History
Discovery of Porto Santo: 1418, by João
Gonçalves Zarco and Tristão Vaz Teixeira.
The captain Bartolomeu Perestrelo, received letter
of donation in November of 1445.
The name of Porto Santo (Holy Port) comes from
the bay in the south coast.
The development of this place knew some
difficulties due to scarcity of water and to the
assaults of Algerian and French pirates.

Colombo House
Colombus married Perestrelos daughter and lived there for some time.
Columbus' house is a museum and permanent exhibition about life and family ties
Temporary art exhibitions.

Existing Solutions
All the collected municipal solid wastes are shipped to the incineration plant of Madeira.
The sludge from the local WWTP has high humidity, is putrescible and not suitable for incineration.
The green residues from gardens also have not a locally profitable use, being sent to incineration.
The island waste and sludge treatment and disposal are today under the responsibility of a single company.

ELECTRIC ENERGIA
the plant can satisfy about 1,2 % of electric energy demand of the Porto Santo island,or 3,5 % if energy crop are produced and used.
The biogas can be used in a cogeneration unit for the combined production of electric energy end heat with two motor-generators with 80-150 kW of electric power, connected in peak electric energy demand, in order to contribute to improvement of the island electric energy balance.
48
Heat uses
Will depend on the localization of the central biogas plant

houses,
Heating of swimming pools,

O PRODUTO DIGERIDO
Contém macro, micronutrientes e composto do carbono importantes para a formação do húmus.
Maior disponibilidade de Azoto para o crescimento das plantas.
Redução dos cheiros devido á menor concentração de compostos voláteis orgânicos.
Prevenção da queima das plantas devidas a menor concentração de ácidos.
Incremento da diversidade biológica do solo e melhoramento da qualidade das forragens.
Higienização por morte dos agentes infecciosos.
Supressão de fito patogénicos devido á libertação de antibióticos libertados por microrganismos.
Incremento da capacidade de retenção da água e nutrientes no solo
Maior homogeneização e facilidade de uso
Degradação de compostos infecciosos tais como os pesticidas.
57
ENVIRONMENTAL BENEFITS
Reduction of emission of CO2, NOx, SOx e CH4 to atmosphere due to substitution of fossil fuel by biogas, for the production of electric energy end heat.
Attenuation or elimination of smells
Improvement of the hygienic and sanitary conditions during residue handling and
Reductions of storage and of the number of trips between islands. .
58
ENVIRONMENTAL BENEFITS
Improvement of incineration plant burning performance.
Reduction of 360 ton/year of land filled cinder from biowaste.
Resolution of disposal of the sludge from the WWTP.
Promotion of an improved environmental figure of the Porto Santo Island.

income (€/year) energy Crop
Electric Energy 42 500 85 000

Fertilizers 20 000 -
Reduction of transportation and incineration costs
105 000 -
Total 181 000 112 000
60
ECONOMIC BENEFITS
The energetic crop can provide an additional annual income of 112 000 euro, to finance the cultivation of 50 ha of land area for energy crops production.
The necessary capital to invest is evaluated about 1 million of euro, but avoids investments in additional sludge treatment evaluated about 500 000 €.
The payback period evaluated in less than 5 years,
From a macroeconomic pointy of view, the Project will contribute to create added regional value and reduce the use of imported fossil fuels.
61
SOCIAL BENEFITS
Implementation of a sustainable system,
local wastes = renewable endogenous resource
Increases local employment, encourages the agricultural and territory defence practices.
Less pollution and more touristic actractivity
Promotes environmental conscience and awareness.
contributes to selective collection of Solid wastes
obtain carbon credits for green energy,
Is an opportunity to set-up a new and more profitable socio-environmental structure in the Porto Santo Island.
62
SWOT Analysis
SWOT analysis is applied to the non-technical barriers (NTB’s) regarding small scale future biogas investments in islands
The definition for NTB’s is : A non-technical barrier is a hindrance to a project, due to a human concern as opposed to a technical hindrance.
63
Analysis and deliberation to take advantage of factors that are considered as
strengths, to maintain them and build upon them,
to exploit and optimize factors that appear as opportunities,
to minimize the impacts of weaknesses, and
to protect against threats.
64
Results
We have identified a pick-list of 38 potential non-technical barriers.
We identified 26 barriers in Porto Santo, 25 barriers in Outer Hebrides, 19 barriers in Samos, 18 barriers in Samso, 16 barriers in Tremiti islands and 4 barriers in Sardinia.
5 barriers are common in five out of six islands. They are administrative, regulatory, economic and market related.
