Green innovation and firms’ financial and environmental performance: The roles of pollution prevention versus control

This study examines the effects of firms' green innovation on their future financial and environmental performance. If pollution is primarily a manifestation of wasted resources, then investments in pollution prevention technologies can both reduce the environmental impact of production and improve financial performance. In contrast, investments in pollution control technologies likely reduce the environmental impact of production without improving financial performance. Using green patents to capture firms' investments in these two types of technologies, we find that the value of a firm's pollution prevention patents is positively associated with its future financial and environmental performance, and that the positive impact on future financial performance is achieved through improvements in sales growth and cost efficiency. In contrast, the value of a firm's pollution control patents is not associated with its future financial or environmental performance. Overall, these findings shed light on the future implications of green innovation.

Research And Impact of Bioremediation on Soil Cadmium

There are many studies on the interaction between Cd pollution and bioremediation at home and abroad, mainly local and short-term toxicological effects, and there is a lack of systematic reviews. The purpose of this report is to provide a summary of the research on several bioremediation methods through specific experiments and mechanisms. and a summary and report on the principles and mechanisms of phytoremediation technology and animal remediation technology. In the future, bioremediation technology should focus on further exploration in the treatment cycle and final treatment of materials, avoid secondary pollution, strengthen the prevention and control of soil cadmium pollution, master more scientific soil cadmium pollution prevention and control technology, and expand more experiments and research on bioremediation If necessary, researchers can comprehensively apply and match a variety of different control technologies to enhance the control effect of soil cadmium pollution. It is also hoped that more attention will be paid to some potential future research on remediation methods for soil cadmium pollution, and that bioremediation is not only for the further exploration and discovery of cadmium and other heavy metal pollution in soil.

Synthesis of Air@Co@Co7Fe3@Fe3O4 composite with enhanced electromagnetic wave absorption performance

Electromagnetic pollution prevention and military stealth technology requirements for wave absorbing materials gradually increased, therefore, the research and development of absorbing materials with the merits of low reflection loss, wide effective absorption bandwidth, and lightweight is of great significance. In this work, Air@Co@Co7Fe3@Fe3O4 hollow spherical particles have been successfully synthesized via a simple chemical plating method combined with a post heat treatment. It reveals that the Air@Co@Co7Fe3@Fe3O4 particles with a loading of 50 wt % exhibits an optimum reflection loss (RL) value of −20.77 dB at 15.52 GHz and broad effective absorption bandwidth (EAB, RL ≤ −10 dB) of 4.56 GHz with a thickness of 1.4 mm. Compared to Air@Co hollow spherical particles, Air@Co@Co7Fe3@Fe3O4 particles with natural resonance and eddy current loss, as well as the interlayer interfacial polarization mechanism of the multilayer structure, exhibit superior electromagnetic wave(EMW) absorption capabilities. The Air@Co@Co7Fe3@Fe3O4 hollow spherical particles could be a new highly efficient absorbing material for electromagnetic waves.

New Trends in Pollution Prevention and Control Technology for Healthcare and Medical Waste Disposal in China

This study explores the progression of global healthcare and medical waste (HMW) disposal technologies and emerging practices in China including the COVID-19 pandemic period through patent technology innovation analysis. Trends were identified through both the Derwent Innovation Index database and bibliometric methods. Based on the bibliometric analysis of 4128 patents issued from 2002 to 2021, the development status and research trends of HMW disposal technology were revealed. Regarding patents, China significantly advanced post-2011. However, a large number of applications are filed only in China and are more focused on domestic rather than overseas markets. As the pandemic remains a threat, and increasing amounts of medical waste are generated, new technologies are being sought in China that will be safer for humans and the environment, and will also be in line with the zero waste technology trend. Incineration and waste crushing are core methodologies in medical waste disposal. Future directions pivot towards innovations in large-scale and distributed processing equipment, automation and unmanned systems and high-temperature steam disinfection collaborative disposal methods—including the “High temperature steam–municipal solid waste incineration collaborative technology” and the “High temperature steam–thermal magnetic gasification collaborative technology”. This patent analysis enhances our understanding of the impact of COVID-19 on HMW disposal practices, guiding improved policymaking and research in the HMW sector.

