Resources Management & Sustainable Production
Resources & Reserves
Three key issues
Consumption of raw materials
Consumption of energy
Production of waste
Renewable and non-renewable resources
Renewable resources are those that are consumed at a lesser rate than they are replaced by natural processes.
Non-renewable resources are finite and therefore exhaustible.
Reserves are that portion of an identified resource that can be economically and legally covered.
The recycling of materials represents a way in which the materials contained within products that h ave reached the end of their useful life can be employed in new products.
Waste mitigation Strategies
Waste mitigation strategies can reduce or eliminate the volume of material disposed to landfill.
Re-use involves the repeated use of components or products employing the same or an alternative purpose than that originally specified.
Repair relates to restoring a product or component to a good or sound working condition after restoration or damage.
Reconditioning is the process by which used products may be returned to their original manufactured specification or a close approximation to it.
Re-engineer involves the revision of an established design to achieve an improvement of some sort.
Most production processes result in the creation of pollution and /or waste.
Methods of Waste Reduction
Product recovery and re-use
Avoid use of unnecessary packaging
Produce to order
Use of energy efficient equipment
It can be defined as the progressive reduction in the amount of energy and/or material used in the production of a product.
It refers to an economy based on the use of renewable sources of energy and the recycling of materials to create a sustainable economy.
Energy Utilization, Storage and Distribution
There are several factors to be considered with respect to energy and design.
It represents an assessment of all the energy associated with a product throughout its life cycle.
Local combined heat and power
The generation of electrical energy using conventional means results in a large amount of excess heat that is typically lost to the atmosphere during production.
Qualification and mitigation of carbon emissions
Human activity has been increasing the proportion of gases in the atmosphere that absorb and emit thermal radiation rather than allowing it to be re-radiated to space.
