Title: Industrial Ecology


1
Industrial Ecology
  • Lecture 13

2
Overview
  • Terminology
  • Design for the Environment
  • Natural Systems as Models
  • Directions in Industrial Ecology
  • Examples

3
Terminology
  • Ecology the study of the earths life support
    systems, of the interdependence of all beings on
    Earth (Odum, E.)
  • Metabolism sum of the processes sustaining the
    organism production of new cellular materials
    (anabolism) and degradation of other materials to
    produce energy (catabolism) (Ray)
  • Industrial Ecology application of ecological
    theory to industrial systems (Rejeski) views the
    industrial world as a natural system, embedded in
    local ecosystems and the local biosphere (Lowe)
  • Industrial Metabolism flow of materials energy
    through the industrial system and the interaction
    of these flows with global biogeochemical cycles
    (Erkman)
  • Industrial Symbiosis an industrial system where
    waste from processes is a resources for other
    processes

4
More Terminology
  • Eco-Efficiency Integration of economic
    efficiency (financial return, profit,
    productivity, customer perception) and
    environmental efficiency (energy, emissions,
    environmental impacts.
  • Ecofactory integrated design of production
    systems technology- including DFE at product and
    process levels with disassembling, reuse and
    materials recycling technology (Agency for
    Industrial Science and Technology, Japan)

5
More Terminology
  • Design for the Environment considers all
    potential environmental implications of a
    product energy and materials used in the
    product its manufacture and packaging
    transportation consumer use, reuse, and
    recycling and disposal.
  • DfX
  • Design for Recycling
  • Design for Disassembly
  • Design for Remanufacturing

Natural Systems
  • Function as an integrated whole
  • Minimize waste dead or alive all plants and
    animals and their wastes are food for something
  • Decomposers (microbes and other organisms)
    consume waste and are eaten by other creatures in
    the food chain
  • Toxins are not stored or transported in bulk but
    are synthesized and used as need by species
    individuals
  • Materials are continually circulated and
    transformed in elegant ways.
  • Nature runs largely off solar energy
  • Nature is dynamic and information driven,
    identity of ecosystem players is defined in
    process terms

10
The Industrial Ecology Paradigm
  • Earth is a closed ecological system the scale
    and design of development is inconsistent with
    long-term ecological survival
  • Human society and natural systems have co-evolved
  • Nature has intrinsic value, revealed thru
    economic activity
  • The ethical/moral underpinnings of economic
    actions omit concerns for the world
  • Sustainability (strong) means independently
    maintaining stocks of natural and human capital
  • Ecologize Economy, an economy based on service,
    not goods, or quantity, of life
  • Moral/ethical transformation to instill
    environmental concerns
  • Technological realism, precautionary principle
    for uncertainty

11
More about Industrial Ecology
  • Industry mimics nature
  • Waste from one organism is food for another
  • Everything is connected by cyclic processes
  • Living off natures interest
  • Shift in thinking
  • Past Remediation
  • Present Treatment, storage, and disposal
  • Future Industrial metabolism and the industrial
    ecosystem
  • Management of the nature-industry interface
  • Ultimate goal bringing the industrial system as
    close as possible to being a closed-loop system
    with near complete recycling of materials.
  • Is zero waste achievable, considering
    thermodynamics, or is zero environmental impact a
    more feasible target?

12
Framework for Industrial Ecology
  1. Improve metabolic pathways of industrial
    processes and systems
  2. Create loop-closing industrial systems
  3. Dematerialize industrial output
  4. Systematize patterns of energy use
  5. Balance industrial system input and output to
    ecosystem activity
  6. Align policy to conform with long-term industrial
    system evolution
  7. Create new action-coordinating structures,
    communicative linkages, and information

13
Industrial Metabolism
  • A Big Picture analytic tool developed by Robert
    Ayres
  • Examination of the total pattern of material and
    energy flows form initial extraction of resources
    to final disposal of wastes
  • Factors in the real value of nonrenewable
    resources and environmental pollution, gives
    value to externalities
  • Can be used for regions (the Rhine basin),
    specific industries (aluminum) or specific
    materials (heavy metals)
  • Suggests some measures of sustainability ratios
    of potential to actual recycled materials, virgin
    to recycled materials, materials productivity

14
Problem
  • On average, only 6 of resources taken from the
    environment end as products.
  • Other 94 is waste.

Source Lowe, Warren, Moran, 1999.
Is it really waste? Or is it a by-product that
can be used elsewhere?
15
Industrial Symbiosis
  • Most commonly understood meaning of industrial
    ecology
  • Waste materials and energy serving as inputs or
    resources for other industrial processes
  • Also referred to as By-product synergy, green
    twinning, zero-waste/zero-emissions,
    cradle-to-cradle eco-efficient manufacturing
  • Evolving into the concept of an Eco-Industrial
    Park where co-locating

Back to Industrial Ecology
  • The name industrial ecology- why?
  • Models of non-human biological systems and their
    interactions with nature are instructive for
    industrial systems that we design and operate
  • The biological model is clever, a closed-loop
    materials system
  • Recent better understanding of the materials and
    energy flows of biological systems
  • Questions
  • How do you apply the biological principles of
    resilience, limiting factors, other rules?
  • What about the low efficiency of natural systems
    (lt5)?
  • Bottom Line
  • Lessen (dramatically the impacts of our
    industrial system)
  • Management of the industry-natural systems
    interface, match input-output of the manmade
    world to the constraints of the biosphere

