PPI Qualification in Solid Waste Management, Treatment and Disposal
PPI and its key staff has proven experience in Solid Waste Management, Treatment and Disposal in Pakistan as follows:
A: Establishment of Strategy/Guidelines for Solid Waste Management in Pakistan
Our Proprietor, Engr. Saadat Ali has prepared strategy/guidelines for Solid Waste Management in Pakistan as follows:
- Present status of Solid Waste Management in Pakistan and Strategy for its improvement.
- Guidelines on solid waste disposal and landfill establishment
- Guidelines for Incineration
- Model Hazardous Waste Management Facility in Islamabad.
The strategy and guidelines can be seen on the website: http://www.environment.gov.pk/EA-GLines/SWMGLinesDraft.pdf
B: Solid Waste Characterization and Generation Studies
The estimation and the prediction of municipal solid waste generation play an important role in solid waste management. PPI has developed a reliable model for calculating and subsequently predicting the aggregate impact of economic trends, population changes, and recycling impact on solid waste generation.
The waste characterisation and generation study is conducted on sample preparation based on quarter coning technique as recommended by Japan International Cooperation Agency.
The Waste Characterization Study do provide an estimation of total solid waste generation and its characteristics, quantities of recyclable materials (cardboard, paper, plastics, metals, aluminium, glass, inert material etc. in the waste stream.
Furthermore, the quantities of waste into different types is worked out i.e., biodegradable and non-biodegradable; recyclable, compostable and inter materials; combustible and non-combustible materials.
The waste characterization study do provide necessary inputs for the design of Material Recovery Facility, Compost Plant, Bio Gas Plant, Waste to Energy and Sanitary Landfill.
Some of the projects are listed below:
- Waste Amount Characterization Survey in Sargodha, Muzaffargarh, Dera Ghazi Khan, Bahawalpur, Rahim Yar Khan for M/s Tractebel Engie, EDCM Consultant for PICIIP Project
- Waste Amount Characterization Survey of Sukkur, Larkana and Hyderabad for Sindh Solid Waste Management Board, Karachi

D: Need Assessment for Solid Waste Management System
The need assessment of the existing Solid Waste management System do cover following aspects:
- Estimation of solid waste generation per day
- Human resource requirement;
- Technical aspects of existing solid waste generation, collection, storage, transportation and disposal;
- Social aspects specially the role of scavengers;
- Environmental aspects; and
- Financial aspects.
The need assessment of existing solid waste management do provide necessary output specification for the proposed Integrated Solid Waste Management Plan.
E: Integrated Solid Waste Management Plan
PPI has proven experience of preparation of Integrated Solid waste Management Plan for sustainable municipal waste management which is based on following guiding principles:
- Assessment of SWM regulations, policies, institutions, and systems for municipal, hazardous industrial and infectious hospital wastes.
- Perform in–depth field assessment of physical infrastructure, systems relating to waste segregation, recycling, transportation, treatment and disposal.
- Assessment of quantity and characterization of solid waste projections for 30 years.
- Review of current and planned private sector interventions, including the activities of the informal private sector.
- Technical analysis and identification of institutional, regulatory and physical improvement options, in particular, to allow the option of private sector participation in the SWM services.
- Consultations with stakeholder, government, civil society, scavengers and the private sector to reach a consensus on priority sector actions.
- Formulation of ISWM plans for the City Administration which includes, a strategic development framework, recommendation for infrastructure and service improvement, an indicative implementation schedule, cost estimates with financing plan, human resource development, participation of private sector in ISWM service delivery etc.
The significant components of ISWM Plan do include, Capital Resources – Vehicles and Plant; Capital Resources – Property; Human Resources; and Management Procedures
Some of the Solid Waste Management Plans prepared by our team are as follow:
- Integrated Solid Waste Management Plan for Nawabshah City, District Shaheed Benazirabad, Sindh for PPP Unit, Government of Sindh, Karachi
- Solid Waste Collection, Transportation and Disposal System for Bhalwal Industrial Estate Sargodha for EA Consulting (Pvt) Ltd., Karachi
- Solid Waste Management Plan of Bahria Lifestyle, Mouza Lohi Bher, Islamabad Expressway, Zone V, Islamabad for Bahria Town Private Limited
- Solid Waste Management Plan of Bahria Enclave, Islamabad for Bahria Town Private Limited
F: Selection of Site for Construction of Sanitary Landfills
PPI has investigated and identify potential sites for construction of sanitary landfills in Pakistan.
Pakistan Environmental Protection Agency has prepared (draft) guidelines for Solid Waste Management in Pakistan which also contains guidelines on solid waste disposal and landfill establishments. Similarly, the Sindh Devolved Social Services Program, Government of Sindh has prepared guidelines for the identification and establishment of a Landfill site at TMA/District Level, Sindh, Pakistan.
All the potential site selection are considered against the established criteria for construction of sanitary landfills in Pakistan:
- Geo-technical and Hydrological Investigation: soil condition, water table
- Environmental: Landfill gas management, Odor, nuisance, Local ecological conditions, Risk to groundwater contamination, Proximity to water courses, Occurrence of flooding
- Socio-economical: Life, capacity, land value/use, public acceptability, property lines, archaeological cultural sites
- Technical Operational: Cover material availability, Access Road, Distance from the waste consumption, Proximity to airports
- Investment/Operating costs: Comparison of capital and operational cost estimates
The detailed analysis of all potential sites are prepared on the basis of above-mentioned criteria and the best site is selected for the construction of sanitary landfill.
Once a suitable site is selected for construction of sanitary landfill then detailed investigation are carried out as follows:
- Hydro-geological assessment of groundwater and unsaturated (vadose) zone conditions, and groundwater quality;
- Geotechnical surveys of surface geologic materials for suitability as landfill foundation and as low-permeability clay liming and landfill cover materials;
- Surface drainage analysis;
- Seismic and slope stability assessments where required.
The design inputs for construction of sanitary landfill are established on the basis of analyses of the above mentioned site investigations.
Projects:
Some of the projects are listed below:
- Topographic Survey of Integrated Solid Waste Management Facility at Nawabshah City for PPP Unit, Government of Sindh, Karachi
- Geotechnical Investigation for Integrated Solid Waste Management Facility at Nawabshah City for PPP Unit, Government of Sindh, Karachi
- Hydrogeological study of Integrated Solid Waste Management Facility at Nawabshah City for PPP Unit, Government of Sindh, Karachi
- Seismic Analysis of Integrated Solid Waste Management Facility at Nawabshah City for PPP Unit, Government of Sindh, Karach
G: Manual for operation of Sanitary Landfill
PPI has prepared operational manual for sanitary landfill facility, providing guidance on the operations of each of the facility over the long term as follows:
