Many industries are labor-intensive and energy- and resource-consuming. A sustainable development plan is necessary for the industries as industrial structures have been changing recently. Taiwan’s shoe industry also has experienced such changes and requires a sustainable product development plan for continuous development. Therefore, this study aims to propose a new method by introducing a model of sustainable product development to facilitate the sustainable development of the industry. By taking air-cushioned casual shoe production as an example, this study suggested the refined Kano quality model for exploring the product attributes that improved the customers’ satisfaction. The refined Kano model that was established with interviews and questionnaire surveys was effective to define the product attributes that contributed to satisfying the customers and understanding their perception of product attributes. In the air-cushioned casual shoe production, the model found function, design, innovation, marketing, and service to be important for manufacturers to develop products with limited. It also suggested the priority be put on the attributes of high value-added quality, key quality, and potential quality. The model helped manufacturers decide which product attributes they need to invest in and develop. The relation of product attributes and consumer satisfaction for a sustainable product development model was also found by using the refined Kano model. The result of this study is expected to apply to various industries for establishing an appropriate sustainable product development model.

The thermal degradation of lignin for value-added fuels and chemicals is important for environment improvement and sustainable development. The impact of pretreatment and catalysis of Ni(NO3)2 on the pyrolysis behavior of organsolv lignin were studied in the present work. Samples were pyrolyzed at 500 ∘C with an upward fixed bed, and the characteristics of bio-oil were determined. After pretreatment by Ni(NO3)2, the yield of monophenols increased from 23.3 wt.% to 30.2 wt.% in “Ni-washed” and decreased slightly from 23.3 wt.% to 20.3 wt.% in “Ni-unwashed”. Meanwhile, the selective formation of vinyl-monophenols was promoted in “Ni-unwashed”, which indicated that the existence of nickel species promoted the dehydration of C-OH and breakage of C-C in pyrolysis. In comparison with “Water”, HHV of bio-oil derived from “Ni-unwashed” slightly increased from 27.94 mJ/kg to 28.46 mJ/kg, suggesting that the lowering of oxygen content in bio-oil is associated with improved quality. Furthermore, the content of H2 in gas products dramatically increased from 2.0% to 7.6% and 17.1%, respectively.

Research background: Despite the fact, that green growth is one of the main goals of the European Union, a sufficient attention is still not given to it in conditions of Slovakia. The green growth represents compliance of the need to protect environment with economic development of society. So far, a comprehensive survey has not been carried out in Slovakia, which would focus on the issue of green growth and sustainable development in enterprises in the Slovak wood-processing industry. Purpose of the article: The aim of the presented paper is to identify key external and internal determinants preventing the implementation of green growth and sustainable development in enterprises in the Slovak wood-processing industry. Methods: Current information on the research issue was obtained through an empirical survey in the form of a questionnaire. Subsequently, the results were processed descriptively and graphically. Findings & Value added: The achieved results show that the key internal determinant preventing the implementation of green growth and sustainable development in enterprises in the Slovak wood processing industry is the orientation of production to the end of the production process in the context of environmental pollution. The enterprises consider insufficient state support to be the main external determinant.

Porous carbon materials, derived from biomass wastes and/or as by-products, are considered versatile, economical and environmentally sustainable. Recently, their high adsorption capacity has led to an increased interest in several environmental applications related to separation/purification both in liquid- and gas-phases. Specifically, their use in carbon dioxide (CO2) capture/sequestration has been a hot topic in the framework of gas adsorption applications. Cost effective biomass porous carbons with enhanced textural properties and high CO2 uptakes present themselves as attractive alternative adsorbents with potential to be used in CO2 capture/separation, apart from zeolites, commercial activated carbons and metal-organic frameworks (MOFs). The renewable and sustainable character of the precursor of these bioadsorbents must be highlighted in the context of a circular-economy and emergent renewable energy market to reach the EU climate and energy goals. This mini-review summarizes the current understandings and discussions about the development of porous carbons derived from bio-wastes, focusing their application to capture CO2 and upgrade biogas to biomethane by adsorption-based processes. Biogas is composed by 55–65 v/v% of methane (CH4) mainly in 35–45 v/v% of CO2. The biogas upgraded to bio-CH4 (97%v/v) through an adsorption process yields after proper conditioning to high quality biomethane and replaces natural gas of fossil source. The circular-economy impact of bio-CH4 production is further enhanced by the use of biomass-derived porous carbons employed in the production process.

