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.

In the Republic of Serbia, sour cherries are grown on approximately 14,000 hectares and represent the fourth fruit species in terms of area. The pits that remain after the processing of sour cherries are a by-product that burdens the business of the processors of this fruit. The quantities of pits that are produced annually are estimated at around 7,000 tons. This represents a good energy potential, bearing in mind that the calorific value of sour cherry pits is around 22 MJ / kg of dry matter. An additional convenience of sour cherry pits is in their dimensions that make them suitable for direct use in pellet boilers, without any pre-treatment. One of the boilers in which it is possible to burn dried sour cherry pits in order to obtain thermal energy, is Šukoplam VENT, a manufacturer of boilers Šukom from Knjaževac. This boiler has good characteristics such as: high efficiency (up to 94%), quality of materials and workmanship, the possibility of using several types of biofuels and their quality combustion, based on which it met the requirements for Class 5 (Ecodesing) related to pollutant emissions by the latest European standards.

AbstractThis article deals with energetic evaluation and potential of pomace – a waste product originating during production of grape wine. Calorimetric analysis of 19 grapevine varieties was performed in 2013 and 2014. The aim was to specify their combustible limit and the gross calorific value. The evaluations were performed on pristine pomace, pomace without seeds, and only on seeds themselves. The results obtained imply that pomace is an interesting energetic resource with a gross calorific value of 16.07-18.97 MJ kg−1. Lower calorific values were detected in pomace after seed separationie14.60-17.75 MJ kg−1; on the contrary, seeds alone had the highest calorific values of 19.78-21.13 MJ kg−1. It can be assumed from the results of energetic evaluation of pomace in Czech Republic conditions that, by purposeful and efficient usage of pomace, 6.4 GWh of electric energy and 28 GWh of thermal energy can be generated.

Bamboo is a versatile, rapidly growing renewable raw material with high productivity, low handling cost, high ability to sequester atmospheric carbon and potential for energy purposes. The paper aimed to describe the potential of bamboo for energy purposes through different product alternatives. A specific literature review was carried out to tabulate data related to different energy alternatives for bamboo, considering the following questions: (i) which are the alternative bamboo products with energy potential? (ii) what are the parameters traditionally described in scientific articles? The average value of 4,396, 6,994, 4,597 and 4,530 kcal.kg-1, was found in the Gross Calorific Value (GCV) of biomass, charcoal, briquette and pellets of different bamboo species, values similar to those found for Eucalyptus grandis x Eucalyptus urophylla hybrid wood. The data prove the potential of bamboo as a source of energy and may even replace tree species traditionally used.

The use of waste for energy production through processes like pyrolysis, combustion and oil extraction is a sustainable solution to serious environmental problems like centralization of the energy matrix in nonrenewable materials and pollutants and the volume of urban solid waste. In this context, this work aimed to analyze the energy potential of two solid waste biomasses: municipal slaughter sludge and wood sawdust generated in the city of Gurupi –TO. Were evaluated the contents of humidity, volatile content, ash, fixed carbon through the immediate analysis and upper (PCS) and lower (PCI) calorific value were evaluated for all samples collected. In the immediate analysis it was found that the sludge sample had higher ash content than the sawdust and both had high volatile contents. The sawdust presented higher calorific power (4882 cal kg-1) than the sludge (3952.5 cal kg-1), but the process of obtaining energy from the sludge requires less heat. It can also be concluded that both materials present viable alternatives for obtaining energy.

This paper targets the future energy sustainability and aims to estimate the potential energy production from installing photovoltaic (PV) systems on the rooftop of apartment’s residential buildings, which represent the largest building sector. Analysis of the residential building typologies was carried out to select the most used residential building types in terms of building roof area, number of floors, and the number of apartments on each floor. A computer simulation tool has been used to calculate the electricity production for each building type, for three different tilt angles to estimate the electricity production. Tilt angle, spacing between the arrays, the building shape, shading from PV arrays, and other roof elements were analyzed for optimum and maximum electricity production. The electricity production for each household has been compared to typical household electricity consumption and its future consumption in 2030. The results show that installing PV systems on residential buildings can speed the transition to renewable energy and energy sustainability. The electricity production for building types with 2–4 residential units can surplus their estimated future consumption. Building types with 4–8 residential units can produce their electricity consumption in 2030. Building types of 12–24 residential units can produce more than half of their 2030 future consumption.

Recovery Potential

The use of micro-hydropower (MHP) for energy recovery in water distribution networks is becoming increasingly widespread. The incorporation of this technology, which offers low-cost solutions, allows for the reduction of greenhouse gas emissions linked to energy consumption. In this work, the MHP energy recovery potential in Spain from all available wastewater discharges, both municipal and private industrial, was assessed, based on discharge licenses. From a total of 16,778 licenses, less than 1% of the sites presented an MHP potential higher than 2 kW, with a total power potential between 3.31 and 3.54 MW. This total was distributed between industry, fish farms and municipal wastewater treatment plants following the proportion 51–54%, 14–13% and 35–33%, respectively. The total energy production estimated reached 29 GWh∙year−1, from which 80% corresponded to sites with power potential over 15 kW. Energy-related industries, not included in previous investigations, amounted to 45% of the total energy potential for Spain, a finding which could greatly influence MHP potential estimates across the world. The estimated energy production represented a potential CO2 emission savings of around 11 thousand tonnes, with a corresponding reduction between M€ 2.11 and M€ 4.24 in the total energy consumption in the country.
