“…Essa crescente produção de papel aumenta a demanda por fontes de energia, levando a maiores emissões de gases que causam o efeito estufa [57,58] . Para reduzir esse impacto, especialmente na produção de papel para jornal, a medida mais eficiente tem sido a substituição de celulose termo-mecânica (TMP) pela pasta reciclada, a qual o processamento consome menos energia elétrica [58,59] . A produção de papel a partir de fibras recicladas, além de consumir menos energia, economiza recursos naturais e diminui a poluição ambiental [60] .…”

AesumoA mudança de hábito e o aumento do consumismo nas últimas décadas levaram a inovações tecnológicas e consequentemente à maior produção de bens de consumo, o que gerou um aumento na produção de embalagens. As embalagens estão presentes em diversos setores, dentre eles destacam-se as indústrias de alimentos, nas quais as embalagens têm como principal função contribuir para conservação do alimento, além de vender o produto. Diferentes materiais são utilizados na fabricação de embalagens para alimentos, sendo eles os plásticos, metais, vidro e celulose. Cada material possui suas diferentes características para conservar o produto, dentre elas as principais são propriedade de barreira a gases, aroma, luz, água, microrganismos e resistência mecânica. No entanto, apesar das diversas vantagens de sua utilização, seu uso e descarte desordenado gera um grande volume de resíduos sólidos, que estão associados ao impacto ambiental. Em preocupação a essa situação têm-se buscado meios alternativos para reduzir tais impactos podendo destacar a reutilização e reciclagem das embalagens, bem como o desenvolvimento de polímeros verdes e materiais biodegradáveis. Palavras-chaves: meio ambiente, biodegradáveis, reciclagem, resíduos sólidos. AbstractChange of habits and increasing consumerism observed in the recent decades have widely influenced technological innovations, as well as the growth of consumer goods production, which has consequently required a crescent packaging production. Packages are used in diverse sectors, among them the food industry stand out, in which their main functions are to contribute to food conservation and selling the product. Different materials, such as plastics, metals, glass and paper, have been used in the food packaging production. Each material has different attributes that help to conserve the product: gas, aroma, light, water barrier, microorganisms and mechanical strength are the main ones. Despite the several advantages of its application, its uncontrolled use and disposal result in a large volume of solid residues and environmental impact. Concerning this situation, alternative practices, such as reuse and development of biodegradable and green polymers, have been considered in order to reduce the impacts.

“…Life cycle assessment (LCA) is a useful method for the comprehensive and quantitative assessment of a variety of environmental impacts, and this method is widely used for resources, products, and services. Several researchers have conducted LCAs of individual wood products and their applications, while focusing on issues such as energy (Bright and Strømman 2009;Wolf et al 2016;Røyne et al 2017), building construction (Jönsson et al 1997;Börjesson and Gustavsson 2000), furniture (Iritani et al 2015;Wenker et al 2017), paper (Ghose and Carrasco 2013;Achachlouei and Moberg 2015), and waste wood (Morris 2017). To obtain a broad understanding of the role of wood use in relationship to various environmental issues, it is important to examine wood-related usages from the viewpoint of large spatial and temporal scales.…”

Summary In this study, we used material flow analysis and life cycle assessment to quantify the environmental impacts and impact reductions related to wood consumption in Japan from 1970 to 2013. We then conducted future projections of the impacts and reductions until 2050 based on multiple future scenarios of domestic forestry, wood, and energy use. An impact assessment method involving characterization, damage assessment, and integration with a monetary unit was used, and the results were expressed in Japanese yen (JPY). We found that environmental impacts from paper consumption, such as climate change and urban air pollution, were significant and accounted for 56% to 83% of the total environmental impacts between 1970 and 2013. Therefore, reductions of greenhouse gas, nitrogen oxide, and sulfur oxide emissions from paper production would be an effective measure to reduce the overall environmental impacts. An increase in wood use for building construction, civil engineering, furniture materials, and energy production could lead to reductions of environmental impacts (via carbon storage, material substitution, and fuel substitution) amounting to 357 billion JPY in 2050, which is equivalent to 168% of the 2013 levels. Particularly, substitution of nonwooden materials, such as cement, concrete, and steel, with wood products in building construction could significantly contribute to impact reductions. Although an increase of wood consumption could reduce environmental impacts, such as climate change, resource consumption, and urban air pollution, increased wood consumption would also be associated with land‐use impacts. Therefore, minimizing land transformations from forest to barren land will be important.

“…Many previous studies have conducted LCA targeting of the GHG balances of individual wood products and applications, including buildings [3][4][5], furniture [6,7], paper [8,9], energy [10][11][12][13][14], and civil engineering [15][16][17]. In addition, several LCA studies have covered multiple or whole wood applications [18][19][20][21].…”

Throughout its life-cycle, wood contributes to climate change mitigation through carbon storage and material and energy substitution. Focusing on wood use for piles, check dams, paved walkways, guardrails, and noise barriers, we quantified the nationwide potential for climate change mitigation in civil engineering in Japan through 2050. To assess mitigation potential, we examined life-cycle greenhouse gas (GHG) emissions that are avoided by storing carbon in wood and forests, substituting wooden materials for non-wooden materials (cement, concrete, steel, and asphalt), and substituting processing residue and waste wood salvaged from defunct civil engineering structures for fossil fuels (heavy oil). Our projections suggest that there will be a maximum potential domestic log volume of 6.80 million m 3 /year available for civil engineering use in Japan in 2050, and that it would be possible to produce this volume while increasing Japan's forest resources over the long term. A maximum nationwide avoided GHG emissions potential of 9.63 million t-CO 2 eq/year could be achieved in 2050, which is equivalent to 0.7% of Japan's current GHG emissions. The breakdown of avoided emissions is 73%, 19%, and 8% for carbon storage, material substitution, and energy substitution, respectively, with the greatest contributions coming from carbon storage through the use of log piles.
