Legal Framework

Generally all nations have adopted lawsto protect the environment and humanhealth, but they very often haven’ttaken measures to generate economicbenefits that push towards wastemanagement systems to reduce theamount of waste disposed in thelandfills.

In substance they are not considered thehidden cost paid by the environment.




URBAN PLANNING

LOW DEMOGRAPHIC DENSITY

HIGH DEMOGRAPHIC DENSITY




Urban Planning

The main urban elements usefull to design the SWM are:• demographic data;• distribution and typology of civil settlements

(households per housing unit);• toponomy of the area (cartographies, road

list);• road routes• distribution and typology of not household

activities;• seasonal flows of tourist or daily flows of

employes

SWM STATUS ANALISYS

Existing Transference Waste Plan;

Location of landfills in use;

Existing process of waste sorting, recycling or reuse;

Analysis of any existing markets of the wastecollected materials, transport methods, prices;

Analysis of local industries that could potentially useraw materials from the differentiated waste

Actual service costs divided between costs ofcollection transport and disposal




PLAN DESIGN

The plan design has to define:

• which types of waste is appropriate differentiate;

• in how many flow lines is appropriatedifferentiate;

• amount of waste to be collected by typology;

• vehicle and equipment required;

• human resources required;

• financial and economic resources necessary tosupport the process.




PLAN DESIGN

The draft plan developed on the basicstatistical data is the tool to verify thefeasibility and sustainability of the newcollection system.

TWO REAL CASE - RE.VI.ME. PROJECT OPERATIONAL PLAN FOR LA

HABANA AND SANTO DOMINGORE.VI.ME. project has developed two differentoperational SWM plans:

• Santo Domingo Ciudad Colonial-Home sortingwaste collection with bags of different colors;

• La Habana Centro Historico- Collection with binsfor not householder activities.

These two operational plans can and should beintegrated for both partners in order to develop asingle plan of services for all users of the collectionareas.

CRITICAL ISSUES

The main problems that emerged more clearly fromthe experiences that are maturing are:

-lack of economic lever determined by the low cost oflandfilling;

-lack of economic lever linked to incentives toutilities;

-difficulty to transfer the new cultural model relatedto recycling to the population and to the managers ofthe business of the area;

-lack of infrastructures and plants necessary tomanage the sorting waste collection.




CRITICAL ISSUES

The waste sorting collection undoubtedly increases the costs ofwaste disposal.

The Caribbean countries, like most emerging economies, have lowcost of landfilling which effectively determines a critical issues ofthe feasibility of sorting collection. This is essentially due to thefact that landfills are not controlled and the environmental costsare "hidden".




CRITICAL ISSUES

The differentiation of the waste requires theestablishment of plant necessary for the treatment ofdifferentiated waste in order to determine thepossibility of recycling the materials in a productioncycles. Mainly there is the need to:

• selection and sorting centres to separe and reducein volume for waste packaging fractions;

• treatment plants of the organic fraction

In particular the realization of a plant for the organicfraction determines the possibility to collect andrecycle approximately 50% of the waste




Recycle for a better life.
