Strategy to derive benefits of radical Cleaner production, products and technologies: a study of Indian firms
Journal of Cleaner Production, 2016Co-Authors: Kumar Verma Bhupendra, Shirish SangleAbstract:Cleaner Technology strategy is a firm's long term planning to avoid negative externality to the natural environment and remain competitive in future markets. The paper proposes a comprehensive definition of Cleaner Technology strategy and presents its important aspects to derive competitive advantages based on an empirical study of sixty firms across the industry sectors in India. A measure of Cleaner Technology strategy was constructed and, tested for its reliability and validity. Descriptive statistics was used to understand the relative importance of competitive aspects of Cleaner Technology strategy in Indian firms. The result shows that Cleaner Technology strategy derived from top management's vision of future technologies and ability to manage risk due to natural environment play a critical role in implementation of Cleaner Technology strategy. Firm's ability to pursue regulators for additional benefits, ability to manage risk associated with failures and imitation, and focus on up-gradation of in-house technological capabilities help in re-positioning to derive competitive advantages. The results also indicate that sustainable solutions offer differential competitive advantages across the industry sectors and firm's focus to update skill set of employees is also linked with industry sectors. The paper contributes to existing literature by making distinction between Cleaner Technology strategy and other strategies like pollution prevention and product stewardship. It further argues the strategic perspective of Cleaner Technology, Cleaner production and eco-friendly products to develop necessary attributes for competitiveness. It also provides a measurement tool for the managers to check the performance of their firm to achieve the goals of Cleaner Technology strategy. Further, the paper provides important managerial, policy and research implications.

what drives successful implementation of pollution prevention and Cleaner Technology strategy the role of innovative capability
Journal of Environmental Management, 2015Co-Authors: Kumar Verma Bhupendra, Shirish SangleAbstract:Firms that are dynamic and prepared to implement environmental strategies have a potential competitive advantage over their industry counterparts. Therefore, it is important to understand, what capabilities are required to implement proactive environmental strategies. The paper discusses the attributes of innovative capability required by firms in order to adopt pollution prevention and Cleaner Technology strategies. Empirical results show that process and behavioral innovativeness are required by firms to implement a pollution prevention strategy. In addition to process and behavioral innovativeness, firms need a top management with high risk-taking ability as well as market, product, and strategic innovativeness to implement a Cleaner Technology strategy. The paper proposes some important managerial implications on the basis of the above research findings.

Adoption of Cleaner Technology for climate proactivity: a Technology–firm–stakeholder framework
Business Strategy and The Environment, 2010Co-Authors: Shirish SangleAbstract:The adoption of Cleaner Technology (CT) has the potential to play an important role in tackling the impacts of business on climate change on business. It is therefore important to understand the factors motivating the adoption of CT in business. Using a Technology–firm–stakeholder framework, this study proposes a perception-based model for the adoption of CT for climate proactivity that is tested against data collected from 106 firms in India. Six factors are tested using a logistic regression and five are found to be significant in distinguishing adopter firms from non-adopter firms. The results suggest that the perception-based model using a Technology–firm–stakeholder framework is a useful approach for examining factors affecting the adoption decision. While techno-economic benefits are perceived to be higher by adopter firms than by non-adopter firms, other benefits are not perceived differently by either adopter or non-adopter firms. In addition, adopter firms perceive lower financial costs and higher technical capability than non-adopter firms do. Also, adopter firms perceive higher regulatory pressure but lower stakeholder pressure than non-adopter firms do. Implications of the findings and future research areas are discussed.

Steady state analysis of membrane processes for the treatment of industrial effluents
Computer-aided chemical engineering, 2007Co-Authors: Ana M. Eliceche, Sergio M. Corvalan, Inmaculada OrtizAbstract:Publisher Summary This chapter discusses the steady state analysis of membrane processes for the treatment of industrial effluents. The feasibility of operating a new membrane Technology for the treatment of industrial effluents in a continuous mode is analyzed. The selection of the operating mode needs to be addressed at the conceptual design stage. The semicontinuous operation and the optimum operating conditions are reported. A steady state configuration is proposed, the corresponding modeling equations are developed, and a methodology for the selection of the operating conditions is presented. A given compound can be removed from the effluent in the extraction module, and simultaneously, it can be recovered in the stripping module, for recycling and reuse in the plant that generates the effluent. Environmental applications of this Technology will reduce the amount of contaminant disposed off finally into the environment, leading to a Cleaner Technology. This fact motivates the need to promote its industrial application. The removal and recovery of Cr(VI) from surface treatment effluents is studied.

