Resource wisdom has many benefits
• The first that comes to mind is the ability to save on natural resources,
materials and energy.
• Resource wisdom also creates new business and jobs.
• This slide show presents the results of an impact assessment of selected
resource-wise measures implemented in Jyväskylä.
• The assessment covers local added value generated by new business, as well as
permanent effects on employment and greenhouse gas emissions. Cost savings
and investment needs were also assessed.
• The main goal is to reveal the size of the impact of various measures.
• This slide show begins with a summary, followed by a more detailed description
of each measure. Further details on the calculation assumptions are provided in
the slide show annexes.

The measures and their impact
The results

6. © Gaia6
1. Reduction of leftover food
Starting point: Approximately 11% of
food produced in institutional kitchens is
thrown away. The amount of food that goes
to waste could be reduced by selling
leftover food, which would also help to
reduce the amount of biowaste.
Outcome: The amount of leftover food
generated by institutional kitchens
providing free meals in the Jyväskylä
region (schools and other educational
institutions) will be reduced by selling
leftover food to external customers. Meals
will be sold for a nominal price that covers
the cost of bread, spread and beverages. It
is estimated that this would reduce the
amount of food wasted by 50,000 meals a
€

2. Production of local food
Starting point: Primary production
in Central Finland is currently valued at
€261M, while food industry production
totals €438M. Depending on the line of
business, primary production has a 70–
84% self-sufficiency rate, while the food
industry has one of 15–88%.
Outcome: An increase in locally
produced food so that half of the raw
materials and food stuffs acquired from
elsewhere in Finland and from abroad
are replaced by produce from Central
Finland. This would increase the value
of Central Finland's primary
production by 10% and regional food
industry production by 12%.

3. Production of biogas and soil from biowaste
Starting point: The amount of
biowaste currently collected in the
Jyväskylä region is approximately 13,000
tons a year. The collected biowaste is
used in soil production at a composting
plant run by local company,
Mustankorkea Oy.
Outcome: More efficient collection of
biowaste and the expansion of the
collection area will increase the amount
of recovered biowaste by some 5, 000
tons a year. A new biogas plant will start
producing biogas from biowaste.
Nutrient-rich residues will be used by the
composting plant in the production of
soil.

INFOSHEET: Waste recovery at Mustankorkea
At present, the composting plant of Mustankorkea Oy handles 30,000 tons a year
of separately collected biowaste and manure, and sludge from wastewater
treatment plants. Together with peat and other soil materials, the composting end-
product is used as a raw material for soil products. In 2013, the total amount of soil
products sold came to around 27,000 tons.
In the future, Mustankorkea may also begin the production of biogas from
biowaste (current amount some 13,000 tons, but there is potential for 5,000 tons
more), manure and sludge (current amount some 17,000 tons, but there is
potential for 10,000 tons more). These higher amounts of recovered materials will
be based on the more efficient collection of biowaste and the expansion of the
collection area.
Biogas production would multiply the added value derived from the plant’s refining
processes, while significantly enhancing its future potential for soil production.

4. Production of transport fuel from biogas
Starting point: Total consumption
of biogas in Central Finland is around
30 GWh a year. While biogas is mainly
used for heat and electricity
production, some is already an
ingredient in the production of
transport fuel.
Outcome: Central Finland will
exploit half* of the technical and
economic potential of biogas, i.e. 245
GWh. New production will be entirely
focused on the further processing of
biogas into transport fuel.

There will be enough
biogas to cover the fuel
consumption of around
17,000 private cars.
The reduction in the use of
foreign fuels will help
improve Finland’s trade
balance by approximately
€16M a year.

5. Increasing the use of wood fuel
Starting point: In 2012, total
consumption of wood fuel in Jyväskylä
was 1,270 GWh. This was 20% more
than in 2010.
Outcome: The annual use of wood
fuels will be increased by 1,000 GWh.
Compared to 2012 consumption levels,
this would mean eliminating the use of
coal (160 GWh), and reducing oil
consumption by 50 GWh and peat
consumption by 790 GWh. This will
mainly be achieved through an
investment that will enable the 100%
conversion of the Keljonlahti power
plant to wood fuel-based production.

