“…After calculating of the abovementioned single costs, the total cost of seagrass-based boards is estimated at 66.4 EUR m −3 , while the cost of WF-based boards reaches 95.1 EUR m −3 ( Figure 6 ). The obtained costs are within the range of estimated costs (37–145 EUR m −3 , excluding the logistics) for wood-based insulation materials, mentioned in previous work [ 42 ].…”

Seagrass wracks, the remains of dead leaves accumulated on seashores, are important ecosystems and beneficial for the marine environment. Their presence on the touristic beaches, however, is a problem for the tourism industry due to the lack of aesthetics and safety reasons. At the present time, seagrass leaves are landfilled, although this is not considered an ecological waste management practice. Among other proposed practices for more sustainable and environmentally friendly management, such as composting and biogas or energy generation, in this study we aim to use seagrass leaves for the production of insulation materials. Insulation boards from two types of seagrass leaves (Posidonia oceanica and Zostera marina) at densities varying from 80 to 200 kg m−3 were prepared and their physical and mechanical properties were examined and compared to those of wood fiber insulation boards. The thermal conductivity of seagrass-based insulation boards varied from 0.042 to 0.050 W m−1 K−1, which was up to 12% lower compared to the latter. The cone calorimetry analysis revealed that seagrass-based insulation boards are more fire resistant than those from wood fibers, as they release very low amounts of heat during combustion and do not ignite when exposed to a single flame (Bunsen burner). A simplified cost analysis showed that insulation boards made from seagrass leaves can be up to 30% cheaper compared to those made from wood fibers. After their end of life, seagrass leaves can again be considered a valuable resource and be further utilized by adopting other management strategies.

“…The economic analysis was carried out considering a target density of the insulation board of 200 kg m −3 . For this analysis, we referred to the data of a previous study, conducted by Rocchi et al [ 42 ]. The authors studied the use of pruning remains from Tilia wood to produce insulation boards.…”

“…The approach to environmental problems through life-cycle analysis, which we can define as "Life Cycle Thinking", originated around the end of the 1960s, when the problems related to excessive resources consumption was already beginning to be perceived [ 22]. The LCA methodology proposes a systemic view of production processes, through an objective assessment and quantification of energy and environmental loads and of the potential impacts associated with a product/process/activity [23], along the entire life cycle, from the acquisition of raw materials to the final disposal (so called "from cradle to grave " approach).…”

The present work aims to analyse the environmental advantages of a production process that applies circular economy. The study examines a product that is generated through the use of a certain percentage of recovered secondary materials, thus helping to avoid impacts related to the disposal of these materials and preserving the ecosystems from indiscriminate excessive natural resources extraction. The product analysed is an ecological detergent (“Ri-Detersivo” – Re-Detergent), produced by the company Tea Natura, mainly composed of regenerated vegetable oils coming from food industry. The methodology used in this paper is Life Cycle Assessment (LCA). A partial LCA will be carried out here, arriving at the saponification phase, and comparing the environmental impacts deriving from the Re-Detergent production process with those of a traditional soap, comparable to that studied in terms of function. The analysis of the case study found that the use of regenerated vegetable oils for the production of soap allows to significantly reduce the environmental impacts compared to the use of coconut oil imported from third countries.

“…About 14 Mg of wood biomass, with an energy potential of 113 GJ y −1 , can be obtained from the roadsides in the commune (Table 4). The presence of trees on roadsides ensures that biomass can be acquired by pruning, which is usually wasted [104]. The potential in this regard also increases as the process may contribute to roadside naturalization when the biomass of an invasive species is obtained, which can be replaced by native flora, thereby improving biodiversity [105].…”

Solid Biomass Energy Potential as a Development Opportunity for Rural Communities

Conventional energy sources often do not fully satisfy the needs of a modern economy, especially given the climate changes associated with them. These issues should be addressed by diversification of energy generation, including the development of renewable energy sources (RES). Solid biomass will play a major part in the process in Poland. The function of rural areas, along with a well-developed agricultural and forest economy sector, will be a key aspect in this as these areas are suitable for solid biomass acquisition in various ways. This study aimed to determine the solid biomass energy potential in the commune of Goworowo to illustrate the potential in the smallest administrative units of Poland. This research determined the environmental and natural conditions in the commune, which helped to identify the crucial usable solid biomass resources. The total energy potential of solid biomass resources in the commune of Goworowo amounted to 97,672 GJ y−1. The highest potential was accumulated in straw surplus (37,288 GJ y−1) and the lowest was in wood from roadside maintenance (113 GJ y−1). This study showed that rural areas could soon play a significant role in obtaining solid biomass, and individual communes could become spaces for the diversification of energy feedstock.
