Designing SIA - Technical infrastructure
Outline
Operators (management companies) of industrial sites often tend to restrict themselves to the building of roads and the provision of energy and water. To foster sustainability a wider approach is necessary which comprises all aspects of infrastructure and logistics, supply of energy, water and goods, collection and treatment of effluents and waste as well as provision of communication networks and social services. Depending on the local framework conditions and the business concept of the park management, individual services can be tendered to sub-contractors supervised and monitored by the park management.
Key Elements
Infrastructure for passenger and goods transport:
A sustainable infrastructure provision is based on a well-designed site master plan, which includes roads capable to accommodate the foreseeable development of traffic as well as bicycle and pedestrian infrastructure, access points and parking areas to manage the stationary traffic. Apart from the general road transport, the entire logistic of goods entering or leaving the park has to be taken care of. This includes the management of entry points like harbours, train terminals, warehouses or other types of logistic hubs, transport facilities like pipelines for gases and liquids, conveyor belts for bulk material and respective storage, loading and pumping facilities. To assure reliable, safe, comfortable and affordable commuting towards and within the industrial area an efficient passenger transport system is required. It should consider all means of transport (pedestrian, bicycle, scooter, car, bus, tram, metro), but from the ecological point of view, it should give priority to public mass transport systems (bus, tram, metro).
Provision of energy:
Energy supply and distribution needs to be based on an integrated system of incoming energy from outside the park and energy generation including utilisation of waste energy in the park. The management company has various options to supply energy to its customers at favourable prizes. It may buy energy in large quantities from external suppliers or generate energy internally from conventional fuels, renewable energy sources and waste or utilise waste energy, heat and steam coming from the resident companies. This requires of course an integrated electricity, gas and steam distribution network operated by a single entity, ideally the management unit itself.
Provision of water:
The scarce resource "water" should be addressed in a holistic water and wastewater management approach. Responding to the different demands for drinking and process water needed by the companies in the industrial area, several water qualities must be offered, ideally in a cascading way based on re-use concepts to save water. An analysis of the water distribution system forms the basis for identifying the requirements of the industry and existing water saving potentials. Advice and support to reduce water consumption and reuse wastewater is given to companies to raise awareness in the industry. Rainwater harvesting should be practiced on park facilities, and the collected water should be made available (after conditioning) to the companies for production purposes.
Surface and wastewater management:
Generally, measures have to be introduced to prevent wastewater generation and to reuse wastewater (after treatment) as best as possible before disposal options are considered. Due to the different levels of contamination wastewater treatment needs to be accommodated to the releasing industries as well as to the requirements of the companies reusing wastewater. Companies that generate intensively polluted wastewater need to install a pre-treatment facility before they are allowed to discharge their wastewater into the common sewer. Wastewater of the common sewer is treated in common effluent plants. A good functioning wastewater and surface water system needs clean and proper designed drains. Depending on the magnitude of expected rainfalls it might be advisable to separate the surface water from the industrial wastewater to not overload the effluent plants.
Waste collection, treatment and disposal:
Waste management in sustainable industrial areas should follow the principles of the waste management hierarchy which gives avoidance of waste, reuse, recycling and conversion into energy priority to incineration and disposal. In order to set up such a system, the park management needs to offer advice on how to prevent, minimise and separate the waste within the companies. Furthermore, it provides joint service facilities at park level for the collection, treatment, recycling and disposal of the different types of waste including those which are
hazardous. To design an appropriate waste management system the waste flows in the park have to be analysed. For those waste components which are considered a resource ecological and economic sound solutions have to be offered to use these resources within the area (e.g. within networks of industrial symbiosis or loops of circular economy) or to market them as secondary raw material.
Social infrastructure:
Basic social infrastructure should cover catering, small shops or kiosks and communication facilities. Especially for risky work conditions adequate medical services are necessary. Educational and training institutions specialised to train apprentices and employees of the industry sectors settled in the park are very important and may be one key success factor. If many workers live with their families close to or on the premises of the park, the question of schools for children needs to be addressed. Adequate child care facilities are required, in particular to enable mothers to work. If the park is regarded a development zone, the basic facilities need to be complemented by further shopping and banking facilities as well as recreational and sports facilities. In providing a cultural infrastructure (e.g. cinema, cultural events, and congregation space) the areas can play an important societal role.

Co-Processing of Waste Materials in the Cement Industry
In a joint initiative the Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH (GIZ) and Holcim Group Support LTD (Holcim) have developed Guidelines on Co-Processing Waste Materials in Cement Production which provide information on the use of waste material as an alternative resource for energy and material recovery in an environmentally sound manner. Additionally, GIZ and Holcim have developed and compiled a modular training kit designed to teach relevant staff from the public and private sector on the topic of co-processing. The training kit takes into consideration the specific framework conditions in emerging and developing countries and will enable participants to understand the benefits, risks and opportunities of co-processing as a contribution towards sustainable development.

Sustainability Calculator for Industrial Areas
The Sustainability Calculator for Industrial Areas has been designed to guide the decision making of developers and managers of Industrial Areas (IA), who want to improve environmental and social impacts of their IA, increase their competitiveness in international markets and attract new investors and clients by integrating profitable voluntary measures into the design and management of their IA. The results generated by this tool allow estimating the potential economic benefits of voluntary investments into improving the sustainability of a IA. Additionally, they visualize the impact of potential investments on the sustainability of an IA, generating a diagram for the user that assists in identifying voluntary measures that impact positively on the sustainability of your area while simultaneously generating profits.
The calculator offers measures that can be applied to both new and existing IAs that wish to improve their performance. The tool is embedded in a web page with further information re Sustainable Industrial Areas, Testimonials from other industrial zone developers and managers re the benefits they were able to reap by investing in specific sustainability measures, and contact information for international and local experts. -

Wastewater management in industrial parks
Common effluent collection and treatment systems in industrial parks are often either not existing, dysfunctional or not functioning properly in many developing countries. The causes are diverse and must be thoroughly examined from case to case.
The tool includes case studies, best practice examples and management manuals elaborated by GIZ and KfW projects in various Asian countries.