6. Energy efficiency of buildings
Starting point: Around 2,440 GWh of
energy was used to heat buildings in
Jyväskylä in 2012. Electricity
consumption by residential buildings
and agricultural activities came to
approximately 450 GWh.
Outcome: Energy efficiency will be
improved by 11% for heating and 7% for
electricity consumption, to correspond
to the average values for various types of
building monitored by Motiva through
energy audits. The interest-free payback
time on investments has been 2.7 years
on average. €

INFOSHEET: Improving the energy efficiency of outdoor lighting
A practical trial was implemented in Jyväskylä, in which the outdoor lighting system
of one housing company was replaced with a new LED lighting solution. With the old
system, annual electricity consumption was roughly 6,700 kWh. Following the
installation of a LED solution, electricity consumption fell to 1,700 kWh. This
amounts to 5,000 kWh in annual savings – 75% less than at the starting point.
The overall cost of renewing the lighting system was approximately €5,400, including
design (€400) and installation (€5,000). Annual savings in electricity totalled
approximately €600, making the interest-free payback time on investment around
nine years.
Were the average emission coefficient for electricity supply in Finland to be applied in
this case, changing the outdoor lighting system would equate to a reduction in
greenhouse gas emissions of around 1.5 kt CO2 eq a year.

7. Optimisation of soil material transport
Starting point: Each year, some
860,000 tons of soil material are
transported in Jyväskylä. They travel
an average distance of 18 km. 50% of
these journeys are made by empty
vehicles.
Outcome: The introduction of smart
programming and a material bank will
help make soil transportation more
efficient. As a result, less temporary
storage, less loading and fewer
vehicles will be needed, and reuse will
increase. Driving with empty loads will
be completely eliminated.

8. Reduction of private car use
Starting point: Private car use has increased by
10 percent in Jyväskylä in the last 20 years. The car
is the preferred mode of transport for 60-70% of
Jyväskylä’s residents.
Outcome: The share of trips made by car will be
reduced, while walking, riding a bike and using
public transport will become more popular. 80% of
the employees of the City of Jyväskylä will change
their behaviour to comply with their employer's
commuting guidelines. These guidelines
recommend walking or using a bike when
commuting less than 5 km. In addition, a campaign
will seek to increase the popularity of public
transport from 5% to 7%, in line with the objectives
of the City of Jyväskylä.

9. Reduction of water consumption
Starting point: Average daily water
consumption is 155l, of which 40-50l is
heated water.
Outcome: Various measures will be
introduced to reduce water
consumption among people living in
apartment blocks, based on a reduction
target of 20%. Options include
encouraging behavioural changes
through the installation of water meters
and increased awareness, or switching
bathroom and toilet fittings for models
that save on water and energy.

INFOSHEET: Planning with energy and climate issues in mind
Designing and comparing energy solutions during planning will help to save money
and make land use more efficient. If all planning in Finland followed the example
of Skaftkärr in Porvoo, municipalities would have saved up to two billion euros by
2020.
Efficient and energy-wise planning could help municipalities to lower their
investments in local infrastructure construction by 170 – 240 million euros a year,
which equates to roughly five per cent of total municipal investments. Annual
savings in transport fuels in 2020 would amount to 80 – 110 million euros, or
around 160 euros per resident moving into a new housing area.
These figures are based on the assumption that all new construction areas in
Finland will be planned in an energy-wise manner over the next ten years.

Assumptions, calculations
Background materials

General assumptions
• Meta-analysis was used in this case, i.e. the impact assessment was mainly based on data obtained
from previous assessments, which was supplemented where necessary. The goal was to
demonstrate the scale of various options.
• In assessing each option’s potential, the goal was to achieve a realistic and feasible outcome. For
this reason, account was not taken of the full potential of each measure in every case. Instead, only
the realisable potential was highlighted.
• Assessment of the employment impact took account of permanent jobs only. The investments
have also had a temporary positive employment impact, but this was excluded from the reported
results (in some cases, more detailed information was provided on the employment impact of
investments by more precise reporting on the calculation assumptions and initial data).
• In cases (1-5), which involve the creation of new, local added value, the annual added value of
regional production was calculated. In cases (6-9), where the consumption of energy, fuel or water
was reduced, calculations were performed to determine the value of annual savings.
Calculation assumptions and
initial data