An enquiry into competitive value of sustainable manufacturing capabilities

PurposeDespite its great practical and theoretical significance, research on how and to what extent sustainable manufacturing capabilities (SMCs) provide competitive advantage to firms remains scarce. Towards bridging the gap, this paper conducts an enquiry into the competitive value of SMCs.Design/methodology/approachA theoretical framework on the competitive value of four SMCs, namely, pollution control (PC), pollution prevention (PP), product stewardship (PS) and clean technology (CT) is developed through synthesis of literature. More specifically, competitive value is characterised in terms of enabling key resources and market positioning opportunities. A case study, using a deductive qualitative approach is conducted to test the framework by analysing reported sustainable manufacturing practices (SMPs) of three multinational firms. Observed compliances and deviations to the framework are analysed and accordingly few propositions are framed.FindingsThe empirical findings largely support the conceptualisation of competitive value for PC, PP, PS and CT provided in the theoretical framework. However, a few deviations were observed for PC, PP and PS. For instance, some PC-based actions, such as co-processing and implementation of zero liquid discharge technology show characteristics of resource conservation and lead to cost benefits. Similarly, there were instances when PP demonstrated the use of non-tacit (imitable) resources and PS was employed to seek compliance to environmental regulations.Research limitations/implicationsThe results based on limited number of case firms may not be generalisable to other sectors and contexts.Practical implicationsThe study provides guidance to the manufacturing managers about the competitive value of SMPs.Originality/valueThis is a novel study that empirically investigates the competitive value of SMCs by understanding the associated sustainability impetus, enabling key resources and market positioning opportunities.

Research Progress and Trend of Agricultural Non-Point Source Pollution from Non-Irrigated Farming Based on Bibliometrics

The agricultural non-point source (NPS) pollution caused by non-irrigated farming, such as heavy metals, nitrogen and phosphorus, has posed an extreme threat to the security of agricultural product quality and watershed ecology. Thus, it is urgent to sort out the latest research progress and future development trend to effectively guide future scientific research and technological updates in this field. This study integrates the relevant literature of the Web of Science from 1976 to 2021 and analyzes the research hotspots and development trends in the field of agricultural NPS pollution from non-irrigated farming in combination with CiteSpace. The results showed that the proportion of publications from the United States and China accounted for 58.4%. Science of the Total Environment, Water Science and Technology and Journal of the American Water Resources Association were the most published journals. The research topics and hotspots mainly involve agricultural NPS pollution prevention technology, pollution source identification, pollution load and management and landscape pattern evolution. In the future, agricultural NPS pollution research in non-irrigated farming should combine agricultural big data platforms, spectroscopic methods, artificial intelligence technology, etc. and focus on strengthening soil testing formula fertilization management, the efficient use of livestock and poultry breeding manure, climate change and risk early warning.

The Deficiencies in research and development of Plastic Pollution Prevention Technologies

As the urgency of the plastic pollution problem increases, researchers are devoting more attention to technological solutions for combating it. However, this research and associated technological developments have failed to produce satisfactory results. One observes this in steadily increasing ocean plastic content and plastic inflow rates. Many factors are responsible for the persistence of the plastic pollution issue, such as insufficient government regulations (Testa et al.) and profit-motivated resistance to clean transitions on the part of companies (Rogers et al.; Meredith). However, this opinion paper is going to focus on several in particular: 1) insufficient analysis aimed at explaining the success or failure of existing products. 2) little cooperation between the NGOs and companies doing this research, and between these organizations and the government. 3) a lack of category-spanning research and analysis concerning plastic pollution prevention technologies. All of these factors are pivotal for productive future technological development, especially when it comes to technologies.

