‣ By 2010, at the latest, food <strong>waste</strong>, <str<strong>on</strong>g>and</str<strong>on</strong>g> c<strong>on</strong>sequently also equivalent <strong>waste</strong><br />

from food industries etc., shall be recycled through biological treatment.<br />

The objective refers to <strong>waste</strong> not mixed with other types of <strong>waste</strong>, which<br />

subsequent to treatment is of sufficient quality that it is suitable for crop<br />

producti<strong>on</strong>. (AÖS., 2009)<br />

The most important treatment methods for <strong>waste</strong> are:<br />

‣ Material recycling<br />

‣ Biological treatment<br />

‣ Waste-to-Energy<br />

‣ L<str<strong>on</strong>g>and</str<strong>on</strong>g>fill<br />

Hazardous <strong>waste</strong> as a special type of <strong>waste</strong> can be treated with any<strong>on</strong>e of the<br />

above methods. Either <strong>on</strong>e or a combinati<strong>on</strong> of them can be used . Biological<br />

treatment can be implemented <strong>on</strong>ly through anaerobic digesti<strong>on</strong> or<br />

composting. The Anaerobic digesti<strong>on</strong> process produces the biogas which in<br />

turn can be used as vehicle fuel. The total quantity of biogas produced from<br />

<strong>waste</strong> treatment with the (AD) process, is equivalent to 30 milli<strong>on</strong> liters of<br />

petrol. The final product of the (AD) called digestate comprises an excellent<br />

nutrient. The composting process produces a high quality fertilizer called (the<br />

compost) which is used as a soil improver in parks, gardens <str<strong>on</strong>g>and</str<strong>on</strong>g> ground<br />

installati<strong>on</strong>s. (AÖS., 2009)<br />

The Waste incinerati<strong>on</strong> process is also widely used in Sweden. It is used for<br />

producing energy from <strong>waste</strong> (thermal energy <str<strong>on</strong>g>and</str<strong>on</strong>g> electricity). Every year it<br />

produces heating which corresp<strong>on</strong>ds to the need of 810,000 <strong>household</strong>s,<br />

approximately 20% of all the district heating produced. It also produces<br />

electricity in a quantity which corresp<strong>on</strong>ds to the need of more than 250,000<br />

houses. Finally the l<str<strong>on</strong>g>and</str<strong>on</strong>g>filling treatment method is still been used for these<br />

<strong>waste</strong> which cannot or should not be recovered or treated in another way (such<br />

as some types of hazardous <strong>waste</strong> or ash). Through l<str<strong>on</strong>g>and</str<strong>on</strong>g>filling, <strong>waste</strong> is kept in<br />

a l<strong>on</strong>g-term safe way, <str<strong>on</strong>g>and</str<strong>on</strong>g> the treatment method is c<strong>on</strong>trolled by a strict<br />

regulatory framework. (AÖS., 2009)<br />

The choice of the organizati<strong>on</strong> of a <strong>waste</strong> management system, represents a<br />

decisi<strong>on</strong> of the local authorities . This possibility of municipal self-government<br />

is laid down in the Swedish c<strong>on</strong>stituti<strong>on</strong>al law. The local authorities can choose<br />

management mode or municipal undertakings, separate or joint with other<br />

municipalities. Cooperati<strong>on</strong> am<strong>on</strong>g the Municipalities, is also possible with a
