Past Projects

WASTE Advisers in Action across Malawi

Much of our success in the work we do is a result of a desire to understand the needs of our communities and then to develop innovative and sustainable solutions. We’re committed to work with and strengthen local institutions to see them fulfill their mandates. Have a look at some of projects below.

SSLA in Blantyre

The Sanitation Service Level Agreements (SSLA) is a large project in Blantyre City covering the whole sanitation value chain from Containment to Re-use. The project is funded by Bill and Melinda Gates Foundation and DFID. During this project we brokers relationships between the Council and Private operators across the sanitation value chain.

On the Containment component WASTE and the Blantyre City Council with investment from the private sector are targeting have constructed or rehabilitated 42 Public Conveniences. Contact the Council if you are interested in a license to operate a Public Convenience or to partner to build a new facility. We have also trained masons to do low-cost latrine construction in the most economical way in a model called Community Pay Toilets. This also builds for future demand for the emptying services as as almost 40% of latrines can't be emptied due to low quality. 


Transport is the pit and septic tank emptying businesses. As just over 10% of the City of Blantyre is connected to the sewerage network, this is a vital part for sanitation and yet currently most of these services happen illegally and unregulated. The project has introduced new technologies and are formalizing relationships between existing operators and the Blantyre City Council.  If you are in need of an emptying service, please contact the Blantyre City Council on the toll free number 526 or 80001001. They will log your request on a WhatsApp group for the Pit Emptying Association. 

The project developed pilot business models on the treatment and re-use of faecal sludge. These include co-composting, briquettes, earth worms and biogas digesters. The most significant of these is the co-composting which is integrated with the municipal market waste to improve solid waste management as well. Co-Composting offers a sustainable solution for waste management, but also offers a value product for the farming community whose farmlands has been depleted of nutrients and carbon content through unsustainable farming. Lillie's Organic Compost is currently operating the Limbe site. The briquettes has been carried into our current EU Project.

Great Results


The Emergency Sanitation Project (ESP) increased the global understanding
of current and future emergency sanitation solutions and proposed new concepts and modular technologies for safe excreta disposal and hygiene in emergency settings that are applicable in a variety of situations and contexts. The video clip was the first trial the MDU, a very innovative pit emptying technology. For more information see 

Testing the Necessities



The aim of the project was to develop a functional field test kit for the microbial quality control of faecal sludge and the monitoring of sludge treatment plants. A team from the Austrian University of Natural Resources and Life Sciences led by Johannes Bousek did the field trails and trained up our team to be able to continue with the lab. 

Progress toward SDG 6


In this project we partnered with Welthungerhilfe to built and rehabilitate 80 community water points, 26 school and 9 market place toilets facilities in Zomba, Liwonde and Mangochi. The infrastructure was the smaller component of this project as each of these facilities needed a sustainable management system. In addition to these sanitation containment facilities, the project also trained masons to build low cost latrines, supplied vacuum tank technologies and built treatment facilities for the city councils.
