#### 3.3.3 Results Economic-Financial Analysis (80% Olive and 20% Plastic)  
Finally, the results for the fuel mixture of 80% olive biomass and 20% plastic applying formulas, the results obtained are presented in Table 14.  
Therefore, it obtains the electrical energy produced for one hour (7.90 kWh/h), totaling the total annual energy produced at 28.430.53 kWh/year and the income from annual energy sales, according to which, the expected annual operating hours it will be 5686.11 \(\upxi\)/year.  
With this power, one will have to install a 10-KW gasifier, so the necessary investment (K) according to Table 10 will amount to EUR 12,000.00 (applying a 23% VAT in Portugal); the total investment would be 14,760.00 euros. On the other hand, this type of clean energy production equipment in Portugal is subsidized with POSEUR Aid by 65%, which means, for an economic study with 10 years of useful life, a subsidy of 780.00 \(\upxi\)/year. In addition, it will avoid having to send plastic WEEE waste to the landfill with a saving of 181.44 \(\upxi\)/year according to Tables 9 and 14.  
On the other hand, it will have operating expenses of around 5% of investment costs (600 \(\upxi\)/year), along with personal costs, which amounts to 3150 \(\upxi\)/year, in addition to the purchase costs of olive biomass that rise to 432.00 \(\upxi\)/year. The results are shown in Table 15.
