ZERO
IMPACT MANUFACTURING INITIATIVE (ZIMI)
Zero
Impact Manufacturing Initiative (ZIMI) is an innovative
concept designed to mitigate the adverse environmental impact
of industry or other developmental activity through
introduction of clean technologies and practices skillfully
integrating the innovative zero emission approach with zero
consumption of prime or non-renewable resources. The concept
has been developed by Dr. Ashok Sharma of Cleantech
International Foundation who simulated a series of innovative
clean technology modules for a wide variety of polluting
industry as environmentally viable alternatives to prevailing
products, processes and materials leading to measurable
emission cuts, energy and material savings, toxicity
avoidance, hazard mitigation and reduced freshwater
consumption. The modules developed were field tested as
effective, versatile and globally replicable with potential to
reduce the overall environmental impact of the activity in
question facilitating environmental management beyond
compliance with assured payback. Examples include zero
emission in electroplating, textile dyeing, food
processing, metallurgy, metal fabrication and herbal
extraction apart from low energy processing in textile, powder
drying, fruit juice concentration and plywood industry. In a
significant development, virtual
waterless manufacturing modules were simulated for the
sugar, dairy, fruit processing and textile industry, featuring
zero freshwater intake together with zero wastewater
discharge. Finally a combination of measures like zero
emission with zero energy, zero freshwater
and zero prime materials
intake could demonstrably achieve zero environmental impact of
activities and facilities. The technologies demonstrated range
from simple separation and recycling technologies through
intermediate techniques like membrane technology, ozonation,
freeze drying, freeze concentration & micro-wave
technology to emerging techniques like laser, e-beam and
supercritical extraction. Bio technology, catalysis,
exothermic, endothermic and low temperature processing have
also been gainfully deployed. Precise process controls,
simulation and flow-analysis are deployed as additional
measures of impact mitigation. ZIMI
is universally applicable to all sectors of industrial,
developmental and human activities and holds potential to
eliminate pressure on global resources as well as the landfill
sites with an assured payback and holds promise to reduce the
total environmental impact of industrial activity to almost a
third, assuring a proportionate reduction in global emission
of greenhouse gases.
The
spectrum of industries exposed to scanner and consequent
re-engineering for zero impact treatment includes a diverse
range of processes including metallurgy, food processing,
sugar, paper, dairy, chemicals & petrochemicals, textile
processing, foundry, heat treatment, surface coating,
industrial drying, refrigeration, evaporation and other basic
energy intensive processes. Measures applied range from low or
no investment to total revamping of processes usually assuring
a payback of less than two years. The techniques applied go
beyond the normal conservation practices that are quite
familiar to industry to rethink the entire manufacturing
process in terms of viable alternatives placing lower demands
on energy along with other inputs like water and other raw
materials for total impact reduction on global environment.
