Special
Wastes
  We
typically deal with several types of solid wastes
that are considered "special." These wastes
include: health care wastes, construction and demolition
debris, oily sludges, residues from natural disasters,
and others. Management of each of these wastes requires
special expertise and understanding of the implications
related to the selection of one alternative versus
another one. Members of our company have acquired
the expertise to deal with these wastes as well as
others through basic research and actual implementation.
| Health
Care Wastes -- Members of the firm have
assisted national and international entities in
various aspects of the management process for
health care wastes. Work conducted has included:
development strategies for the adequate management
of expired pharmaceutical products, characterization
of the various wastes generated in typical health
care facilities, determination of physical and
chemical properties of the waste components, preparation
of tender documents, evaluation of waste management
practices, preparation of action plans, training,
and performance testing of low-cost combustion
units. Projects have been carried out in Ecuador,
India, Philippines, South Africa, and Geneva for
municipalities, ministries, and the World Health
Organization. |
| City
of San Jose, California -- Assistance
was provided to the City in the development of
a process to certify businesses that recycle or
reuse construction and demolition (C&D) debris.
An inventory of existing facilities was conducted.
A methodology for certifying the diversion rate
of each category of facility was developed and
tested. Field audits were performed, during which
operations were observed and records were reviewed. |
| U.S.
EPA -- The technical, economic, and environmental
feasibility of utilizing composting for treating,
detoxifying, and biostabilizing organic petroleum
wastes was investigated. Refinery oily wastes
were subjected to the compost process in a reactor
unit in order to ascertain the degree of degradation
of oil and grease. An analysis of the economic
and potential environmental impacts of oily waste
composting was performed. |
| Private
Client -- The effect of household
chemical products (HCPs) on municipal solid waste
landfills was evaluated. The overall project consisted
of two parallel activities: 1) the estimation
of the concentrations of HCPs entering landfills,
and 2) the conduct of laboratory-scale tests to
determine the impact of HCPs on the anaerobic
process that characterizes the landfill environment
for the majority of the life of the fill. |
