Our Services

We initiate, develop, and manage sustainable projects around waste, water and renewable energy. Our team of industry experts will work closely with your team to increase efficiencies and turn your challenges around resources, energy and waste into valuable business opportunities, benefitting your organization and the environment.

What we offer

Efficiency Assessments

Our team of experts will help you to understand how efficient and circular your organization is. Through mapping your processes and material flows we can advise on areas to reduce waste, optimize productivity, save energy and reduce costs.

Project Management & Implementation

When it comes to managing a project, our team of industry experts will work with you to make the shift to more sustainable operations, ensuring implementation is on time, under budget and to scope.

Research, Feasibility & Environmental Impact Assessment (EIA) Studies

Looking to understand more about the viability of a potential project or business model, or require an environmental / social impact assessment? Our experts can assist you on a range of topics, from addressing a problematic waste stream to meeting international standards within a challenging local context.

Piloting & Prototyping

After determining the feasibility of a project, our team work with you to ensure that the concept is well tested and proven before scaling up. We conduct the required research and collect the information during the pilot to ensure you have the right data to make the best decisions.


Whether you want to inform your staff about a new waste separation program, a water efficiency project or the actions being taken to save energy, we develop custom training materials to enable the delivery of the right message to the right audience, from junior staff to senior management.


Invite us to conduct a circular economy workshop with your team to strategize how to increase resource efficiency and minimize waste. Or join one of our Industrial Symbiosis workshops to connect to other organizations in our circular economy network and benefit from synergies such as trading resources (raw materials and by-products) from your industrial process.

We are very proud of the service we provide. Read our testimonials from our happy customers.
“Tandem provided us with an excellent consultation. They went the extra mile and met with a number of organizations who were connected to the issues they were helping us with. The strategy they employed to help get these organizations on board was of great value and importance. We were very impressed by their attention to detail and strong commitment to excellent service delivery.”
James Maguires
“Tandem is our left hand in our activities, allowing us to explore areas and accomplish projects far beyond what we could do internally. Their expertise in waste management in the Zambian context, the flexibility of the team to respond to business needs, the style of the leader and his colleagues enabling people to work together, and their drive to get things done, makes them a solid and capable partner.”
Luc Syngenta Seedcare
“Tandem has been exceptionally valuable to Reciprocity in co-designing, developing and implementing two particularly complex projects in Lusaka. The projects involved identifying high impact social enterprises in Zambia, coaching teams of consultants, and supervising the delivery of successful consulting projects with these enterprises. They further assisted with recruitment, management and training of local staff over a very short period of time. The projects would not have been such a resounding success without the Tandem team!”
