The aim of the work is to carry out a feasibility study of projects for the production of solid biofuels from biomass of pruning of perennial agricultural plantations for further use in boilers. Currently, this bioenergy sector is at the beginning of its development in the EU and in Ukraine, however it has quite good prospects for the future. An assessment of the energy potential of biomass obtained from pruning and removal of orchards and vineyards in Ukraine is performed. According to data of 2019, this potential is estimated at 116.2 ktoe. Though this potential is only a minor part of the total energy potential of biomass in Ukraine (23.6 Mtoe in 2019), biomass of these types is an important local fuel for the regions of its generation and can significantly reduce their dependence on traditional energy carriers. Biomass of pruning and removal of agricultural plantations can be a feedstock for chips (more often for hog fuel) or for solid biofuels of higher quality such as pellets and briquettes. Fuel properties of such solid biofuels are slightly worse than those of biofuels from forest wood or energy crops, but still high enough for the effective use in energy equipment. The main features are higher ash content and, accordingly, lower calorific value. The feasibility study of a typical project for the production of briquettes from vineyard pruning demonstrated economic viability of such projects in Ukraine. Further research in this area will lie in the feasibility study of obtaining solid biofuels from biomass of pruning and removal of orchards, as well as projects for the production of heat from such biofuels for Ukraine’s conditions.

Muskoxen (Ovibos moschatus) have been farmed since the 1960s for their fiber, called qiviut, a luxurious and highly valued underwool that is their primary insulation during the Arctic winter. Muskoxen are uniquely adapted to the Arctic. They thrive on local forages, do not require protection from the cold, and adapt well to many traditional husbandry practices. While muskoxen can be farmed for qiviut, the question remains whether it is an economically feasible and potentially sustainable enterprise in subarctic Alaska. This feasibility study was conducted using an enterprise budget for two herd sizes, 36 and 72 muskoxen, to estimate the principal costs and model different sales combinations. Under several revenue-generating scenarios, the feasibility study indicated a potential for economic viability of an established enterprise. The most profitable scenario for either herd size was selling all the qiviut as value-added yarn, coupled with livestock sales. In the absence of selling livestock, the enterprise was profitable at either scale assuming all the qiviut was sold as yarn. Selling qiviut solely as raw fiber was not projected to break even under the model parameters. The modeled enterprise emphasized the importance of value-added goods, economies of scale, low or zero opportunity costs, and the potential of a more active livestock market.
