Decision analysis for the determination of biomass in the territory Tuscia Romana by geographic information system and forest management plans

Abstract

The growing interest in the development of chains for the use of agroforestry biomass for energy demand, is due to the awareness they are a crucial element to mitigate the global climatic change effects. The true effort is to have a reliable estimation of biomass availability by some instruments like forest management plans, which allow to locate the forest supply and to know the forest biomass availability in a medium period. In this paper we carried out a decision analysis by geographic information system, in Tuscia Romana area comprising 11 municipalities for a total amount of 813 km 2 . An estimation was carried out taking into account the bibliographic data on the analyzed species, reporting the biomass in weight taken out by the forest cut utilization. A comparison was also performed in field on chestnut trees cut in a sampling area near Bracciano and in a close sawmill. The results show long, medium and short-term dynamics, but some critical points were found related to the process of estimation and to the real procurement of biomass in some years. The results suggest to be care in a possible project of a biomass plant.

Preparation of Lignin Nanoparticles with Entrapped Essential Oil as a Bio-Based Biocide Delivery System

“…The BDSs prepared in the actual work, characterized by a strongly delayed release of the entrapped biocides, present a promising way to reduce the amounts of EOs used for biocontrol applications and thus increasing their cost-effectiveness. Through the use of wood-processing side streams for lignin isolation and preparation of nontoxic and biodegradable LNPs, costs of future products can additionally be reduced as well as environmental impacts of otherwise for energy generation used residual biomass from wood processing. − The availability of considerable amounts of residual biomass offers chances for innovations and the implementation of new value chains in the wood sector, especially in areas where sawmills suffer from economic pressure to generate revenue using side and waste streams. − …”

Land use planning for utilizing biomass residues in Tuscia Romana (central Italy): Preliminary results of a multi criteria analysis to create an agro-energy district

“…This is because the CLC data was not very detailed. For each municipality we have considered total resource (m 3 ); we have calculated the biomass available for energy use (m 3 ) as 18% of the total resource, in accordance with the method reported by Hellrigl (Hellrigl, 2004;Kinoshita et al 2009;Colantoni et al, 2013;Sacchelliet al, 2013;Colantoni et al, 2015). Finally, using the net calorific value (assuming a water content of 33%) we have obtained the energy availability in terms of kWh th (Tab.…”

Estimation of agroforestry biomasses available for energy purposes in a municipality in central Italy as instrument for energy planning

“…The parameters used to evaluate the forest biomass potential are extracted from the study conducted for the Tuscia -Romana area [3], data is listed in tables 3.…”

“…The biomass for energy use is calculated by: Table 3: amount of biomass for forest species and type of government, with relative water content (IC) and moisture (U) [3]; in relation to forest biomass, are reported the mass as a function of volumetric water content (IC); the amount of biomass (18 % of total biomass) allocable to energy use; the calorific value (Cv); the lower calorific value (Lcv); the total energy content [3].…”
