National Institute of Science and Technology on Sustainable Sewage Treatment Plants

  1. 1. RCE Curitiba Paraná Regional Centre of Expertise on Education for Sustainable Development
  2. 2. CRIE - RCE CURITIBA - PARANÁ - BRAZIL Created in 2007 Main goal - create a task force: fostering ESD (Education for Sustainable Development) and empowering the educators to lead changes for a sustainable future The mobilization has to involve education institutions, companies and government and then flow to the community, generating a cascade effect through all levels of education ACTIVE PARTNERS: ISAE | PUC- PR | UFPR | UTFPR
  3. 3. Projects in Progress 1. Care About Water in Curitiba, Brazil: Educational and Environmental Practices at School 2. Sustainable Entrepreneurship in School 3. Ciclovida – Phase II 4. Freshwater Chondrichthyan Biodiversity and Interactions with Humans: danger under the surface? 5. National Institute of Science and Technology for Sustainable Sewage Treatment Stations – INCT ETEs Sustentáveis
  4. 4. National Institute of Science and Technology on Sustainable Sewage Treatment Plants In partnership with: UFMG, UFPE, UFRP, USP, UFCE, UFMS, ISAE Some of the institutions at the network: UTFPR, UFPR, UP, UEPG, Sanepar
  5. 5. o LA&C countries reached 86% urban coverage for sanitation; o 18 million people still practice open defecation (2.9% of the total population) o only 20% of the population have acess to some kind of improved sanitation facility The present sanitation scenario in Latin America and Caribbean
  6. 6. Urban coverage – Percentage of population by region Scenario in Brazil Sewage collected and non-treated Sewage collected and treated Individual systems Non-treated Sewage 43% 12% 18% 27%
  7. 7. Brazil existing sewage treatment plant | STPs o Design based only on environmental protection laws o No clear perception of possible financial return, social benefits and other environmental gains: expenditures with final disposal of sludge; biogas is wasted (burned into atmosphere) and the treated effluent is disposed of in receiving water bodies, many times adding up undesired residuals of pollutants and contaminants. o If well designed, built and operated, conventional STPs can achieve high removal efficiencies (OM, nutrients and pathogens), fulfilling primary goal of water pollution control.
  8. 8. Current goals Relevant aspects: o Reducing process and energy costs and GHG emissions o Improving final effluent quality Domestic sewage Water reuseSTP Energy recovery By-products recovery: sludge, nitrogen, phosphor o Increasing the efficiency of the treatment process o Recovery of: o Water o Energy o Resources
  9. 9. How INCT is doing User awareness, workers capacitation Patents, Prototypes, softwares Technical events, books, articles Basic and applied research, cooperation agreements
  10. 10. The results so far  5 workshops  1 national seminar  1 special journal  1 small course  3 technical visit  8 books chapters  15 articles
  11. 11. And maybe we might have a more sustainable sewage treatment plant
  12. 12. Thanks!
