodies. Together, these layers form a comprehensive and compliant protection system, in line with environmental regulations and best practices in sanitary landfill engineering..

[Audio] To further strengthen the health and sanitation controls within the landfill, the project incorporates an eco friendly vector control system using drones and biodegradable insecticides. The drones are equipped for precision spraying, allowing wide coverage over the landfill while avoiding direct worker exposure to hazardous zones. They follow automated flight paths via G-P-S--, ensuring consistent and time efficient operations. For pest control, we’re using biodegradable agents including: Bacillus thuringiensis israelensis (Bti) – a biological larvicide that safely targets mosquito and fly larvae, Pyrethrin based sprays – derived from chrysanthemum flowers for quick knockdown of adult insects, and Neem oil – a natural growth regulator and insect repellent. This method ensures minimal environmental impact, worker safety, and public health protection. Most importantly, it complies with all relevant denr and P-C-O regulations, contributing to a modern, sustainable landfill operation..

[Audio] In addressing the challenge of foul odor in landfill operations, we’ve adopted an eco friendly and technology driven approach to meet both operational and community expectations. First, we employ drone assisted spraying to apply odor neutralizing agents evenly across wide landfill areas. This method not only improves coverage but also minimizes workers’ exposure and reduces the need for intensive manual labor. The odor neutralizers used are environmentally safe. We use bio enzymatic sprays that break down odor molecules through natural bacterial action, and plant based deodorizers like those derived from citrus or eucalyptus oils. Notable examples include Ecosorb, FreshWave, and Bio Zyme. Lastly, daily waste covering with soil or organic matter helps contain odors and gas emissions while also discouraging pest activity. Combined, these solutions ensure our operations remain compliant, community friendly, and sustainable..

Community Engagement and Livelihood Development.

[Audio] As part of Green Republic Inc.’s commitment to Corporate Social Responsibility, we place great importance on community engagement and livelihood development. We believe that sustainable development goes hand in hand with empowering the communities we serve. That’s why we ensure regular consultations with our host barangays and local stakeholders. We listen to their concerns, gather insights, and build partnerships to promote inclusive growth. One of the key highlights of our C-S-R program is the livelihood support we provide. We offer training and job opportunities to local residents, especially in areas such as: Eco brick and compost production using recyclable and biodegradable materials, Upcycling workshops, where waste materials are turned into usable household items, and Work opportunities in our Materials Recovery Facility (M-R-F--) and other support functions within the landfill operation. In addition to this, we prioritize local hiring and conduct skills development programs to prepare community members for roles in waste management, environmental monitoring, and site maintenance. Ultimately, our goal is to uplift the quality of life in the surrounding areas while promoting environmental awareness and sustainability. Green Republic doesn’t just manage waste—we help build self reliant, environmentally responsible communities..

[Audio] On site, we will use a Vertical Baler System for recyclables such as paper, plastic, and cardboard. This equipment: Reduces waste volume, Enhances segregation, Supports compliance with RA 9003, and Improves transport efficiency for recyclables..

[Audio] To enhance waste diversion and resource recovery, the proposed engineered sanitary landfill will integrate a pyrolysis plant as part of its sustainable waste management strategy. How It Works: Pyrolysis is a thermal decomposition process conducted at 300–700 degrees celsius in the absence of oxygen, targeting non recyclable, carbon based waste such as: Plastics Rubber Biomass By Products and Their Uses: Pyrolysis Oil – Used as an industrial fuel substitute Syngas (Synthetic Gas) – Utilized for on site energy generation Char – Can be repurposed as construction filler or soil enhancer Environmental Controls: Cyclone Separators Gas Scrubbers Carbon Filters Continuous Emissions Monitoring System (C-E-M-S-) to ensure real time compliance with air quality standards Regulatory Compliance: RA 9003 – Ecological Solid Waste Management Act.

[Audio] Another sustainability initiative within the project is the integration of a Concrete Hollow Block or C-H-B production facility that utilizes selected solid wastes as alternative materials for construction. Instead of relying entirely on traditional resources like cement and sand, this facility will repurpose non biodegradable and inert wastes—including crushed glass, plastic flakes, fly ash, rice husk ash, and even demolition debris. These materials will be processed and blended to form durable C-H-B-s-, offering a dual benefit: reducing the volume of landfill bound waste, and conserving natural raw materials. This initiative directly supports RA 9003, or the Ecological Solid Waste Management Act, by promoting waste diversion, materials recovery, and green construction practices. Not only is this approach environmentally responsible, it also creates a cost effective building material that aligns with the project's long term sustainability goals and the principles of a circular economy. In summary, this C-H-B production system transforms what was once waste into a valuable construction resource—helping build not just structures, but a more sustainable future..

Leachate Collection and Treatment System.

[Audio] One of the key environmental safeguards of the facility is its Leachate Management System. Leachate generated from the landfill will be efficiently collected through a dedicated Leachate Pumping Station. This system ensures that all liquid waste is properly managed from the source. The collected leachate will then be transferred to our on site Leachate Treatment Facility, where it will undergo a comprehensive treatment process to meet the regulatory standards set by the Department of Environment and Natural Resources (D-E-N-R-). Once treated, the clean effluent will be directed to an internal holding pond, where it will be stored and later reused for various operational activities within the landfill—such as dust suppression and irrigation of green buffer zones. This approach not only ensures compliance with environmental laws but also promotes sustainable water management practices by maximizing water reuse within the facility..

Dedicated Access Road Plan.

[Audio] To support smooth operations of the proposed sanitary landfill and to address concerns related to traffic congestion, we have included the development of an Alternate Roadway Plan. This includes constructing a dedicated access road that will serve as an exclusive route for trucks transporting waste. By diverting these heavy vehicles from the main roads—especially those passing through residential or high traffic areas—we can significantly reduce traffic buildup, improve public safety, and minimize the impact on the local community. Furthermore, we will coordinate closely with the Local Government Units and the Department of Public Works and Highways to ensure that the design and implementation of this road complies with all regulations and supports future infrastructure plans..
