Rapid economic development is accompanied by an increase in energy demand. The reason for this was the impending fuel energy crisis and the ever-increasing pollution of the environment. Pellets, a type of biofuel widely used in developed countries, have become an alternative source of thermal energy. In Russia, they are mainly produced in the central regions, but are used to a limited extent. This study examines the growing global demand for sustainable energy, with a particular focus on wood pellets. The goal is to assess the environmental and economic benefits of pellets, their feasibility and practical application. The work compares pellets with other types of fuel, emphasizing their environmental benefits: reduced emissions, efficient waste disposal, and contribution to energy sustainability.

The global diamond industry is experiencing a profound structural crisis and radical transformation caused by the rapid growth of the synthetic diamond market. The main battle is between natural diamonds, whose value is based on their rarity and geological history, and lab-grown diamonds, which, while physically identical, are offered at 70–90% less. This advantage of the latter is "two-sided": their price is rapidly declining due to technological advances, while natural stones retain their value. The crisis is exacerbated by fierce competition, structural weaknesses in the industry, and supply chain losses. Key dividing points have become issues of sustainability, ethics, and legal regulation, requiring clear labeling of synthetics. As a result, the market is fragmented: natural diamonds are gaining ground in the luxury segment, while lab-grown diamonds dominate accessible luxury and fashion. The future is seen in the coexistence of both products based on clear consumer choice and transparency.
