We bridge innovation, implementation and impact in biowaste management
Eclose works with entrepreneurs, implementing organisations and international institutions to design scalable biowaste management systems across diverse contexts.
Our approach emphasises operational robustness and contextual adaptation, particularly in tropical and emerging market environments.
What we do and how we work
Eclose supports initiatives from concept to operation
Assess & Plan:
Building the right foundation
Feasibility assessments
Waste stream and market analysis
Technology selection
Business model development
Project roadmaps and scaling strategies
Design & Develop:
Turning concepts into operational systems
Facility design
Process and operational workflow design
Standard Operating Procedures (SOPs)
Equipment selection
Monitoring systems
Commissioning plans
Implement & Grow:
Supporting successful operation and long-term performance
Team training
Training of trainers
Facility commissioning
Operational support
Process optimization
Long-term technical backstopping
Our work is structured, evidence-based and designed for long-term operational stability.
We typically engage in clearly defined phases:
Context and feasibility assessment
System design and operational structuring
Implementation support and capacity building
Performance monitoring and optimization
Strategic positioning and investment readiness analysis
This phased approach ensures technical robustness while aligning with local institutional and economic realities
Academic Roots
Founded as a spin-off from applied research at Eawag, the Swiss Federal Institute of Aquatic Science and Technology, Eclose operates at the interface between science and practice.
Our academic origins inform our analytical rigour and evidence-based approach.
We continue to collaborate with universities and research institutions to translate scientific insights into operational models and policy-relevant knowledge.
Eclose has supported initiatives across diverse cultural, climatic, regulatory, and market environments