20
Implementing Industrial Ecology
  • Technical Basis
  • Choose material
  • Design the product
  • Recover the material
  • Monitor the Situation
  • Institutional Barriers and Incentives
  • Market and informational barriers
  • Business and Financial barriers
  • Regulatory barriers
  • Legal Barriers
  • Regional Strategies
  • Ecoparks, Eco-Factories

21
Candidates for Lessening Impacts
  • Zero Emissions Systems
  • Orderly progression from Type I (high throughput
    mass and energy, no resource recovery) to Type
    III (closed loop)
  • Eliminate leaks
  • Material Substitution
  • More durable, less waste, more recyclable
  • Dematerialization
  • Theory of Dematerialization the more affluent a
    society becomes, the mass of materials required
    diminishes over time
  • Must result in less waste to be effective
  • Functionality Economy
  • What is the function? Do we need automobiles?
    Waste from telephone disposal (old phones were
    leased and returned!)

22
Design for the Environment (DFE)
  • Considers all potential implications of a product
  • Energy materials
  • Manufacture packaging
  • Transportation
  • Consumer use, reuse or recycling, and disposal
  • A holistic design process
  • Example automobile bodies (Iron, plastics,
    aluminum)
  • Tradeoffs virgin vs. recycled, energy at each
    stage, materials recyclability,
    manufacturability, costs
  • Challenges
  • Adequate database about materials and their
    impacts
  • Concurrent engineering to work across RD,
    marketing, quality..
  • Public sector involvement for defining values for
    trade-off

24
The Eco-Industrial Park (EIP)
  • A community of manufacturing and service
    businesses seeking enhanced environmental and
    economic performance through collaborating in the
    management of environmental and resource issues.
  • The interactions among companies resemble the
    dynamics of a natural ecosystem where all
    materials are continually recycled.
  • Industrial Park restricted meaning in terms of
    geography and ownership.
  • An EIP is a relate estate property that must be
    managed to bring a competitive advantage to its
    owners.
  • An EIP is a community of companies that must
    manage itself to provide benefits for its
    members.
  • Decisions are based on maximizing the
    profitability of the EIP as a whole
  • Transfer prices negotiated so each member will be
    as profitable as without the EIP

25
Green Buildings and Ecology
  • A highly successful international Green Building
    movement exists and is rapidly progressing
  • Buy-in is occurring by the public and private
    sectors and market demand is increasing
  • New products and services supporting this
    movement are appearing daily
  • BUT..the design, construction, operation, and
    disposition of Green Buildings is not based in
    science and its connection to ecology is at best
    tenuous
  • The proponents of Green Building are architects,
    engineers, planners, and others with little or no
    education, training, or experience in ecology

26
Typical U.S. Green Building
  • Based on the application of the LEED (points)
    system
  • Energy efficient (first law) renewable energy
    sources
  • Water efficient reuse or rainwater harvesting
  • Recycled content or used building materials with
    low embodied energy certified wood local
    materials
  • Healthy interior air quality
  • Proximity to mass transit
  • Reduction in construction waste
  • Rationale Protect the environment and the
    functioning of ecosystems

of natural and recycled materials. 2. a home
combining passive solar architecture with thermal
mass construction. 3. renewable energy and
integrated water systems make the Earthship an
off-grid home with no utility bills. www.earthship

Problem-Ecological Insights
  • Rationale Knowledge of ecology is a prerequisite
    to creating green buildings, otherwise we are
    guessing and using pure intuition
  • Problem How do we use ecology to inform our
    design, construction, operation, and disposition
    of the built environment?
  • Spinoff Questions
  • Should the built environment behave like a
    natural system?
  • Energy Use
  • Materials Flows
  • Should we merely use the metaphor of a natural
    system?
  • How do we interface natural and human systems?
  • How do we redesign our industrial system to
    behave like an ecosystem?

Construction Ecology and Metabolism
  • Ecology and Industrial Ecology as the basis for
    sustainable construction or green building
  • Industrial Ecology has made significant progress
    in the past decade Industrial Symbiosis
  • Lessons from nature
  • Closed loop cycling of materials zero waste
  • Maximize 2nd Law efficiency (effectiveness) and
    then maximize 1st Law efficiency
  • Nature is adaptable, diverse, and resilient
  • Emergent systems functioning on the edge of chaos
  • A subset of construction ecology and metabolism
  • Radical sustainability for construction

40
Initial Conversations with Ecologists
  • Interface buildings with nature and model based
    on nature
  • Make buildings part of the geological landscape
  • Design buildings that are deconstructable with
    components that are reusable and ultimately
    recyclable
  • Make buildings adaptable, flexible for multiple
    uses
  • Integrate industrial and construction activities
    with ecosystem functions to sustain or increase
    the resilience of society and nature
  • Keep materials in productive use, implies keeping
    buildings in productive use
  • Use only renewable, biodegradable materials or
    their industrial equivalents such as recyclable
    industrial material

52
Conclusions
  • Natural systems hold the key, both as metaphors
    and actual examples, for truly green buildings
  • Ecologists must be integrated into this movement
    to gain their expertise on how natural systems
    behave
  • Construction Ecology is based on the integration
    of Ecology and Industrial Ecology
  • Construction Ecology is in fact a subset of
    Industrial Ecology
