“…It is noteworthy that apart from the beneficial environmental impact of an SRC plantation and the yield, the biomass quality is also very important as it has an impact on the effectiveness of its use and emissions produced in various bioenergy technologies. Woody biomass, including willow and poplar, is successfully used as an energy feedstock in the combustion of chips, pellet and briquette [20][21][22][23]. Increasing attention has been attracted recently by the cascade use of lignocellulosic biomass.…”

Willow biomass is used as a bioenergy source in various conversion technologies. It is noteworthy that apart from the beneficial environmental impact of a willow plantation, the biomass quality is also very important as it has an impact on the effectiveness of its use and emissions produced in various bioenergy technologies. Therefore, this study analysed the thermophysical properties and elemental composition of 15 genotypes of willow biomass from two plantations situated in the north of Poland, harvested in two consecutive three-year rotations. The differences in the moisture content, ash content and the lower heating value were mainly determined by the genotype, i.e., by genetic factors. In contrast, the content of carbon, nitrogen, sulphur and hydrogen was determined by the location (environmental factors), but also by the genotype, and by a combination of these factors. The following were the mean levels of the willow biomass characteristics, regardless of the location, genotype and harvest rotation: 48.9% moisture content, 1.26% d.m. ash content, 19.4% d.m. fixed carbon, 79.4% d.m. volatile matter, 19.53 MJ kg−1 d.m. higher heating value, 8.20 MJ kg−1 lower heating value, 52.90% d.m. carbon, 6.23% d.m. hydrogen, 0.032% d.m. sulphur, 0.42% d.m. nitrogen. The present research has shown that the selection of the willow genotype is important for the quality of biomass as energy feedstock. However, plantation location, as well as successive harvest rotations, can have a significant impact on the biomass elemental composition.

“…It was also assumed that 5% of pastures are not fully used (excluding fallows) and one cut of hay can be obtained annually as energy feedstock. The annual average energy potential of hay from pastures was taken as 50 GJ ha −1 year −1 [68,74] and it was included in the Equation (12). Late cut biomass from pastures can be used, which is beneficial as late swath is more flexible than early because of the weather conditions.…”

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.

“…Enerji tüketim miktarı dünya nüfusunun çoğalması ve sanayideki teknolojik gelişmelere bağlı olarak artırmaktadır. Enerji arzının büyük bir kısmı fosil kökenli kömür, doğal gaz, motorin gibi kaynaklardan sağlandığından oluşan sera gazı etkisi çevresel problemlere sebep olmaktadır (Kalinichenko & Havrysh, 2019;Sharma et al, 2020;Stolarski et al, 2020). Buna bağlı olarak atmosferdeki fosil kaynaklı karbondioksit artışı 1900 yılında yaklaşık 280 ppm iken günümüzde 409 ppm olarak belirlenmektedir (Lindsey, 2021).…”

ÖzDünya nüfusunun artışı ve teknolojik gelişimler sebebiyle ortaya çıkan gıda ve enerji talebini karşılayabilmek için araştırmalar yoğun şekilde devam etmektedir. Enerji ihtiyacını giderebilmek için arz doğal gaz, kömür, petrol gibi fosil kaynaklı yakıtlardan ya da nükleer kaynaklardan sağlanmaktadır. Fosil kaynakların miktarının sınırlı olması ve oluşturduğu sera gazı etkisi sebebiyle alternatif enerji araştırmaların birçoğu biyodizel, biyogaz, rüzgâr, güneş enerjisi gibi yenilenebilir yakıtlar üzerinde yoğunlaşmıştır. Sera gazı etkisini oluşturan gazlar içerisinde karbondioksit ile birlikte metanojen bakterileri tarafından üretilen metan(bataklık-biyogaz) gazları önemli bir yer tutmaktadır. Uygulanabilirliği, sürdürülebilirliği, düşük üretim maliyeti, sera gazı oluşumunu azaltması ve süreç sonucu elde edilen biyokütlenin organik gübre olarak kullanılabilmesinden dolayı biyogaz üretimi alternatif yakıtlar içerisinde ön plana çıkmaktadır. Bu amaçla, birçok ülkede biyogaz üretimi ve buna bağlı oluşan biyogübrenin tarımda kullanımı artarak devam ederken ülkemizin bu alandaki potansiyelinin yeterince belirlenemediği görülmektedir. Yapılan bu çalışmada ülkemizin bir ilçesi model olarak incelenerek toplam biyokütle potansiyeli belirlenmiş ve biyokütle potansiyeline bağlı olarak elde edilebilecek biyoenerji miktarı araştırılmıştır. Elde edilen sonuçlar incelendiğinde, model ilçenin biyokütle potansiyelinin ilçenin enerji ihtiyacının üzerinde olduğu ve biyogaz üretimi sonrası oluşacak biyogübrenin kullanımı ile toprak kirliliğine sebep olan inorganik gübre kullanımının azaltılabileceği görülmüştür.
