Biomass Resources

An area of the Odessa oblast includes 26 administrative districts with developed agricultural traditions. The productivity of main grain crops in the Odessa oblast comprises several million tons every year. Annually, the vegetable residues in the Odessa oblast upon harvesting make a significant amount. Biomass includes both nutritional and energy potential, which requires new approach in the storage and treatment. At the same time, the current problems with high cost of the traditional energy sources create various obstacles in the fields of agricultural activity. Recently, considerable attention is focused on the process of  biological conversion of the biomass to methane. Rising segment of biomass application in the energy strategies all over the world implies the need for greater accumulation of biomass resources to meet the demand. The purpose of this publication is an assessment of vegetable biomass amount in the districts of the Odessa oblast, potential of nutrients and biogas energy generated from the biomass. The analysis corresponds to the search of new alternative energy resources and the rational use of organic biomass. The agricultural biomass residues are the resource category with relatively high regeneration capacity. This property can be used for producing nutrient-rich organic fertilizers and high-energy biogas to compensate the traditional fossil fuel dependence. The availability of agricultural biomass resources was found to demonstrate the great perspectives for the bioenergy sector, first of all in view of the adopted waste management strategies.

Biomass For Energy

This research analyzed the degree of utilization of the agricultural biomass for energy purposes (combustion), in order to indicate the reasons that limit its use. The biomass potential was studied by means of the methodology of the biomass potential, whereas the factors suggesting a low degree of biomass utilization were identified by means of factor analysis. The research results reveal that there is an enormous potential of the unused agricultural biomass. This dissertation research significantly contributes to the establishment of a genuine mathematical model based on multiple linear regression. The solution obtained by this analysis, in both a mathematical and a scientific manner, conveys the primary reasons for an insufficient utilization of the biomass for energy purposes. Moreover, the paper suggests the measures to be applied for a more substantial use of this renewable source of energy and presents the expected benefits to be gained.

In this work the amount of biomass available by the hazelnuts pruning in the province of Viterbo was investigated. At present, the pruning’s residues are destroyed by farmers directly in the field, at the end of the pruning; in this way a large quantity of biomass, represented by hazelnut’s prunings, is lost; the residues obtained from the hazelnut’s pruning, are an important source of biomass that could be used for thermal energy production. The aim of this work is to realize a map with the estimated energy potential from hazelnut pruning biomass, in the province of Viterbo. In the first phase the amount of biomass obtained from a hectare of hazelnut’s cultivationwas estimated:sampling were carried out in some municipalities of Viterbo while hazelnut pruning was taking place, from January to March.In the field, biomass was weighed and some pieces of wood were collected for laboratory analysis; in particular humidity of biomass, low calorific value, ashand the content of carbon (C), hydrogen (H) and nitrogen (N) were determined. In the calculation of the biomass were considered the age of the plants and the number of plants per hectare. The results show that the amount of biomass obtained from pruning of hazelnuts varies with the age of plants, but even more so by the number of plants per hectare. The average value of biomass obtained from pruning of a hectare of land is just under 0,9 t. Knowing the net calorific value of the hazelnut wood and the number of hectares cultivated for each municipality, a map of thermal potential energy has been realized.

Biogas is a promising source for energy production in future energy systems. In this paper, the energy flows in the life cycle of a real biogas plant (Mirotin-Vrbas) for thermal energy production were considered, starting from corn silage production, cow manure transport, process of anaerobic digestion and biogas production, to the use of solid and liquid digestate for production of crops. Four energy indicators were used to evaluate energy flows in this work. The obtained results showed that this biogas system has a positive energy balance of 62.418 GJ and an energy efficiency of 6,1, which indicates that in terms of substitution of fossil fuel consumption, this system for heat production is a good alternative.

My research work proposes the study of the impact of the biogas production by co-fermentation of agricultural products. The basic substance is the dangerous liquid pig manure of the concentrated stock of big pig farms. The utilization of these materials as an energy source spells large income for the agricultural enterprises, saving the replacement of plant nutrition utilization of bio-manure, to increase the performance of the plant production, making harmless the dung which means a big environmental load. Because of the profitability of bioenergy utilization depends on the local conditions it is necessary to do experiments to try the available composition of organic wastes in the ratio of the production in advance. We measured the quantity and the methane and CO2 content of the biogas released from the substrate. The experiment simulated real biogas plant conditions, in mesophile temperature, in continuous biodegradation process. It can be considered, as a semi-industrial size.

The objective of the current work is the investigation of the current utilization of olive tree residues, by-products and waste for energy generation in Crete and their future prospects. The quantity of olive tree biomass in Crete has been estimated and its potential for energy generation has been calculated. Possibilities for using it for heat production, power generation, biogas production, pellet manufacturing and fermentable sugar production have been investigated. Experiences in other olive oil producing countries have been recorded together with the technologies used or experimented with so far. The energy potential of olive tree biomass in Crete has been estimated at 24.05 % of the TPES supply in the island. The only highly utilized olive tree by-product for heat generation by combustion in Crete is the olive kernel wood. Olive tree pruning have the highest energy content but they are underutilized in Crete. Their successful utilization in other countries for pellet manufacturing and power generation indicates that their exploitation should be promoted in Crete. The results of this study indicate that olive tree cultivation in Crete, apart from producing a high nutritional edible product, generates residues, by-products and waste which if properly utilized could contribute in the reduction of fossil fuels used and the carbon footprint due to energy use in the island.
