Suez, as an international waste management company, is dealing with a quick and various evolution of its business regarding organic waste treatment. This is notably the case for anaerobic digestion in European countries as France and the United Kingdom, as well as in Hong Kong, North America or Australia.
Drawing on Suez’s last return of experience and developments in three countries (France, United Kingdom and Hong Kong), this presentation uses three French plants, one United Kingdom plant and one Hong Kong plant as illustration to bring forward some relevant new information on the progress and main technical issues regarding:
- The Montpellier Ametyst plant new process: Suez R&R France has developed for Montpellier Méditerranée Metropole with help of the Suez corporate research center (CIRSEE) a new optimized process that combines the production of biogas and electricity (22 GWHePA in 2017) and the production of a high quality normalized compost (33KTPA in 2017).
- The Clermont Ferrand Vernea plant: Suez R&R France is operating for VALTOM a multi-processing waste treatment centre receiving globally 200 KTPA including 20 KTPA of selectively collected bio waste (mainly green waste) that are shredded before being processed through a dry way digester and aerobically matured in composting tunnels.
- The Meta Bio Energie plant near Angers: Suez R&R France Organics is managing in the west of France a merchant plant that receives and treats 60 KTPA of organic waste, including 25KTPA of commercial (packaged) and industrial bio waste that are pre-treated, mixed and digested and lead to the production of 9 GWhePA and both liquid and composted digestate.
- The Surrey Ecopark project: Suez R&R UK will operate by end 2017 the Surrey Ecopark plant that is composed of a 55 KTPA gasifier and of a 40 KTPA capacity wet AD plant. It will deliver through co-generation of Biogas more than 12 GWHPA and 17 KTPA of dewatered digestate.
- The Hong Kong OWTF1 project: Suez R&R Hong Kong will operate by end 2017 the OWTF1 that will treat more than 70KTPA of commercial and industrial bio waste through a dedicated pre-treatment and 3 wet way digesters of 4500 m3 each. It will lead to the production of biogas and green electricity (up to 26 GWHePA) and 6000 TPA of composted digestate.
By attending this presentation, participants will better be able to:
- IDENTIFY the great variety of feedstock to treat and the main technical solutions present on the market and operated by Suez
- COMPARE the different pre-treatment solutions that can be applied or not to clean/dirty and wet/dry feedstock
- EVALUATE the respective potential of application of dry way and wet way AD technologies and consequences on water global mass balance
- APPRECIATE the global cost of treatment and the influence of green energy selling price or waste water treatment cost on this global cost
