From Waste to Resource: Shifting Paradigms for Smarter Wastewater Interventions in Latin America and the Caribbean

Resource recovery from wastewater facilities in the form of energy, reusable water, biosolids, and other resources, such as nutrients, represents an economic and financial benefit that contributes to the sustainability of water supply and sanitation systems and the water utilities operating them. Resource recovery can transform sanitation from a costly service to one that is self-sustaining and adds value to the economy. Indeed, if financial returns can cover operation and maintenance costs partially or fully, improved wastewater management offers a double value proposition.

Sludge: Types, Uses, Objectives and Methods of Removing Sludge

Treated sludge can be used for agricultural practices in home gardening, forestry, and parks. Unfortunately, sludge from treatment plants contains lower nutrient levels for nitrogen, potassium and phosphorous, than common fertilizers.

It has also been criticized for containing potentially high levels of metals and contaminants. Regardless, common fertilizers also contain varying degrees of metals and other contaminants.

Can plastic debris help pave the way to a more sustainable future?

In Indonesia, Dow worked with the government and various stakeholders to complete the first plastic road trial in Depok. Approximately 3.5 metric tons of plastic waste material were mixed into asphalt to create a 1.8-kilometer-long road, which covered a total area of 9,781 square meters. The result of the project was a highly resistant plastic waste-based road that was stronger than standard asphalt roadways.

Case Studies in Private Sector Participation: Solid Waste Management

Two case studies discuss the impacts of public–private partnership contracts in the solid waste management services. The case study in Papua New Guinea draws on the National Capital District Commission (NCDC)'s experience with contracting rubbish collection to the private sector, and underscores the importance of robust and transparent procedures for tendering and contracting. In the case study in Fiji, green waste collection in Suva has been outsourced for over 25& years, but household waste collection has never been outsourced.

Toolkit: South Africa’s Good Waste Management Practises – Lessons Learned

The intention is to facilitate information sharing and learning between municipalities. An assessment of a random sample of some of the best-performing municipalities in the country including why they do so well, would give an indication of the direction that waste management services should take towards improved service delivery. The success of some of these municipalities may be duplicated in other municipalities.

West Bank and Gaza: Solid Waste Management

Over the last decades, West Bank and Gaza have suffered due to political and economic instabilit, resulting in years of inadequate infrastructure investment and poor provision of public services to the people of Palestine. The provision of standard municipal public services, especially solid waste management, was of particular concern. In response, the World Bank Group provided an integrated solution to the client, the Joint Services Coun- cil for Hebron and Bethlehem (JSC-H&B), leading to the successful conclusion of the first public-private partnership (PPP) in the West Bank.
