“… 82 Recent studies highlight significant potentials for freshwater savings 83 but rising emissions from sludge treatment and transport. 18 The replacement of steam generation from black liquor and blast furnace gas electricity generation with natural gas could further reduce emissions due to more efficient combustion. In that case, other uses for the byproducts have to be found.…”

“… 17 assessed the opportunities for urban symbiosis in China through heat utilization and estimate a potential reduction of CO 2 emissions ranging from insignificant (1%) to up to 37% in areas close to industrial clusters, mainly realized through the utilization of low-grade waste heat and replacement of coal and natural gas in these cities. The methodology was applied to other urban clusters, e.g., for 111 Chinese Industrial Parks, 18 the cluster around Shenyang City, 19 and the Chinese cluster Yongcheng. 20 …”

In industrial symbiosis, byproducts and wastes are used to substitute other process inputs, with the goal of reducing the environmental impact of production. Potentially, such symbiosis could reduce greenhouse gas emissions; although there exists literature exploring this at specific industrial sites, there has not yet been a quantitative global assessment of the potential toward climate mitigation by industrial symbiosis in bulk material production of steel, cement, paper, and aluminum. A model based on physical production recipes is developed to estimate global mass flows for production of these materials with increasing levels of symbiosis. The results suggest that even with major changes to byproduct utilization in cement production, the emission reduction potential is low (7% of the total bulk material system emissions) and will decline as coal-fired electricity generation and blast furnace steel production are phased out. Introducing new technologies for heat recovery allows a greater potential reduction in emissions (up to 18%), but the required infrastructure and technologies have not yet been deployed at scale. Therefore, further industrial symbiosis is unlikely to make a significant contribution to GHG emission mitigation in bulk material production.

“…Finally, a feasible alternative is to foster industrial symbiosis between the infrastructures in industrial parks to reduce environmental impacts. For example, the effluent and sludge from the WWTPs and CWWTPs can be reused in the centralized energy facilities in IPs to decrease freshwater withdrawals and partly reduce fossil fuel consumption (Hu et al., 2020a).…”

As the most important production space for the development of chemical industry in China, chemical industrial parks (CIPs) are facing a new challenge of water pollution prevention and control, in addition to those posed by traditional and emerging pollutants. It is thus important to systematically reveal the compositewater‐environmental impact of CIPs for contributing to the sustainable development of the chemical industry. CIPs have the issue of intensive wastewater generation characterized by complex pollutant components and high pollution loads. Thus, establishing an environmentally friendly wastewater treatment system has always been a major challenge for CIPs. China has developed many CIPs and the two‐stage wastewater treatment system is widely employed in practice, that is, in‐plant wastewater treatment plants (WWTPs) in individual enterprises followed by centralized WWTPs in parks. Since the CIP wastewater emission limits are continuously improved, a comprehensive evaluation of the environmental impacts of the in‐use wastewater treatment system will be insightful for future policy making. This study employed life cycle assessment (LCA) to reveal the life cycle environmental impact of the two‐stage wastewater treatment system in a typical CIP. We found that the life cycle environmental impacts of the whole system mainly stem from the in‐plant WWTPs of chemical manufacturers because of chemicals and electricity consumed in the multi‐stage advanced oxidation technologies, while the increase of human toxicity potential and marine aquatic ecotoxicity potential are primarily due to sludge incineration. Three scenarios targeting the reduction of environmental impacts were proposed based on the LCA results. We evaluated the pollution mitigation potential, which can reach at most 8% of the original measured impacts. Finally, from the perspective of systematic thinking, four policy implications for improving the water management system of CIPs were proposed.

“…[ 2 ] The specific kind of symbiosis depends on whether either or both organisms benefit from the relationship, being the mutually beneficial relation known as mutualism. [ 3 ] Such relations with joint benefits are not exclusive to animals, plants, and bacteria, once they can also be found between economic models, [ 4 ] companies, [ 2 ] energy policies, [ 5 ] waste treatments, [ 6 ] biomedical strategies, [ 7 ] and industries. [ 8 ] All these different and numerous symbiosis reveal that we live in times of significant advances in society, industry, and technology, where businesses, and science are progressively working together in novel and thrilling ways.…”

In recent years, printed electronics reached enormous popularity as a result of their huge potential to offer unique features that are not attainable through traditional fabrication, namely low‐cost production, multifunctionality, stretchability, sustainability, and flexibility. Being expected a galloping increase in the use of printed technologies in the near future, due to the digitalization efforts associated with the Internet of Things and the 4.0 revolution, it is timely and desirable to discuss the joint features, the interrelations, the complementarities, the interdependency, and the most demanding challenges linked to the relation between printed technologies and electronic materials. In this context, this study offers a broad review of the numerous printing technologies used in the processing of electronics, commonly used substrates, the most effective printed electronic materials, and the key post‐printing treatments such as sintering. Disruptive challenges in various printing techniques, (un)expected future research directions of printed electronics, and imminent application trends are also highlighted, following a critical and subjective perspective.
