The challenges today is to develop a new model of resource use which is more economical, more efficient and based on a more circular economy. Reusing materials allows less CO2 emissions, production and transportation of new resources. **With regard to adaptation and resilience, we have implemented many different solutions:** - Water recycling to limit pressure on resources and user's conflicts; - Management of wastewater systems when raining to avoid floods; - Contingency plans for the provision of essential services in case of extreme events, etc. **With regard to mitigating emissions, we have developed three circular economy solutions to reduce both its carbon footprint and that of its customers:** - Energy efficiency and heating networks; - production of renewable energy; - Recovery and recycling of materials and water **► ​Read our solutions​** [ ![](/sites/g/files/dvc2526/files/styles/content_push_teaser/public/image/2015/11/vignette-Rostock_0.jpg.webp?h=bb5118ee&itok=zzF055uv "Rostock3") ](/about-us/cop21/our-solutions/bottle-bottle-rostock-germany "Rostock, Germany") [Rostock, Germany](/about-us/cop21/our-solutions/bottle-bottle-rostock-germany "Rostock, Germany") In Rostock, Germany, Veolia is converting 1 billion plastic bottles each year into flakes that are then used to make new bottles.