21. © Gaia21
1. Reduction of leftover food
Raw materials
• According to estimates, under current conditions one fifth of the food produced by institutional kitchens goes to waste. Leftover food,
which could be reduced by selling leftover meals, is thought to account for 11% of this (see Sitra report). According to calculations, the
amount of leftover food could be reduced by 50,000 meals in Jyväskylä. This is based on an assumed emissions reduction of 1.3 kg of
CO2 per 300 g meal.
Implementation
• Some food destined for the (biowaste) bin could be served to customers for a nominal fee outside normal catering times.
Investments
• No new investments required. These activities will be run use current facilities and equipment, by existing personnel.
Added value to production
• Let us assume that the price of a meal is €1.5. This would cover the cost of the bread, spread and beverages. According to estimates,
50,000 meals could be sold each year. Assuming that the cost is €50/ton of biowaste, the biowaste-related cost reductions would be
marginal. It is also assumed that the reduction in biowaste transportation would not affect costs.
Employment impact
• No need for additional workforce – operations will continue using existing personnel.
CO2 calculations
• An emissions reduction is assumed of 1.3 kg of CO2 per sold 300 g meal. It is also assumed that the reduction in biowaste
transportation would not affect CO2 emissions. Let us also assume that the customers buying the leftover meals arrive on foot or
using the same mode of transport that they would have used if they had gone elsewhere instead.
Other
• We may also assume that the purchase of leftover meals would have no significant impact on demand for other restaurant services.
The sale of leftover meals should be limited to leftover food from the institutional kitchens of schools and educational institutions that
provide meals free of charge. This would help to prevent customers of regular lunch services from switching to after-service meals in
the hope of saving money.

2. Production of local food
Raw materials
• At present, primary production in Central Finland is currently valued at €261M and food industry production is worth €438M. Depending on the
line of business, the self-sufficiency rate is 70–84% for primary production and 15–88% within the food industry (source: Ruralia Institute,
Reports 93).
Application
• The quantity of local raw materials used in local food production and food service and retail activities could be significantly increased. This would
have an impact equivalent to the entire share of GDP accounted for by primary production, the food industry and food service and retail activities.
There would also be an employment impact.
Investments
• Not included in the assessment
Added value to production
• Calculations of the value added in production are based on the assumption that 50% of the maximum demand potential presented in Ruralia's
report, which does not include imports from elsewhere in Finland or from abroad, would be realised. In the calculation assumptions, the resulting
impact on Central Finland’s GDP due to value added in primary production would be 10% (€28M) , and that of the food industry would be 12%
(€49.5M). We could also assume that 40% of ingredients used by the food industry would be local, while the corresponding figure for publicly
operated kitchens would be approximately 50%. This would mean that half of the raw materials currently acquired from elsewhere in Finland or
from abroad would be replaced by local raw materials.
Employment impact
• In primary production, the employment impact would be 10%, or an additional 383 person-years, and in the food industry, 8.5 %, or an additional
477 person-years. This would account for half of the likely employment impact of the Ruralia project if the maximum employment potential were
realised. (Data on Central Finland)
CO2 calculations
• Let us assume that the changes in CO2 emission levels arising from changes in land use are not significant. At national level, the CO2 emission
impact of changes in transportation and logistics could be negative, due to Finland’s inefficient logistics chain (compared to large chains). A more
precise assessment of the changes in CO2 emissions would require more detailed initial data on the origins and mode of transportation used for
food imported to Central Finland, and the locations and types of food production that would replace the current situation.
Other
• In geographical terms, our scenario is limited to Central Finland. There would not necessarily be any justification in limiting the definition of
locally produced food to that produced in the Jyväskylä region or province. Besides, it may prove challenging to obtain initial data on the basis of

3. Production of biogas and soil from biowaste
Raw materials
• An additional 5,000 tons of biowaste could be collected every year (13,000 tons of biowaste are currently handled at Mustankorkea
each year). This estimate is based on information provided by Mustankorkea' s Managing Director Esko Martikainen.
Application
• All collected biowaste (18,000 tons a year) is primarily used in the production of biogas, whose end-product is methane, which can
in turn be used in energy production or as transport fuel. Approximately 15 GWh of methane is generated each year (this
calculation is based on data from Wabio on biowaste sorted at the creation site, TS 35%; VS/TS 80%). At the composting plant,
reactor residues are utilised in soil production.
Investments
• The investment calculation is based on the calculation guidelines given in the Wabio brochure. The need for pre-treatment and the
cleaning of raw gas have a bearing on the size of the investments. The price range was determined bearing this in mind, while
taking account of the alternative factors presented above.
Added value to production
• The value of the methane generated in heat production would be €45/MWh (Statistics Finland), and as a transport fuel it would
total €90/MWh (VAT 0%) (selling price includes VAT 24%: €1,505/kg CH4; source: Gasum). The value of soil is €15/ton (source:
Mustankorkea’s price list). These represent the high and low ends of the price range. Energy is a dominant factor.
Employment impact
• VTT's estimate of 0.7 person-years/GWh was used here. This took account of permanent jobs only. In addition, investments have
a significant positive but temporary impact on employment (a rough estimate would be a few dozen person-years).
CO2 calculations
• Biogas is used to replace either engine fuel or diesel fuel as a transport fuel, or LFO in heating (emission coefficient: 265
gCO2/kWh).
Calculation assumptions and
initial dataPremise

