The objective of this article is the conducting of an analysis of the production of selected energy plants that are already a basic source of agrobiomass in Poland. The analysis looks at environmental aspects and production conditions for biomass designated for energy for the Virginia mallow (Sida hermaphrodita), common osier (Salix viminalis), silver–grass (Miscanthus x giganteus), and switchgrass (Panicum virgatum). What is presented is an economic analysis of the production of selected energy plants, taking into account the costs of establishing plantations and their cost effectiveness. Moreover, logistic strategies for the delivery of biomass intended to secure continuous production of renewable energy as a part of sustainable development is signaled.

Many strains of microalgae are potentially useful for industrial purposes. Microalgal biomass and microalgae‐derived substances are becoming valuable products with a widening range of applications including biofuels and human food. In this study, the possibility of using the methane waste from biomass biodigestion in the cultivation of Chlorella vulgaris biomass with simultaneous waste treatment was investigated. The methane waste from biomass biodigestion was obtained from a multifunctional facility (Piaszczyna, Poland) producing bioethanol from plant biomass with several steps to reuse the wastes, heat, and carbon dioxide. The growth and biomass yield, as well as photosynthetic performance of C. vulgaris on diluted waste, were similar to the results obtained on the standard mineral medium. The cultivation of C. vulgaris was the waste, treatment step that significantly reduced chemical oxygen demand. The results indicated that the waste contained micro‐ and macronutrients sufficient to sustain the growth of C. vulgaris cell culture up to 2 g of dry biomass per liter of culture. The results contributed to the development of the waste treatment step in the Piaszczyna facility that allowed for a further decrease in emissions and may lead to development of microalgae biomass‐based products in the facility portfolio.

The objective of this article is a presentation of priority questions and relations involving economic and soil conditions for the application of phytoremediation technology in restoring sustainable development to the environment. The analysis looks at the justifiability of the application of phytoremediation in restoring a balanced environment as an alternative method to costly land recultivation aimed at eliminating pollutants—a solution that is impossible in the case of large areas. The cost effectiveness of the use of phytoremediation in the recovery of trace element in the soil through the process of phytoremediation was demonstrated. The quality of soils as found in the Voivodeship of Łódź was analyzed from the point of view of potential application of the phytoremediation method, taking into account subdivision by heavy metals found in the soils as well as their origins and properties. Grades of soil purity are presented and border values of heavy metal content were identified.  

In the context of achieving the targets of the energy economy, Poland’s demand for bioenergy is stimulated by several factors, including the biomass potential of agricultural cultivation. The objective of this article is to indicate perspectives for the sustainable production of energy crops in Poland through the production of total biomass as the main renewable source of energy utilized in the countries of Europe and supported by Directive 2009/28/EC of the European Parliament and of the Council of April 23, 2009 on the Promotion of the Use of Energy from Renewable Sources, currently in force. The most important reasons for promoting the production of plant biomass for energy purposes is the desire to work against climate change and reduce the emission of greenhouse gasses. This article indicates the significant role of Life Cycle Assessment (LCA) in biofuels and their production. Note is also taken of agro– climatic and soil conditions for the production of biomass in Poland as well as the economic aspects using the Agricultural Production Space Valuation Ratio (APSVR).

The goal of this article is a presentation of the legal, biological, and economic conditions of energy production using biomass, especially taking into account the application of sewage sludge certified for natural use in agriculture. Any increase in the production of biomass necessitates the introduction of cheap and highly-efficient plant production technologies that are environmentallyfriendly. Use of certified sewage sludge can increase the economic efficiency of energy crops and have a beneficial impact on the environment.
