Study Notes

Waste Stream Recycling and Recovery

Recycling is a useful application of the waste stream.
Recycling should be implemented at the facility where the waste stream is generated, to eliminate the need for transportation.

Cleaner Production

Cleaner production includes on-site reuse and recycling, as a part of its approach.
Cleaner production strategies aim to:
- Reduce material intensity - make more products with fewer inputs.
- Reduce energy consumption - make more products with less energy.
- Reduce dispersion of toxic substances - make more products but pollute less.
- Enhance recyclability - make products recyclable.
- Maximise use of renewables - make product with materials that won't deplete.
- Extend product durability - make products that last longer.
- Increase service intensity - meet demand with service, not with more products.
Benefits of cleaner production include:
- Cost savings - less waste, reduced material inputs.
- Improved risk management - reduced risk and liabilities.
- Marketing advantage - Innovation and competitiveness.
- Human resource benefits - better morale, loyalty.
- Value creation and protection - improved quality and safety = improved shareholder value.

Eco-efficiency

Eco-efficiency suggests that growth in consumption of goods and services should be accompanied by a proportional decline in energy and material intensity.
Eco-efficiency can be negated through the 'rebound effect' - e.g. biofuel cars = more car usage or expensive food.
Eco-efficiency focuses on maintaining or increasing economic value while decreasing ecological impacts.
Eco-efficiency focuses on economic efficiency delivering environmental benefits.

Eco-effectiveness

Eco-effectiveness seeks to emulate nature, where "waste equals food." (Zero-waste thinking)
Eco-effectiveness requires businesses to reinvent themselves and contribute less to resource depletion.
Eco-effectiveness defines a positive agenda working towards a "100% positive" system.
Cradle to Cradle (C2C) certified products are an example of a circular economy in action.
C2C certified products are:
- Safe for both human and environmental health - no toxicity, biodegradable, etc…
- Designed for easy recovery and reuse of materials.
- Based on renewable energy and resources.
- Water-wise.
- Socially responsible.

Environmental Management Systems (EMS)

EMS is an integrated environmental strategy to focus on industrial processes, increasing efficiency and reducing socio-environmental risks.

Pollution Reduction Principles

Polluter pays principle: The polluter is liable for any social or environmental damage caused by pollution.
Cradle to grave principles: Using life cycle assessment to find ways to minimize pollution associated with business activity.

Cleaner Production in Industry

Cleaner production is an integrated preventive environmental strategy applied to processes, products, and services.
Cleaner production aims to increase overall efficiency and reduce risks to humans and the environment.
Cleaner production principles:
- Precaution: Reducing externalities through redesign of industrial systems of production and consumption that are currently material-intensive.
- Prevention: Making changes upstream in the system of production and consumption.
- Integration: Integrating across economic, social, and environmental boundaries to achieve efficiency.

Cleaner Production Techniques

Product modification: Changes in product design, and potentially its use system, to reduce environmental impacts.
Input substitution: Using alternative input materials as product raw material or production/consumption auxiliaries to reduce environmental impacts.
Technology modifications: Changes in production facilities to reduce environmental impacts of production processes.
Good housekeeping: Changes in operating and maintenance procedures, management, and information systems to reduce leaks, spills, and left-overs.