4. Production of transport fuel from biogas
Raw materials
• Tähti et al. (Potential for biomethane and hydrogen production in Finland, 2010) have estimated that biogas production in Central
Finland has a technical and economic potential amounting to 490 GWh. The theoretical potential is 1,200 GWh.
Application
• Let us assume that half of biogas production’s technical and economic potential is realised, i.e. 245 GWh. This would best be done
by making use of the more profitable half, with most production being concentrated in large plants. The result would be lower unit
costs. The resulting biogas would be further processed into transport fuel.
Investments
• Assessment of the investments was based on the investment required for previously completed plants (Labio Oy, former Kujalan
Komposti, 50 GWh – €17M). The results were also compared with the report by Saana Ahonen: ”Biogas as a transport fuel –
regional transport biogas supply chain in Central Finland”. These factors were used to establish a price range, while bearing in
mind the aim of using the alternatives with the greatest potential profitability.
Added value to production
• Biogas produced as a transport fuel was valued at €90/MWh (VAT 0%) (sales price, VAT 24% incl.: €1,505/kg CH4; source:
Gasum).
Employment impact
• We used VTT's estimate of 0.7 person-years/GWh. This took account of permanent jobs only. In addition, the investments would
have a significant positive but temporary impact on employment. The assessment took no account of this.
CO2 calculations
• Biogas is used to replace either engine fuel or diesel fuel as a transport fuel (emission coefficient: 265 gCO2/kWh)
Other
• The number of vehicles covered by the amount of transport fuel produced from biogas is given as a rough estimate, calculated on

5. Increasing the use of wood fuel
Raw materials
• The total amount of wood fuel used in Jyväskylä amounted to 1,060 GWh in 2010 and 1,270 GWh in 2012 (source: Jyväskylän
Energiatase energy balance report). The power company Jyväskylän Energia also aims to increase its use of wood fuel. Here, the
assumption is that the use of wood fuel can be increased by another 1,000 GWh per year from its 2012 level. This will be achieved
through an investment that enables Keljonlahti to increase its wood fuel use to 100%.
Application
• Compared to 2012, coal (160 GWh) will be completely replaced by wood and 50 GWh of oil consumption. The remaining share
(790 GWh) will replace peat (as a reference figure, Keljonlahti used 940 GWh of peat in 2012). It was assumed that the total
amount of fuel would remain the same.
Investments
• Investment in Keljonlahti approx. €55M (source: Tero Saarno). The investments made also include some written-off costs.
Added value to production
• Calculation of the value added to production in the region involved totalling the change in value of the domestic fuels used. The
price of wood and peat, based on data from Statistics Finland (in December 2013: wood: €21/MWh, peat €18/MWh). Use of wood
is growing; peat use is diminishing.
Employment impact
• On the basis of the employment estimates given by the Pellervo Economic Research Institute (wood/wood chips, the following
figures have been calculated: 0.15 person-years/GWh; peat: 0.088 person-years/GWh); The employment impact of wood use
would be positive, while that of peat use would be negative.

6. Energy efficiency of buildings
Starting point
• A total of 2,440 GWh of energy would be used to heat buildings and the electricity consumption of housing and agriculture would
total 450 GWh (Jyväskylän energiatase 2012 energy balance report).
Energy saving potential
• Based on more than 1,000 energy review reports, Motiva has estimated that potential savings in heating would total 11% and
electricity savings would come to 7%. This would give an average payback time on investment of 2.7 years.
Investments
• The value of investments in the above-mentioned targets was calculated on the basis of the Motiva reports, with a payback time of
2.7 years. To verify the results, the limit values were broadened and the calculations repeated with a payback time of 3.5 years.
Value of energy savings
• The value of energy savings was calculated on the basis of consumer prices (Statistics Finland consumer prices for heating energy,
December 2013). Electricity €150/MWh, district heating €76/MWh, oil €108/MWh, wood pellets €60/MWh.
Employment impact
• Not included in the assessment. The employment impact of the investments was evaluated as being in excess of 1,000 person-
years. However, this figure was not included in the report due to the principle that only jobs permanent during the period under
review would be included.
CO2 calculations
• The electricity calculations were based on the five-year national average (Statistics Finland, Tilastokeskus, benefit sharing scheme,
223 g/kWh), the district heating calculations on the CSR Report of power company Jyväskylän Energia (210 g/kWh), and the light
fuel oil (LFO) calculations were based on information provided by Motiva (267 g/kWh). The breakdown of heat consumption was
based on the Jyväskylän energiatase 2012 energy balance report.

