Socially-inclusive water efficiency & waste management

CIRCULAR ECONOMY BY DESIGN

Dr Kemi Adeyeye

• Assoc. Prof in Integrated Design

Lead, Water Efficiency Network Department of Architecture and Civil Engineering

Research focus:

• 5Ps: people, process,

performance, policy, products

• Socio-technical studies to

mitigate environmental impact and change

• Integrated design and

solutions for resource efficiency and resilience (RE+R)

Water is a vital human and natural resource It is also a scarce resource and this poses challenges for the 21st century and beyond

• Market for water supply, sanitation and water efficiency estimated at US$ 253bn and is

expected to grow to US$ 658bn by 2020

• Estimated investment of US$ 15bn per annum

Water Efficiency & Waste recovery

• Social-technical, multi-stakeholder

studies

• Process efficiency, optimisation
• Project examples: service innovation in

supply networks, resource efficiency in domestic and commercial sectors: e.g. laundrettes, hotels

“Water efficiency is not just about conserving water Instead, an understanding of customer behaviour and need is realised such that water is used optimally and through behaviour, technology and infrastructure efficiency, waste is eliminated”.

Decentralised/ alternative water supply

• Alternative water supply systems and

solutions can help to save water, energy, and money

• They are an essential component of a

circular economy for water and can help to address social challenges too

• Examples of non-potable (not for

drinking) use include:

• Agriculture and landscape irrigation
• cooling water in building services and

industrial applications

• construction activities e.g. concrete

mixing

• Domestic uses e.g. toilet flushing

Common technologies:

• rainwater recycling
• greywater reuse
• seawater desalination and;
• integrated sustainable urban drainage

Current work and circular economy

• Integrated social-environmental

studies on:

• Integrated solutions for water-

energy-(food?)

• Service innovation – socially

inclusive, optimised processes, reduced waste

Demand & Supply

Service innovation

People-centred Natural and built environment Resilience

Product innovation Efficiency processes

Lack of planning can lead to wasteful response, and breakdown of good practise. Resilience should be part of a circular economy

Main findings from previous research

• Resources/materials/products are not just

commodities, they have social (livelihood, quality of life) and environmental impact

• People should be at the core of circular economy policy

and practices

• Everything is connected –so opportunities for:
• Value creation – local, regional, global
• Resource efficiency and reduced waste (materials,

processes etc.)

• Information is key
• Integration/Joined up thinking helps to identify
• pportunities for value creation and waste minimisation

Collaboration

• Circular economy through water efficiency, reuse and recycling

(WASH)

• Circular economy (for resilience) in (informal) urban settlements
• Integrated water-energy cradle to grave solutions
• Energy recovery and reuse measures especially from water processes
• Combined value creation for waste minimisation and resilience
• Participatory, co-created design and implementation of solutions

(collaborative value creation)

• Improving adaptive capacity (e.g. through education and training) for

better use practices and waste reduction in processes