Promoting sustainable development through strategies, environmental management accounting and environmental performance

AbstractExtant research on environmental management accounting (EMA) has mainly emphasised its impact on environmental disclosures and cost measurements, while the role of EMA in environmental performance has largely been neglected. Hence, the study addressed the literature gap by applying the natural resource‐based view (NRBV) and the dynamic capabilities (DC) theory to investigate EMA as a fundamental managerial innovation mechanism that explains the relationship between environmental strategies and environmental performance. Questionnaires were used to gather data from 145 managers of ISO14001‐certified Malaysian companies. The results of the Partial Least Squares Structural Equation Modelling (PLS‐SEM) analysis demonstrated that EMA mediates the effects of pollution prevention and clean technology strategies on environmental performance but not the effect of the process stewardship strategy. The findings encourage companies to adopt specific environmental strategies to attain better environmental performance through EMA. Moreover, the results highlighted the company limitations in improving environmental performance. The study is one of the first few attempts to integrate EMA with environmental strategies through the application of the NRBV and the DC theory. Additionally, the study provides empirical evidence that efficient EMA management can be transformed into reasonable operational performance and produce positive outcomes.

Tail risk dependence, co-movement and predictability between green bond and green stocks

ABSTRACT This paper examines the coherence of extreme returns between green bonds and a unique set of green stocks. We use the novel quantile cross-spectral coherence methodology of quantile spectral coherency model, cross-quantilogram correlation approach, windowed time-lagged cross-correlation, and windowed scalogram difference models as estimation techniques. The study period spans from 28 November 2008 to 23 September 2020. Our measure of green stocks comprises the constituents of the MSCI Global Environment Price Index: Alternative Energy, Green Building, Pollution Prevention or Clean Technology while our green bond market is proxied by S&P Green Bond Index. We find the dependency between Green Bonds and green stocks to be weak, and this is high during market downturn periods in the short- to medium-term dynamics. This suggests that Green Bonds do act as a hedge, diversifier, or safe-haven instrument for environment portfolio in the short-term, medium-term and long-term dynamics during bearish market conditions. We conclude that green bonds and green stocks are two distinct asset classes with a distinct risk-return profile despite their common climate-friendly nature.

Building Green Smart City Capabilities in South Sumatra, Indonesia

Information and communication technology is currently developing rapidly. It has created a great number of opportunities for governments worldwide to meet the demands of the public in providing services including environmentally friendly public services for the community and citizens. This study aims to present a case study on public services of South Sumatra government programs in order to develop a green smart city concept by combining smart city and green IT concepts which aim to align and incorporate green IT components, including pollution prevention, product stewardship, and clean technology into conceptual variants, essential elements, and strategic principles. A smart city is an innovative and modern concept utilising technology to facilitate and provide public information and to improve environmentally friendly public services through smart applications. South Sumatera is one of the provinces in Indonesia that has been implementing a smart city to provide environmentally friendly public services through the command centre. It is used to monitor an entire government agency’s activities and communicates with the public. To fulfil the aims of the study, this study identifies the comprehensive environmentally friendly public services through Natural Resource-Based View Theory perspectives. In addition, this study deploys in-depth interviews with sources or informants as a form of data search and direct observation. The number of informants used as research respondents consisted of several elements of the government, including the executive, legislative, and implementing agencies. The study reveals that the South Sumatera Government has several environmentally friendly public services that could be deployed to prevent pollution and reduce the emission in their activities. Further, the government in South Sumatra has product and service stewardships and invests in clean technology to minimise the adverse impacts of their activities on the environment.

RETRACTED ARTICLE: Environmental regulation of PM2.5 in urban green vegetation and the influence of green technology progress based on remote sensing image

In the face of increasingly serious environmental problems, Chinese governments at all levels have issued a series of regulatory measures for energy conservation and emission reduction. The rational use of science and technology can not only improve environmental quality but also promote rapid economic development. In order to encourage and guide the development of green technology and drive the collaborative progress of preventive technology and processing technology, it is necessary to develop the green technology progress-oriented function of environmental regulation and explore its transmission mechanism. This paper analyzes the relationship between environmental regulation policy and green technology progress. The results show that environmental regulation policy is an effective way to promote the progress of green technology.; The regulation policy combination of environmental tax and environmental subsidy can effectively improve social welfare, which is embodied in the increase of output, the reduction of production cost, and the reduction of pollution caused by the coordinated progress of pollution prevention technology and pollution treatment technology. Through the means of spatial planning, we can provide the construction ideas with urban characteristics for the ecological city represented by vegetation coverage. We can improve the urban greening by inserting green in the cracks; we can also build various types of large-scale urban green belts by increasing urban farmland, so as to improve the construction of urban ecosystem.