7. Optimisation of soil material transport
Starting point
• 860,000 tons of soil material is transported within Jyväskylä each year. The average distance of each journey is 18 km and a typical
load of soil weighs 17 tons. Source: Jyväskylä 75
Savings potential of transports
• Journeys by empty vehicles will be eliminated.
Investments
• During resource-wise practical trials, the cost of investing in the development of a material bank and programme would be
€20,000 - 100,000.
The value of savings in transportation costs
• The consumer price of diesel, €1.6/l, was used to calculate the value of savings in transportation costs. Financial savings in fuel
costs were taken into account. Fuel consumption while driving with an empty load totals 0.27 l/km (VTT's LIPASTO emission
calculation system). Possible savings related to temporary storage areas and the reuse of material have not been factored in.
Employment impact
• Not included in the assessment. The possible employment impact may result from i) changes in transportation used, or ii) program
maintenance.
CO2 calculations
• Driving with an empty load generates 864 g CO2-eq/km (Sources: Jyväskylä 75 and VTT's LIPASTO emission calculation system).

8. Reduction of private car use
Starting point
• In Jyväskylä, as a share of all modes of transport, public transport accounts for 5%, with 18,000 trips made each day. For
commuting trips of less than 5 km, the initial data was obtained from the Jyväskylä Region Travel Survey (Commute intelligently
II, 2013), commissioned by the City of Jyväskylä. According to this survey, nearly one in two workers use a private car to travel to
work. The City of Jyväskylä employs 6,500 people, of whom 50% have a commuting distance of less than 5 km. Of these employees,
30% use a car to travel to work. The average commuting distance used in the calculations was 3 km.
Potential for reduction
• The assumption is that 80% of city employees covered by the commuting guidelines will change their behaviour. In addition,
campaigning will be used to increase the popularity of public transport from 5% to 7%, in line with the objectives of the City of
Jyväskylä. The potential exists to increase the occupancy rate of public transport, eliminating the need to add bus services in order
to implement this measure.
Investments
• No significant investments.
Value of savings
• Bus fares will generate additional income for the bus company. The calculations were derived from the average fare determined on
the basis of the price of a single fare for an adult and children, €2.5. The average distance travelled was 7 km. The occupancy rate of
buses would increase from the current level (15 persons/bus) to 21 persons per bus. These calculations were based on car fuel
consumption of 6.5 l/100 km and a fuel price of €1.7/l. Introduction of this operating model would require guidelines for city
employees and the acquisition of certain equipment. Positive impact: there would be a reduction in traffic congestion, noise and
accidents, and less need to invest in new lanes on roads. In addition, there would be positive health impacts, such as fewer
particulate matter emissions discharged into the air we breathe, and improved health among commuters who would use their own
muscle power to get around.
Employment impact

9. Reduction of water consumption
Starting point
• The starting point is the average water consumption of Finns, 155 l/day, of which 40–50 l is heated water (Motiva, 2013).
Approximately 58,600 people live in apartment buildings in Jyväskylä.
Potential for saving water
• Motiva has estimated that the installation of water meters would reduce water consumption by 15-20%. In the practical trials
conducted under the Towards Carbon-Neutral Municipalities (or, HINKU) project, alternative bathroom and toilet fittings helped
to reduce water consumption by 16%. Based on these figures, the estimated potential saving in water would be around 20%.
Investments
• No investments.
Value of the water saved
• The calculation of the value of the water saved was based on lower water rates and water heating costs, using the consumer price of
water (the consumer prices of Jyväskylän Energia, December 2013). According to the cost structure applied to water management
in Jyväskylä, 20% of water rates are not based on fixed costs.
Employment impact
• No significant employment impact.
CO2 calculations
• These figures were calculated on the basis of savings related to the energy required to heat water (district heating coefficient 210
g/kWh, CSR Report of Jyväskylän Energia), to pump raw water (electricity need 0.00042 kWh/l, Jyväskylä 75, and 223 g/kWh in
emissions), and for wastewater treatment (0.47 kg CO2/m3, Tenhunen 2000).
