Abstract Purpose of Review In this article, we review existing research addressing how environmental regulations have influenced the pulp and paper industry. These regulations appear in different forms and designs and address air and water pollution as well as climate change. The paper devotes particular attention to how various regulations have affected sustainable technological change and the prospects for inducing deep emission reductions without jeopardizing industrial competitiveness and future investments. Recent Findings Experiences from key pulp and paper regions, not least the Nordic countries, suggest that gradually tightening performance standards have contributed to radical reductions in emissions, e.g., chlorine compounds and biological oxygen demanding agents, and without imposing excessive compliance costs. This outcome can largely be attributed to how the regulations have been designed—and implemented—in practice, as well as to the presence of efficient and legitimate institutions. Long-term emission reduction targets, in combination with extended compliance periods and trustful firm-regulator relationships, contributed to radical technological innovation and permitted radical emission reductions without excessive compliance costs. The development of alternative bleaching technologies is an apt example. In contrast, the impact of carbon pricing schemes, including the EU emissions trading scheme, on carbon dioxide emissions reductions and related technological change in the pulp and paper industry has however been modest. Self-regulation, certification, and community pressure have exerted relatively modest influences on the environmental performance of the industry. Summary Important avenues for future research are identified. These include the following: (a) comparative research on how policy mixes in various countries have influenced environmental compliance and innovation; processes; (b) future studies of environmental regulations, their design and implementation, in emerging pulp and paper producing countries, not least China; and (c) research on how environmental regulations can affect ongoing restructurings in the industry towards a broader palette of products in biorefineries.

The article is devoted to the problem of increasing the efficiency of using energy resources of enterprises of the pulp and paper industry in Ukraine. It has been determined that the pulp and paper industry belongs to energy-intensive types of economic activity. Based on the results of the correlation and regression analysis, a connection was revealed and an economic and mathematical model was formed of the dependence of energy costs for the production of 1 ton of paper on the productivity of paper machines, equipment wear and the volume of investments in energy saving measures. Application of the proposed model will improve information support for the analysis of the effectiveness of energy saving measures, forecasting energy costs and strategic energy management in general. It was carried out at pulp and paper mills, the main obstacles to replacing fossil fuels with biomass in heat production were identified. This made it possible to develop a scientific and organizational model for the energy modernization of enterprises in the pulp and paper industry. It includes financial, organizational, environmental, regulatory, technological, scientific and educational tools. Their application at management will help improve the infrastructure of enterprises in terms of the use of renewable energy resources.

Agricultural residues and energy crops are promising resources that can be utilized in the pulp and paper industry. This study examines the potential of co-cooking nonwood materials with hardwoods as means to incorporate nonwood material into a paper furnish. Specifically, miscanthus, switchgrass, and corn stover were substituted for poplar hardwood chips in the amounts of 10 wt %, 20 wt %, and 30 wt %, and the blends were subjected to kraft pulping experiments. The pulps were then bleached with an OD(EP)D sequence and then refined and formed into handsheets to characterize their physical properties. Surprisingly, all three co-cooked pulps showed improved strength properties (up to 35%). Sugar measurement of the pulps by high-performance liquid chromatography suggested that the strength increase correlated with enriched xylan content.
