The development of eco-industrial parks is now proven a local efficient solution to reduce environmental impacts of industrial areas as well as increasing economic benefits. Furthermore, they are a good way to produce goods while reducing environmental footprints by exchanging energies, water and raw materials instead of consuming too much resource...

Climate change and rapid population growth have caused a steady rise in the global demand of water, energy and food. Various review articles have studied this effect through the water-energy-food nexus (WEFN) topic from different aspects, including flow quantification and policy making, among others. Optimization models have also been formulated re...

Industrial systems are complex in terms of types of material exchanged (water, electricity, vapour…), types of industries involved, and size of companies, temporality and many others. Regarding this complexity, this paper aims at developing a generic methodology able to design exchanges between companies in an eco-industrial park in terms of electr...

By gathering in Eco-Industrial Parks (EIPs), companies obtain benefits from synergistic cooperation but it also creates a risk by increasing interdependencies.

An Eco-Industrial Park (EIP) is a community of businesses that seeks to reduce the global impact by sharing material. The connections among the industrial participants within this park improve the environmental performance of the industrial network. However, the connectivity also propagates failures. This risk is an important point of criticism and...

A multi-leader-follower game (MLFG) model for the design of the utility network in an eco-industrial park (EIP) is studied and implemented by introducing the concept of an environmental authority.

Nowadays, many Eco-Industrial Parks (EIP) are emerging all around the world. In these eco-industrial parks, industries gather to share several streams like energies, water, resources, and wastes in order to realise economic benefits while lowering their environmental impact. However, most of the time, these EIP are historically constituted and ther...

Water, as everybody knows, is a limited and fragile resource. In fact, water faces several challenges in the future due to the increase of population, pollution, climate change, etc. To overcome these problems, some concepts linked to sustainable development such as “Industrial Ecology” have emerged. The concept of industrial ecology is defined as...

The increased use of carbon fibre reinforced polymers (CFRP) has raised the environmental concerns on waste disposal and consumption of non-renewable resources as well as economic awareness for the need to recycle CFRP wastes stemming from aircraft. This study develops an optimisation approach of CFRP waste management with the simultaneous objectiv...

Project developer in the domain of land settlement project are involved with many stakeholders and are usually overflown by data relative to technical, economic and social issues. This paper contributes to the necessary multi-scale approach challenge and we propose a holistic framework that enables to describe the development process of land settle...

Industrial symbiosis offers to companies the possibility to make economic benefits and to minimize environmental impacts by sharing flows and increasing inter-enterprise exchanges. However, even if some studies have demonstrated the benefits of the development of eco-industrial parks (EIP), there is no consensus to evaluate their benefits in a glob...

Any sustainable land settlement project should consider social and environmental issues along with usual technico-economic issues. That complexity prompts us to propose a metamodel framework (Roth et al., 2017), and support it with a generic core metaontology shown in this work. It is further instantiated into four issues, stakeholders, layers and...

An Eco-Industrial Park (EIP) is a community of businesses that seeks to reduce the global impact through material sharing. Even though an EIP presents an environmental improvement when compared with a set of stand-alone industrial plants, the established connections among the industrial participants can propagate failures, and become in a source of...

The design and optimization of industrial water networks in eco-industrial parks is studied by formulating and solving multi-leader-follower (MLFG) game models.

Results are represented on Pareto fronts for each number of connections. Networks proposed are optim...

This paper presents a multiobjective MILP formulation for optimizing industrial water networks. By expressing balance equations in terms of partial mass flows instead of total mass flows and concentrations, and because the contaminant mass flow (ppm) is very small compared to the water mass flow (T.h-1), the problem becomes linear. The integer vari...
