Effects of field’s topology on energetic efficiency of rapeseed plantation for biofuel production

Wasiak A., Orynycz O.

Applied Computer Science

2015

Vol. 11, no 1

83--98

The model, developed earlier, have been designed to the studies of energy gain in the biofuels production, as compared to the sum of energy inputs on various production steps, and in processes enabling biomass conversion to energy. The present paper shows application of that model towards estimation of the contribution of energy used for commuting between agricultural production sites for a chosen example of plantation’s topological characteristics. Algorithm for computations is elaborated, and numerical example is shown. The sizes of the fields as well as distances between them determine the amount of energy spend for the agricultural work in addition to the tillage technologies being applied.

Effects of tillage technology on energetic efficiency of rapeseed plantation for biofuel production

Orynycz O., Wasiak A.

Vol. 10, no 2

67--76

Biofuel production, as well as any other production processes, involves a number of conversion steps each of those is connected with unavoidable consumption of energy. Since biofuels are intended to replace fossil fuels it is important that the sum of energy inputs into subsequent technological steps does not exceed the energy output from the system. Basing on theoretical model derived recently by present authors, energy require-ments for several agricultural technologies are computed, and used for estimation of energetic efficiency of rapeseed plantations dedicated for biodiesel fuel production. The effects of technological choices on energetic efficiency of plantations are demonstrated basing on numerical compu-tations performed using realistic data.
