Building zero-waste cities through sustainable transformation

In Pakistan’s Twin Cities of Islamabad and Rawalpindi, inadequate city waste management threatens both human health and the environment through pollution of land and water. These cities generate large volumes of solid waste every day, yet only a portion is properly collected and recycled. Improper disposal has caused significant environmental degradation and public health risks, while the consequences of poor waste management systems extend downstream—impacting the 220 million Pakistanis who rely on the Indus Basin, as well as the marine ecosystems of the Arabian Sea.

Urgent action is needed to transform waste practices, curb greenhouse gas emissions from open dumpsites, and reverse environmental degradation. By reimagining waste as a valuable resource rather than a burden, we can move closer to creating zero-waste cities—paving the way for a cleaner, healthier, and more sustainable future.

 

Transformation through collaboration

Through the Shelter program, Arcadis collaborated with UN-Habitat to develop and secure funding for an integrated waste management solution in the Twin Cities. Arcadians from Portugal, the Netherlands, Australia, and Canada worked on-site to define technological strategies and provide investment guidance.

During the mission, the Arcadis team partnered with a wide range of local stakeholders, including the Ministry of Climate Change, the Islamabad Capital Development Authority, the Rawalpindi Waste Management Company, the Dr. Akhtar Hameed Khan Memorial Trust, and private businesses. This inclusive, two-way consultation process ensured that local expertise and context informed every decision—an essential step toward achieving a truly sustainable transformation.

Developing a holistic solution

The collaboration between Arcadis, UN-Habitat, and regional stakeholders resulted in a comprehensive approach to city waste management—integrating modern waste technologies across both neighborhood and city scales.

The proposed waste management system includes Integrated Resource Recovery Centres (IRRCs) and Materials Recycling Facilities (MRFs), with potential future expansion through engineered landfills.

• IRRCs operate at the neighborhood level, collecting and sorting household waste into organic, recyclable, and residual streams. Organic waste is converted onsite into compost that can be sold to improve household and agricultural soil quality.
• MRFs work at the city scale, receiving and processing recyclables from urban areas. Both systems help divert waste from open dumpsites, returning organic and recyclable materials to the value chain and supporting a circular economy.

As the waste management system matures, a key next step will be the development of an engineered landfill to safely dispose of residual waste and prevent groundwater contamination. Together, these innovations will establish a foundation for zero-waste cities in Pakistan.

 

Improving quality of life

This integrated, holistic solution for Islamabad and Rawalpindi is designed to enhance surface and groundwater quality, reduce greenhouse gas emissions, improve public health, and create new employment opportunities. By reintegrating recyclables into the economy and advancing sustainable transformation, the Twin Cities are setting a precedent for waste management solutions that elevate communities and improve quality of life for millions.
