#### 3.3.2 Results Economic-Financial Analysis (90% Olive and 10% Plastic)  
For a mixture introduced into the gasifier consisting of 90% olive biomass and 10% plastic applying Formulas (6), (8)-(10), the results are presented in Table 12.  
Therefore, based on Formula (9), it will obtain the electrical energy produced for one hour (10.79 kWh/h), and the total annual energy produced at 38,835.08 kWh/year. We expected annual energy sales, of 7767.02 \(\epsilon\)/year.  
With this power, we will have to install a 15-KW gasifier, so the necessary investment (K) according to Table 10 will amount to EUR 18,000.00 (applying a VAT of 23% in Portugal) the total investment would be EUR 22,140.00. 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 1170.00 \(\epsilon\)/year. In addition, it will avoid having to send plastic WEEE waste to the landfill with a saving of 125.19 \(\epsilon\)/year according to Tables 10 and 13.

On the other hand, it will have operating expenses of around 5% of investment costs (900 \(\upxi\)/year), along with personal costs, which amounts to 3150 \(\upxi\)/year, in addition to the purchase costs of olive biomass that rise to 670.68 \(\upxi\)/year. The results are shown in Table 13.
