Communication

Objective:

environmental education in order to foster the environmental awareness

Measures:

• Public information is focusing on the education of children due to the fact that they are perfect for spreading information among their families

• classic PR-work

Facts:

• 35 waste advisers, 30,000 h per year, 60,000 phone calls

• 1,000,000 visitors at our homepage per year

Waste hierarchy in EU

1.waste

prevention 3.recycling 5.

disposal

e.g. Initiative „naturally less waste“, bans on hazardous substances (e.g.. CFC, mercury)

separate collection, recycling center recycling, composting

landfilling,final sink

2.preparingfor re-use

4.other

recovery

e.g. support ofre-use and

repair networks,re-use-shops

thermal treatment,waste to energy




12

Waste prevention

• Projects – Fundingfor e.g.

– reusable cup hire system since 2005

Cups are delivered and picked up at the end of the event(system already used successfully during events such asLife-Ball, Danube Island Festival (3 Mio. visitors),European Football Championship)

prevention of:3 Mio. oneway-cups, 30 t waste, 220 t CO2

– Vienna Christmas gift bags

• Flea market („48er Basar“)– selling of re-usable goods from recycling centers

prevention of 800 t waste / year




13

Preparing for re-use

• Repair-network Vienna– Network of 50 repair-workshops for all kind of goods

• Repair-center for WEEE– Repairing and service of electric and electronic devices– Spare parts supply

• Trash design– Design products from waste materials

Strategic Environmental Assessment (SEA)

Objective:

Establishing (or updating) a Waste Management Planwith a wide consensus

• numerous experts and NGOs are involved from the very start

• intensive, time consuming process

• SEA enables to come up with sustainable solutions acceptable for everyone concerned, the city and the environment alike

Why SEA?

negative examples (no SEA)

positive examples (with SEA)

clean: 250,000 t waste are transferred to clean energy

High-Tech for environment

Viennaon the way to sustainable waste managementwith

• strategic long term environmental planningby means of modern planning instruments (eg. SEA)

• emphasis on communication

• self-sufficiency and short distances for waste-treatment

• maximum of output from waste (material recycling, energy recovery)
