Sustainable Industrial Design and Waste Management

implementing these techniques has to do more with attitudes and management
approaches rather than capital investment and technology. However, for the
second premise, which is that the techniques are false or infeasible, the struc-
tured implementation approach showed the feasibility and practicality of the
proposed techniques.
At this point management commitment is needed to convert the pro-
visional feasibility study prepared by the auditing team along with these rec-
ommendations into a detailed study that accounts for total budget and time
required to implement these techniques on a prototype scale.

Outcomes
Factory outcome
Misr Dairy while implementing the proposed clean production technique of
recovering the whey was able to make the following benefits and achievements:

• Recovery of more than 6,000 tons of byproducts that have a nutri-
tional value of $12/ton at a low capital investment.
• Elimination of environmentally polluted water of BOD (415 tons),
COD (522 tons), TSS (58 tons), TDS (218 tons) and oil/grease (60 tons)
per year.
• Elimination of the capital cost needed in the end-of-pipe treatment.
• Up to 25% reduction in wastewater disposal.

Farms’ outcome
The animal farms that carried out the proposed clean production technique
of changing the input material from water to whey obtained the following
results:

• Input material change through substituting water with high protein
and energy value whey.
• 100% saving in water consumption.
• 75% saving in dry feed consumption.
• Reduction of manpower and equipment cost associated with dry feed.
• Improvement in feed palatability, texture, and dust control of feedlot
rations.
• Increase in the safety factor of providing poor or variable quality diets.
• Provision of an economic and convenient method to feed urea supple-
ments, vitamins, minerals, and feed additives.

Sustainability
From the above discussion, it is clear that implementing these two simple
techniques will reduce waste disposal, reduce raw material cost, reduce pol-
lution damage cost, improve the farm’s performance, increase competitiveness