This chapter introduces the sustainable development of county-region economy under the constraint of natural resources and environment in China when parts of classic industries along the south-eastern coast are shifting to the poorer mountain areas and middle-western areas. It argues that the county regional economic development at the stage should focus on the agricultural growing and breeding their processing sectors, natural resource exploitation and its processing, manufacturing, tourism, and ecological industrial (shift) park, according to the resource endowment. The local government should guide the scientific planning of county-region industries’ layout, structure, symbiosis, and coupling relationships. By means of environmental cost internalization, region industries’ symbiosis and coupling size, roles of social network, cultivation of innovative culture, guidance of government subsidy, pressure from public monitoring, the market mechanism, and economic incentives will play roles in resource allocation. In practice, the local government or industrial authority can design the “lack in” value chain parts and package them into some feasible and profitable projects open to the market investors, encourage firms to participate regional industrial symbiosis and coupling, and construct a complete industrial chain or network, in order to realize the integration of closed-circuit industry, higher value-added ecological agriculture, tourism and related service sectors, creative economic industrial park, urbanization, and ecological environment. This will avoid the heavy-damage from traditional industrialization and urbanization on county-regional ecological environment, and then realize the harmony development of county-regional recycle economy, society, and environment.

Pinecones, a common biomass waste, has an interesting composition in terms of cellulose and lignine content that makes them excellent precursors in various activated carbon production processes. The synthesized, nanostructured, activated carbon materials show textural properties, a high specific surface area, and a large volume of micropores, which are all features that make them suitable for various applications ranging from the purification of water to energy storage. Amongst them, a very interesting application is hydrogen storage. For this purpose, activated carbon from pinecones were prepared using chemical activation with different KOH/precursor ratios, and their hydrogen adsorption capacity was evaluated at liquid nitrogen temperatures (77 K) at pressures of up to 80 bar using a Sievert’s type volumetric apparatus. Regarding the comprehensive characterization of the samples’ textural properties, the measurement of the surface area was carried out using the Brunauer–Emmett–Teller method, the chemical composition was investigated using wavelength-dispersive spectrometry, and the topography and long-range order was estimated using scanning electron microscopy and X-ray diffraction, respectively. The hydrogen adsorption properties of the activated carbon samples were measured and then fitted using the Langmuir/ Töth isotherm model to estimate the adsorption capacity at higher pressures. The results showed that chemical activation induced the formation of an optimal pore size distribution for hydrogen adsorption centered at about 0.5 nm and the proportion of micropore volume was higher than 50%, which resulted in an adsorption capacity of 5.5 wt% at 77 K and 80 bar; this was an increase of as much as 150% relative to the one predicted by the Chahine rule.

Entropy Of Adsorption

The textural properties (surface area and porosity) of activated carbons change upon treatment with oxidizing solutions. The extent of this change is related to the strength of the oxidizing agent. Oxidation also changes the chemistry of the surface by forming carbon–oxygen groups which are the sites upon which the initial adsorption of water vapour takes place. The adsorption of water vapour at 300–320 K is mainly physical and the isosteric heat of adsorption decreases continuously as the surface coverage increases. The entropy of adsorption of water vapour on untreated and oxidized carbons, at different adsorption temperatures, has been calculated.

The chestnut tree has characterised the social history of the Italian hills and mountains. However, in recent years, this resource has been abandoned because of the change in socio-economic needs. The aim of this study is twofold: (i) To give an overview of this resource, assessing the strengths-weaknesses-opportunities-threats of the chestnut tree through the use of the SWOT methodology; (ii) to provide action strategies for resource valorisation, in accordance with the SDGs set out in the UN 2030 Agenda, by using the TOWS methodology. Our results suggest four strategies, specifically; ‘resource-based’, ‘network-based’, ‘policy-based’ and ‘market-based’, capable of valorising the resource from environmental, economic and societal points of view. The active management of chestnut forests, together with the development of a value chain can guarantee sustainable production, technological and process innovation and could empower companies to face global markets in a more competitive way and lead to the creation of high value-added products, generating a strong economic and social engine for the revival of the sector. Moreover, the commitment of the private sector to the reorganisation of the supply chain must also be accompanied by coherent public policy action. This is essential for the adoption of plans and programmes consistent with sustainable development objectives, ensuring their prioritisation and implementation.