Minimum membrane area of an emulsion pertraction process for Cr(VI) removal and recovery
Computers & Chemical Engineering, 2005Co-Authors: Ana M. Eliceche, Sergio M. Corvalan, M. Fresnedo San Román, Inmaculada OrtizAbstract:The design of an emulsion pertraction membrane (EPM) process for the treatment of wastewater containing hexavalent chromium and its recovery for industrial reuse is presented. EPM is a new Technology that combines the efficiency of emulsion liquid membranes with the advantages of using hollow fibber membrane modules. It can selectively remove and concentrate metals from diluted process streams. The total membrane required is minimised, complying with effluent disposal regulations and concentrations levels for Cr(VI) reuse. The algebraic and differential equation system modelling the mass transfer along the membrane modules is presented. The differential equations are discretised using orthogonal collocation on finite elements to solve a non-linear programming problem. An improved process configuration recycling the treated wastewater and eliminating fresh water consumption is presented. The sensitivity of the objective function to emulsion tank volumes and aqueous to organic phases ratio in the emulsion are quantified suggesting further improvements for the industrial application of this Cleaner Technology.

Optimal design of membrane processes for wastewater treatment and metal recovery
Computers & Chemical Engineering, 2004Co-Authors: Sergio M. Corvalan, Inmaculada Ortiz, Ana M. ElicecheAbstract:Different continuous operating modes of a nondispersive solvent extraction (NDSX) process with membrane modules of hollow fibre for wastewater treatment and metal recovery are evaluated. Cocurrent and countercurrent flow of aqueous and organic phases in the membrane modules with alternative product extraction locations for the removal and recovery of hexavalent chromium from wastewater are studied. The design of NDSX process in a countercurrent continuous operation is addressed for the first time in this work and the improvement achieved is reported. The membrane area required in the countercurrent operation is reduced significantly compared with the cocurrent operation, requiring also less investment in pumps and pumping cost leading to the minimum total cost. Thus a significant improvement in the design of this new and Cleaner Technology is presented. # 2003 Elsevier Ltd. All rights reserved.

Optimal transition to renewable energy with threshold of irreversible pollution
European Journal of Operational Research, 2016Co-Authors: Noël Bonneuil, Raouf BoucekkineAbstract:When cheap fossil energy is polluting and pollutant no longer absorbed beyond a certain concentration, there is a moment when the introduction of a Cleaner renewable energy, although onerous, is optimal with respect to inter-temporal utility. The Cleaner Technology is adopted either instantaneously or gradually at a controlled rate. The problem of optimum under viability constraints is 6-dimensional under a continuous-discrete dynamic controlled by energy consumption and investment into production of renewable energy. Viable optima are obtained either with gradual or with instantaneous adoption. A longer time horizon increases the probability of adoption of renewable energy and the time for starting this adoption. It also increases maximal utility and the probability to cross the threshold of irreversible pollution. Exploiting a renewable energy starts sooner when adoption is gradual rather than instantaneous. The shorter the period remaining after adoption until the time horizon, the higher the investment into renewable energy.

Technological vs ecological switch and the environmental Kuznets curve
2011Co-Authors: Raouf Boucekkine, Aude Pommeret, Fabien PrieurAbstract:We consider an optimal Technology adoption AK model in line with Boucekkine Krawczyk and Vallée (2011): an economy, caring about consumption and pollution as well, starts with a given technological regime and may decide to switch at any moment to a Cleaner Technology at a given permanent or transitory output cost. At the same time, we posit that there exists a pollution threshold above which the assimilation capacity of Nature goes down, featuring a kind of irreversible ecological regime. We study how ecological irreversibility interacts with the ingredients of the latter optimal technological switch problem, with a special attention to induced capital-pollution relationship. We find that if a single technological switch is optimal, one recovers the Environmental Kuznets Curve provided initial pollution is high enough. If exceeding the ecological threshold is optimal, then the latter configuration is far from being the rule.

Environmental quality versus economic performance: A dynamic game approach
Optimal Control Applications and Methods, 2011Co-Authors: Raouf Boucekkine, Jacek B. Krawczyk, Thomas ValléeAbstract:We study a trade-off between economic and environmental benefits using a two-stage optimal control setting where the player can switch to a Cleaner Technology that is environmentally ‘efficient’ but economically less productive. We provide an analytical characterization of the solution paths for the case where the considered utility functions are increasing and strictly concave with respect to consumption and decreasing linearly with respect to the pollution stock. We establish that in this context, an isolated player will either immediately start using the Cleaner Technology or for ever continue applying the old ‘dirty’ Technology. In a two-player dynamic game (between two neighboring countries) where the pollution results from a sum of two consumptions, we prove existence of a Nash (open-loop) equilibrium, in which each player chooses the Technology selfishly, i.e., without considering the choice made by the other player. A Stackelberg game solution displays the same properties. Under cooperation, the country reluctant to adopt the clean Technology under autarky will adopt the Cleaner Technology provided it benefits from some ‘transfer’ from the more environment-friendly partner.
