Integrated Waste Management System (IWMS)

1.1 Lifecycle-based Integrated Solid Waste Management
The first concept of ISWM is based on lifecycle assessment of a product from its production and consumption point of view (Figure 1.1). The reduction in consumption, and utilization of discarded products within the production system as a substitute for new resources, can lead to reduced end-of-cycle waste generation; thus, less efforts and resources would be required for the final disposal of the waste.

1.2 Generation-based Integrated Solid Waste Management
The second concept of ISWM is based on its generation from different sources including domestic, commercial, industrial and agriculture. This waste could be further classified as hazardous and non-hazardous waste (Figure 1.2). The former has to be segregated at source and treated for disposal in accordance with the strict regulations. 3R approach (reduce, reuse and recycle) is applicable both at source as well as at the different levels of solid waste management chain including collection, transportation, treatment and disposal.

1.3 Management-based Integrated Solid Waste Management
The third concept of ISWM is based on its management (Figure 1.3) which includes regulations and laws, institutions, financial mechanisms, technology and infrastructure, and role of various stakeholders in the solid waste management chain.

2. Waste Transportation
WMC (Pvt) Ltd. hires from reputable companies third party audited vehicles having FTW “fit to work” status as and when requires, WMC also ensures that the drivers and their companions engaged for the waste transportation are PPE clad have trainings pertained to Safe Driving and Road Safety besides the reasonable knowledge of HSE and have inductions about the sensitivity of activity with a satisfactory track record of Driving rules and Policy compliance /work (Driving) experience, awareness about ROW (Right of Way).

Besides the above Waste specific Van of WMC (Pvt) Ltd. with specially designed canopy shuttles between collection and disposal points to collect the waste from the identified location and transport the accumulated waste consignment to deliver on disposal facility and equipped with:
3. Waste Disposal

Since its inception in 2002 the WMC has been accomplished a number of challenging waste disposal projects in conjunction with compliance of local and international recognized HSE norms & rules pertained to variety of Hazardous and Non Hazardous Liquid and Solid waste disposal and therefore not only won the prestigious NFEH Excellence awards twice in the stated category in 2007 and 2009 as an accreditation for its meritorious services to Environment and Health by National Forum for Environment & Health but also won the trust of esteemed clientele engaged in a variety of businesses all over the country.

WMC provides total solution for the disposal of wastes that are environmentally safe to the utmost possible level. These wastes, if disposed off in a conventional manner, cause or may cause hazards to human health and environment. A team of well qualified and experienced professionals, the core of WMC, provides well thought of solutions keeping in view the different dimensions of waste management and their impacts on every component of the environment. All environmental aspects, including the national legislative requirements, are considered while conceiving the disposal strategy.

National and international standards are taken into account for the analysis of wastes and estimation of pollutants during the disposal options. Services of authentic and competent institutes/companies are procured, as and when required, for testing and analysis or other requirements. In short, the WMC is a group of experts committed to provide innovative waste management solutions, from handling to disposal of wastes, utilizing the best available techniques that are cost effective at one end and acceptable in the domain of environmental protection at the other end.

4. Waste Assessment Planning

Assessment of Waste Management (SWM)

Solid waste management may vary from country to country and city to city. In most countries, the local governments are responsible for municipal solid waste management; however the other two i.e. industrial and hazardous solid waste materials are the responsibility of the national government. In some places, the local governments with different departments, manages all the three kinds of wastes individually. If there is only one institution or department, responsible for all types of SWM, then it may be considered as a single management system. However, if there is more than one institution responsible for different types of solid waste or waste generated by different sources, then it is considered as separate management systems. Therefore, it is recommended to collect the data and information separately, for different types of systems even if there is some overlapping in terms of regulations and laws, financial mechanisms, technology and infrastructure and stakeholder participation.

It may also be noted that management systems may be evolved over a period of time depending on the variations in solid waste, political and administrative systems, socioeconomic situation, and geo-climatic conditions. Hence, it is useful to capture the evolving process with respect to laws, institutions, financial mechanisms, technology and infrastructure and stakeholder participation.

Waste Assessment Planning

5. Organization of Guidelines

This is the second set of guidelines that focuses on the assessment of solid waste management systems. The first set, which is available separately, focuses on the quantification and characterization of solid waste streams from different sources.

The assessment of the management systems may follow the following roadmap:

Coverage:

In case of SWM, before starting to assess the management systems, it is important to define them. There may be more than one management systems to address solid waste from different sources and/or different types of solid wastes. SWM systems include regulations and laws, institutions, financial mechanisms, technology and infrastructure and stakeholder participation in solid waste management chain.

Assessment of individual management systems:

If there is more than one management system to handle solid waste, either from different generators or different types of solid waste (hazardous and non-hazardous), then the individual systems should be analyzed separately and the data so obtained could be compared to see their similarities and differences. For general purpose, the guidelines classify solid waste management in three systems, viz.: municipal solid waste, industrial solid waste, and hazardous solid waste. However, there might be fewer or more systems available in a particular city or country. To analyze solid waste management systems, the data and information is required to be collected on the following aspects:
6. Importance of Data Collection and Analysis

Development of Integrated Solid Waste Management (ISWM) Plan demands the assessment of current solid waste management systems apart from their quantification and characterization which would further be useful for:
7. Monitoring and Analysis

Flowchart for Data Collection and Analysis

It may be helpful to create a flowchart for data collection and analysis for all the stages of IWMS to avoid duplication of efforts and to assign a clear role to the team members who are responsible for the same.