Wind power projects in Brazil: challenges and opportunities increasing co-benefits and implications for climate and energy policies

The purpose of this article is to analyze the challenges to, and opportunities for, increasing sustainable development (SD) co-benefits delivered by clean development mechanism (CDM) wind power projects in northeastern Brazil and the resulting implications for climate and energy policies. Five methodological phases were met: First, a documentary research was conducted in the main CDM database; second was a literature review, creating the analytical framework and a survey questionnaire needed to assess the SD co-benefits from the projects; third, documentary research was used to enable ex-ante analysis of the SD co-benefits proposed in the CDM Project Design Documents (PDDs); fourth, survey allowed for the analysis of SD co-benefits perceived by project entrepreneurs (ex-post analysis); and finally, a comparison between the ex-ante and ex-post analyses was completed. The results show the importance of carrying out SD co-benefit studies after the implementation of CDM projects in order to learn lessons for new mechanisms of climate governance. The lowest SD co-benefits were water management improvement in the project influence area, soil pollution prevention, health and safety improvements and technology transfer. The greatest opportunities for increasing SD co-benefits come from the environmental licensing process and the strengthening of Corporate Social Responsibility. The greatest challenges are new technology development, stakeholders’ engagement and SD co-benefit audits. We conclude that the improvement of multi-level climate and energy governance plays a key role in increasing SD co-benefits.

Exploring the Effects of the Best Practices of Environmental Management on Green Product Development

The attention of corporate environmental management is shifting from clean technologies and pollution prevention to green product development (GPD). As a result, firms consider GPD critical for their increased productivity, cost reduction, better use of input resources, mitigation of waste disposal and become environmentally friendly. This study measures the effects of the best practices of environmental management – pollution prevention technologies, innovation and early timing – on GPD; and to analyze whether the moderating role of organizational capital strengthens/weakens that relationship. Data was collected systematically from companies involved in GPD in Thailand. Hierarchical regression techniques were used for data analysis. Findings revealed positive effects of innovation in pollution prevention technologies and early timing on GPD. And the interaction of organizational capital further strengthened the effects early timing had on GPD. Contrary to research hypothesis, pollution prevention technologies did not facilitate GPD. Data didn’t reveal the moderating effects of organizational capital on the relationship between pollution prevention technologies, innovation in pollution prevention technologies and GPD. Although, I did not hypothesis for the organizational capital, yet data revealed its direct impact on GPD. The findings also discuss the theoretical and managerial implications for modern managers.

An empirical explanation of the natural-resource-based view of the firm

To date, the natural-resource-based view has been an abstract phenomenon, primarily used by academics to explain competitive sustainable operations. This paper attempts to go beyond this, responding to the need for an explanation of the practical existence of the four natural-resource-based view resources in industry. Assuming a critical realist qualitative approach, in-depth interviews with sustainability experts in UK agri-food are undertaken. Findings demonstrate the existence of pollution prevention, product stewardship, and clean technologies and align with Hart’s conceptualization of sustainability as competitive resources. Whilst the fourth resource, the base of the pyramid, cannot be empirically verified, the fifth resource of local philanthropy is uncovered and contributes to the growing body of knowledge surrounding competitive social sustainability. Findings also challenge the hierarchal presentation of the natural-resource-based view to implicate a more cyclical uptake. Thus, in offering the first empirical explanation of the natural-resource-based view, this paper overcomes a theory-practice gap to elucidate the feasibility, orchestration, and value of resources in competitive and sustainable operations.
