You can only improve what you’ve taken the time to understand.
When you deepen your understanding of your system’s energy flows, greenhouse gas emissions and further lifecycle assessment impact categories, you uncover opportunities to avoid losses and efficiently meet emission targets. All this at a company, city, and regional level. Ready to improve your system? We know just the place to get started.
Use what you have, get what you need.
Use available data or collect new data. We will support you to do both efficiently. Getting the most out of your data is our passion and we use it vigorously to identify all of your optimization potential, whatever your circumstances. Where necessary, we’ll even guide you through bridging knowledge gaps.
Use our Tools and improve your System.
Together we will implement measures and tools to improve your performance in regard to environmental and economical performance.
Profit from our know-how:
- Increase your efficiency
- Reduce your environmental impact
- Reduce your costs
- Assess your improvement
KNOWLEDGE IS PROFIT
Make use of this opportunity and profit also from our know how. Every system offers potential for optimization.
Who We Are
The team of VIRWa has more than 40 years of experience in solid waste and resource management. Recent works have given special primarily focus on system-based analyses of wastes and resources, taking environmental impacts, such as climate change, resource depletion or soil and water contamination into account. Ultimately, every project is dedicated to finding the most cost-efficient way to reach the goals of solid waste management (protect humans and the environment), thereby pursuing multiple SDGs (Sustainable Development Goals) simultaneously.
Analysis of waste processes and systems, waste management planning, assessment of greenhouse gas emissions (at different levels), analyzing and optimizing the operation of waste-to-energy plants, analysis of refuse-derived fuels (RDFs), design and evaluation of landfill aeration projects, evaluation of landfill aftercare, industrial waste management (industrial symbiosis), analysis of material cycles (such as steel or plastics), tracing of pollutants through systems (e.g., heavy metals, POPs).
