Castilla y Leon, and Castilla la Mancha. This part is also the most significant for industrial plants such as biomass crops and oilseed rape. In the southernmost regions of Castilla La Mancha and Catalunya, dry fruit trees and vineyards increase in significance, while the Ebro River delta supports a well-developed rice farming activity. Diffuse pollution originated by pesticides application in the basin has been widely studied [1-3]. A historical pollution from chemical plants manufacturing solvents and chlorinated pesticides in the southern part of the river basin is also well known [4]. Automobile, textile, food, and wood industry as well as mining activities are important in the northern part.

The rice husk-based bioelectricity hfe cycle starts with the production of agricultural inputs such as rice seed, fertihzer, and pesticide, which then are used for rice farming. After the rough rice grains are harvested, rice husk is separated from brown rice [44]. While the brown rice is normally processed to obtain white rice for commercial purpose, the rice husk is directly transported to the power plant for generating electricity. The operation of rice husk-based power plants is similar to that of coal-based power plants. Nevertheless, as rice husk tends to contain less sulfur than coal, limestone consumption is omitted when considering the rice residue-based power plant.
