– electric and electronic waste > free of charge to the Sortti-station

– pressure impregnated wood > free of charge to the Sortti station (max. 1 cubic metre)

– waste containing asbestos > to the Ämmässuo Sortti

– Collection containers for hazardous waste are usually located in the yards of service stations or stores and are accessible during their opening hours.

Treatment companies for hazardous waste in Finland

• Akkuser Oy -Safe and efficient battery

recycling

• Fortum Oyj - provides physio-chemical

treatment for inorganic hazardous

waste, such as acids and bases.

Reception of waste

In 2017, ca. 457 000 tonnes of waste was received at the

Waste Treatment Centre

Sortti Station, operating within the Waste Treatment Centre,

receives small loads of waste as well

Ämmässuo Eco-industrial center

Waste treatment

From landfilling to waste treatment

Mechanical seperation and treatment of reusable waste fractions

- Sorting hall received and treated 17 700 tn of waste + 5 900 tn waste

from sorting stations in 2017

Mineral waste is used in landfill structures and infrastructure building at

the eco-industrial center

- Received total 119 000 tn of mineral waste in 2017

During Vantaa Energys maintenance brake municipal mixed waste is

received and bailed

- In 2017 close to 24 000 tn of mixed waste was received for bailing and

intermediate storage

In addition intermediate storage of seperately collected waste fractions

Composting in open-air stacks

First tunnel composting facility in 1998

December 2006

Biogas facility in 2015

The annual capacity is 80 000 tonnes of

biowaste and wastewater sludge, which

results in 30 000 cbm of ripe compost

Ämmässuo Waste Treatment Centre

Treatment of fly ash,

bottom ash and boiler

slag from the waste-to-

energy plant

Stabilisation and final disposal of fly ash and boiler ash

Ca. 4 100 t/a is received

Due to its high chloride content, this is hazardous waste

Stabilised with cement, finest-grained mineral material

of slag, and water. This prevents the dissolution of

detrimental substances.

Final disposal at the landfill for hazardous waste

Treatment of boiler slag

Ca. 72 000 t/a is received

Magnetic and non-magnetic metals are separated in the

treatment and put to recycling

The remaining mineral material, screened by its grain size

into separate fractions, can replace virgin mineral materials

Ämmässuo Waste Treatment Centre

Treatment of

contaminated soil

extracts

Utilisation of contaminated soil extracts as such

Principal contaminants: organic

compounds

Treatment methods: pore gas treatment

and/or composting

Heated treatment hall for contaminated soil

extracts (PIMA hall) enables all-year-round

degradation of harmful substances

Apart from the PIMA hall, there is a VOC hall

for treating soil extracts contaminated

through volatile compounds Utilised in landfill structures and in

landfill landscaping

Soil extracts contaminated by heavy

metals can also be utilised at the HSY

landfill

Ämmässuo Eco-industrial center

Landfilling

Landfill treatment and final disposal

Old landfill, 53 ha

– In use between 1987–2007

– Over 11 million tons of waste is final-disposed there

– Height of the waste fill is over 40 m

Landfill, 55 ha

– Introduced in 2007

– The first 12.4 hectares are now in use

– Municipal solid waste unsuitable for reclamation, construction waste, rejects and soil extracts are final-disposed here

– Final disposal of domestic waste was discontinued in 2016

After-care of the landfill

According to the law, a time period of at least 30 years must be reserved

for the after-care

Due to the extensive size of Ämmässuo, the need for after-care will last,

in practice, for several decades longer

The after-care includes

– Monitoring of leachate collection and sewer system and prospective

maintenance of leachate recycling for maintaining gas formation

– Monitoring of the gas collection system as a whole and pipe by pipe;

monitoring of the amount and methane-concentration of collected gas

– Monitoring of the surface insulation structures and begin prepared for

remodelling and repairing them along with the indentations

– Environment monitoring

Ämmässuo Waste Treatment Centre

landfill gas

Utilisation of gas

Formerly used as district heat at Fortum’s Kivenlahti heating plant

with a utilisation rate of 50–60%

From 2010 onwards, as electric and heat energy in the gas power

plant with a utilisation rate of ca. 90% (2017: 87%)

Improves as a CO2 neutral fuel (LFG) significantly

the utilisation of landfill and replaces fossil fuels in

energy production of the Helsinki Metropolitan Area

– The reduction of carbon dioxide emissions is conditional upon the type

of the replaceable production form

Gas power plant

Based on the gas-engine technique, strict

conditions set for the environmental permit

Production of additional electricity from the

waste heat of electricity production (ORC)

Total investments with the management

agreement ca. 15 million euros (investment

support, granted by the Ministry of

Employment and the Economy, is 22% of the

total investments)

The project has won several prizes
