Title: Sustainable technologies
1Sustainable technologies
- GREEN BUILDINGS
- HEATING COOLING
- WASTE RECYCLING
- WATER WASTEWATER
- ENVIRONMENTAL ENGINEERING
Sweden fully embraces green technologies
2Green buildings
- Green building material, energy efficiency, waste
collection and utility organization are main
areas involved. - Wood building technology, low energy housing
solutions (passive houses) are forefront areas in
Sweden. - Long tradition in energy efficiency work both in
industry and construction with many leading edge
companies.

6Building in wood a Swedish specialty
- Every 7th new Swedish home based on wood
construction (multi-family buildings),
construction under way all over the country - Know-how to build tall constructions (8-10
floors) as well as special-purpose buildings and
bridges - Advanced research at a number of Swedish
universities - Välle Broar in Växjö 1,200 apartments in
Swedens largest wood-constructed neighborhood
Limnologen, part of Välle Broar ,Växjö
Benefits environment, speed, cost, quality
7Heating cooling
- Heat pumps Sweden has the highest number of
installed geothermal heat pumps in the world and
is also home to some of the largest producers.
This has created a platform for independent
researchers and developers since the 1970s. - District heating Sweden is the world leader in
district heating and Swedish carbon dioxide
emissions have thereby dropped by 20. Now 80 of
the Swedish district heating is based on energy
that would otherwise have gone to waste. - District cooling Sweden is a pioneering country
in district cooling and first plant was in
operation 1992. Now 30 plants producing district
cooling and Swedish district cooling companies
have laid a strong foundation for building
systems in the form of pipelines.
8Geothermal heat a brilliant, efficient idea
- Even climates without a lot of sun suffice to
store enough heat energy underground. The heat
pump can be used for both heating and air
conditioning. - It takes only one part electricity to produce
three parts heat - RPM control reduces energy consumption
- New technology yields hotter water and faster
heat for less money - Geothermal heat reduces annual electricity
consumption by 50 to 75 - Remote monitoring and control can be managed
over the Internet
9District heating principle
District heating plants utilise a wide variety of
fuel types and take advantage of energy that
would otherwise go to waste, such as waste heat
from industrial processes, forestry waste and
energy recovered from rubbish and waste. The
technology is uncomplicated and very reliable.
10Sweden is the world leader in district heating
- Sweden is the world leader in district heating.
Consistent and relatively high environmental
taxes on fossil fuels and openness to new
solutions in the energy sector have driven
technological progress and sharply reduced the
use of fossil fuels. - The transition from individual systems to large
district heating plants has reduced emissions of
nitric oxides, sulphur dioxide and particulates.
Swedish carbon dioxide emissions have dropped by
20. - A long history of building knowledge about how
common systems should be built and maintained - Energy companies with tremendous financial
endurance - Four-fifths of the heat used in Swedish
district heating networks is based on energy that
would otherwise have gone to waste
11District cooling a technology with minimal
environmental impact
District cooling is based on the same principles
as district heating. Water is chilled and then
distributed in a pipeline to homes, offices,
industrial buildings and other spaces that need
air conditioning. The cold water is pumped
around in a closed system and used to cool the
air circulating in the buildings ventilation
system. The same water is then piped back to the
production facility to be rechilled.
12District cooling is making strides
- Swedens first district cooling plant went
operational in 1992. Today, there are about
thirty plants producing district cooling in
Sweden. Studies show that total demand for
district cooling equals about 2000-5000 GWh. - The growing numbers of computers in the workplace
and the realisation that comfort cooling
increases productivity have brought greater
demands for a comfortable climate at work. As a
result, the need for eco-friendly and
cost-effective comfort solutions is increasing
every year and the market is growing rapidly. - 10 of global electricity production is used
for cooling - 16 of US electricity production is used for
cooling - More than 80 of buildings in the US and Japan
are air-conditioned. The figure is less than 50
elsewhere in the world, but is rising fast - The EU expects district cooling to provide 25
of the requirement by 2020
13Waste recycling
- Collecting, handling, biological treatment,
recycling and depositing - Efficient systems for collection and sorting
strongly reducing landfills - Developed systems for "waste to energy" has given
waste a value - Smart solutions to local transportation, heat and
energy use

17Stockholm A green leader among world capitals
District heating produces about 75 of the heat
required to keep Stockholm warm. The high
percentage has made Stockholm a green leader
among world capitals. Stockholm is growing and
district heating is growing right along with it.
Högdalenverket is one of the biggest district
heating plants in Europe. The household waste
produced by the people of Stockholm is burned
here and converted to electricity and district
heating. Over the years, this has contributed to
sharp reductions in emissions of carbon dioxide
and other harmful substances. Every year,
Högdalenverket takes in 500,000 tonnes of
household waste and 200,000 tonnes of sorted
industrial waste, which is converted to 450 GWh
of electricity and 1,700 GWh of district heating
for a quarter million Swedes.
18Water wastewater
- Economizing, local and central sewage systems
- Wastewater treatment for both industry and homes,
and sludge treatment - Waste water (grey water) to drinking water
- Black water / sludge to energy
19Swedish model for water supply and sewage
20Integrated water management
- Drinking water supply
- Swedish companies and municipalities have worked
within this area for over 140 years! Export
started 1903! In the early days focus was on
providing freshwater and fire fighting. In
addition to the 2000 public water plants in
Sweden this know how has been exported to more
than 100 countries. - Wastewater services and systems
- Sweden has one of the most far-reaching effluent
standards in the world for treated wastewater.
Sewage treatment plants were introduced as early
as the 1930s. Mechanical treatment was followed
by biological treatment in the 1950s and
chemical treatment in the 1970s, reducing
discharges of the nutrient phosphorus and more
recently nitrogen. - Bio gas energy production
- The first commercial biogas recovery plants was
built in Sweden in the early 90s. This product
evolved from the broad experience within energy
systems. The RD within the area has given new
state-of-art low emission and high-yield
products, which covers all the stages from design
and construction to turnkey renewable fuel
production plants.
21Environmental engineering
- Analytical services and similar within the area
of environment and natural resources exploration - Great market for technical services with advanced
environmental legislation - Urban and industrial system application knowhow
- Massive investments in natural resource
exploration in Scandinavia and the Barents Sea
Region
22Great demand for environmental engineering
know-how
- Strong industrial base in heavy engineering
automotive, energy, engineering, metals, mining,
and pulp and paper - CSR issues highly prioritized, Swedens
multinationals invest heavily to improve
environmental performance - Large project investments under way (wind power
build-up, expansion of mining capacity, etc)
23Gate to the Barents Sea Region
- One of the worlds richest areas for natural
resources - 25 of world oil and gas reserves in Barents Sea
- Target oil and gas explorers, energy companies
and metals and mining companies in Sweden,
Norway, Finland and Russia - Sweden natural base
- Culturally easy to do cross-border business
