2 The Role of Environmental Taxes Applied to Municipal Solid Waste
ARC is a public enterprise within the Planning & Sustainability Department of the Government of Catalonia.
• Competences – Municipal waste – Industrial waste – Construction waste and debris – Manure & Livestock (jointly
with Agriculture Department) – Sanitary waste and – Soil recovery

ARC has own competences on waste generated in Catalonia and also on all waste which are managed within Catalonia

What is Biowaste?
Waste Framework Directive (2008/98/EC) defines bio-waste as: “biodegradable
• garden and park waste,
• food and kitchen waste from households, restaurants, caterers and retail premises
• comparable waste from food processing plants”.
6
Biowaste definition in Catalonia
The Organic Fraction of the Municipal Solid Waste: OFMSW
Garden and Park Waste
7
Objectives and Targets regarding Biowaste: EU
Art. 9: reduce the generation of food waste in
primary production, processing and manufacturing, retail and other distribution of food, restaurants and food services and Households by half
Proposal for Amendment of Framework Directive 2008/98/EC
Art. 11: Increase preparation for reuse and
recycling of MSW in to at least 65% in weight by 2030
Proposal for Amendment of Directive 1999/31/EC on the landfill of waste
Art. 5: reduce the amount of MSW
landfilled to 10 % of the total MSW generated by 2030
Circular Economy Package

Objectives and Targets regarding Biowaste: Catalonia
PRECAT 20 General Program for Waste prevention and management and resources in Catalonia 2020:
Strategic objectives: Promote the consideration of
waste as resource Prevent climate change Soil protection and improvement Waste prevention Promote preparation for reuse Increment material recovery with
view to circular economy Abandon gradually landfilling and
incineration of recoverable waste
Quantitative targets: Reduction of 50% food waste
production, reference year 2010 in retail, catering and households
Material recycling: 60% in weight of biowaste in 2020
End of 2016: reduction targets for primary and agrifood sector, including wholesale distribution
Qualitative targets: Biowaste: contaminant materials < 10
% in 2020

Necessity for Bio-waste Prevention
Framework Directive 2008/98/EC
Waste Prevention Highest Priority
However...
Mediterranian conditions: • Poor soils • Erosion • Desertification
sustainable option: • Separate collection • Biological treatment • Application to soil of Bio-waste

Necessity for Bio-waste prevention: Food waste
Social and ethical impact Nearly one billion people suffer from hunger worldwide
Economic impact Total economic loss: 841 M€ in Catalonia (2010)
Environmental impact Greenhouse gas emissions: 520.700 tonnes of CO2 eq in 2010 in Catalonia (equivalent of emissions from 20.300 motor vehicles throughout their working life)

Food-waste prevention in Catalonia
The Diagnosis of Food Waste in Catalonia (2010)*
* Waste from wholesale distribution, the agrifood industry or the primary sector not considered in the study
15
Food-waste prevention in Catalonia
The diagnosis proposed actions for following sectors: • Administration • Production and manufacture • Distribution • Restaurants and catering • Homes

Food-waste prevention in Catalonia
Action: Awareness raising 6th European Week for Waste Reduction (LIFE Project) Held from 22nd to 30th November 2014 all over Europe Actors involved: public authorities, companies, schools,
associations and citizens. Results for 2014: 11,995 actions in 34 European regions
(871 Catalan actions)
Action: Support for local projects 750.000 € in economic subsidies and technical support (2015):
•Catalan Food Bank Foundations (since 2007)
•Local bodies and non-for profit organisations (since 2010)
Collaboration with other institutional initiatives

Bio-waste treatment in Catalonia:
Compost
28
Bio-waste treatment in Catalonia: Anaerobic Digestion+Composting
PROs Requires less area Allows better management of
emissions / odors Allows recovery of energy
(biogas) Fuel for vehicles CONs High costs (investment
/management) More sofisticated and sensitive
technology Requires high input quantities Requires homogeneous input More feasible on the industrial
scale
4 Facilities
29
Bio-waste treatment in Catalonia: Composting
PROs Simple, robust technology Flexibility (capacity/modules) Biological process less
complicated Process allows and requires
input of woody materials (green waste)
Lower costs (investment/management) than AD
CONs Slower process

Bio-waste treatment in Catalonia: Composting Diversity of Settlements and topography
Diversified approach to biological treatment
Home and Communty Composting •2014 : 423 Municipalities - 5.970 t of Biowaste treated •Investment and operational cost very low •Proximity - less waste transport •High identification of the citizens
31
Bio-waste treatment in Catalonia: Composting
Small decentralised facilities, of simple and robust technology for high quality bio-waste • Adequate for smaller waste amounts (<2.000 t)
• Lower investment and operational costs
• Relatively high surface demand
• High quality bio-waste required
Diversity of Settlements and topography
Diversified approach to biological treatment
32
Bio-waste treatment in Catalonia: Composting
Centralised big and medium sized composting facilities • Adequat for large quantities of biowaste
• Higher investment and operational cost
• Relatively low surface demand
• Housed facilities require air treatment (odours)
