Utilization of 
  waste materials, water, and energy for production should be sought to establish 
  symbiotic systems. However, conjugation of two or more independent industrial 
  material cycles are rather difficult (if at all possible) because of several 
  barriers inherent in a private enterprise system, not unless technical and policy 
  interventions, is adopted by the government.
These barriers 
  have been identified as follows:
  - Technical hurdles to the suitability 
    of the material for an intended reuse. Waste and product materials sometimes 
    contain unwanted elements that would ruin them for reuse or make them difficult 
    or dangerous to handle.
 
  - High cost of recycling compared 
    with costs of new materials. There are costs involved in recycling which include 
    costs of, transport, collecting information, energy and technology. These 
    costs have to be compared with costs of new materials as well as cost of disposal 
    into the environment.
 
  - Information barriers. In the 
    transfer and use of resources deemed valuable within an industrial ecosystem 
    such as excess production inputs (raw materials),waste and scrap materials, 
    energy (excess steam, heat, gas, power) Water (waste water and other liquid 
    inputs) and common facilities (other facilities with operational capacities 
    that need to be maximized), information is needed as to who might use these 
    disposables and who might have them available. These information are often 
    not available especially in sectors without traditional recycling networks.
 
 
   
     
       
         
           
             
               
                 
              
            
          
        
      
    
  
  - Organizational obstacles. 
    At the firm level, the present organization of a firm can be difficult to 
    change so that changing the whole concept of a product or adding new criteria 
    for environmental compatibility to the design process may not fit the ideas 
    on which the firm operates or its 'internal' incentive system.

Institutional 
      barriers. There is a need for government to affirm its commitment to industrial 
      symbiosis, and for its agencies (specifically DTI, BOI, PEZA, NEDA, DENR 
      and LGUs) to review existing status, plans, and policies to direct them 
      towards helping resolve the defined barriers. The current combination of 
      institutional mandate, available market-based incentives (both fiscal and 
      regulatory relief) and the capability & technical capacity are still 
      not conducive to support industrial symbiosis. Private firms would not immediately 
      embrace and apply the concepts of industrial symbiosis without the assurance 
      of incentives or at least support from the government to minimize or compensate 
      for the cost involved in the process. Further, the government through its 
      proper agencies would have to develop policies that will encourage industries 
      with high potentials for industrial symbiosis to locate in the same industrial 
      site or growth center.
   
 
General objective:
To evaluate how 
  the current policies support industrial ecology and propose policy recommendations 
  that would incorporate industrial ecology in the development and operation of 
  the country's industrial estates/ecozones and growth centers. Through further 
  policy formulation, implementing agencies must be able to clearly define its 
  role and actions to address specific barriers and encourage the implementation 
  of industrial ecology in general.
Specific objectives:
  - review and analyze existing 
    status/plans/policies and guidelines of the government on industrial growth 
    areas, specifically those on incentive and regulatory systems towards strengthening 
    of environmental management. A review of policies in neighboring countries 
    in Asia can be used as a basis of comparison to aid in policy analysis
 
  - define the environmental, 
    social and economic benefits which can be possibly be derived from incorporation 
    of industrial symbiosis and its advantages over other/existing ecozone management 
    strategies;
 
  - rationalize the possibility 
    of incorporating industrial symbiosis in each of the country’s ecozones or 
    growth centers by prescribing ways which material flows in each could be closed-looped
