StyRedux® is a proven technology to mitigate styrene odors and
to reduce or eliminate potential environmental styrene contamination associated
with styrenated resin systems. Simply stated, StyRedux® converts residual styrene to an inert (non-hazardous) substance resolving
both the odor and contamination issues related to CIPP installations in the
field.
Significantly reduces styrene/volitile monomers in air and water process systems.
Significant savings compared to any other technology.

PolyThix(R):
A patented chemical thickener to reduce toxic spills to downstream environments.
PolyThix®, controls
viscosity of CIPP resin to eliminate drain-down, washout and resin slug. Improving production and quality by using a
lower viscosity at wet-out to significantly increase fiber saturation while
increasing production speeds 2-fold. Increasing
the viscosity of the resin after wet-out has multiple advantages: no pre-liner
required, consistent thickness, no-resin into the services (slugs), no
down-stream contamination and together with StyRedux®, the quality of the
installed product is superior.
Environmental and public concerns are eliminated producing a
consistently high quality product with the focus on “LESS DISRUPTION”.
The proceedures for operating under ASTM 1216, 5-15% excess resin to fill voids and for resin polymerization are in the majority of specifications. There is a need/requirement to keep the resin on the tube and in the confines of the host pipe (Consistent Thickness). A chemically thickened resin with PolyThix(R) will resolve any issue of drain-down, additives to the resin systems have tremendous success in controlling "drain-down" and "wash-out".
CIPP manufacturers rely on styrene to link polyester or vinyl ester molecules to form a large polymer chain that will provide properties to coat the inside of damaged pipes.
Other monomers substituted for styrene (double-bond carbon structure), i.e. Vinyl-Toluene (VT), DiAllyl Phthalate (DAP) are higher cost and lower in solubility of polyester/vinyl ester resin......performance is sacrificed.
With some certainty, we know how to control styrene and monomer toxic emissions to protect against health effects and production disruption, Styrene has advantages but will be a problem to workers exposed to it, the public smelling it and the environmental damage from it without controls.

Organizations Petition to Remove Authorization of Seven Synthetic Flavoring Food Additives
In the January 4, 2016, Federal Register¸ FDA announced notice of a petition by the Center for Science in the Public Interest, Natural Resources Defense Council, Center for Food Safety, and other organizations, proposing FDA amend the food additive regulations to no longer authorize the use of seven synthetic flavoring food additives and to establish zero tolerances for the additives. The seven food additives are: (i) benzophenone, (ii) ethyl acrylate, (iii) eugenyl methyl ether, (iv) myrcene, (v) pulegone, (vi) pyridine, and (vii) styrene. The petition provides new data establishing these substances are carcinogenic and therefore not safe for use in food.Comments are due March 4, 2016.
AIR EMISSIONS/WATER EMISSIONS
StyRedux® and PolyThix(R), have been
used on many projects throughout North America.
StyRedux® was developed to help manage complaints as well as avoid consequences from invasive toxic styrene fumes.

Boston and the
surrounding communities have benefited from StyRedux® use.
Boston College, Chestnut Hill campus, contractor used StyRedux® for a
liner under the ice rink.
2.)
Saugus Veterans Memorial Elementary School evacuated for the day due to a
lining project. StyRedux® was used for
the contractor to continue without incident.
3.)
Allston residence impacted in the early morning (4 am). StyRedux® used to finish the project while
EH&S monitored every parameter of the project without further impacts.
4.) Mitigation of styrene, Winchester Hospital, Winchester, MA
Winchester Hospital, Oncology Center requested no odor due to patient
care disruptions. Liner was situated 10
feet from door, no complaints and water was treated to less than 1 ppm as
directed by MWRA.
5.) Medford MA
project, siphon chamber manhole cover, terminal end of the liner, treated with
StyRedux®. Results were minimal releases
and non-disruptive during the whole process.
Monitored air and water, treated accordingly. Water/styrene concentrations were
non-detectable for final disposal.
SOLUTION TO ONGOING CIPP Emissions:
Control of Odors, Section 22a-174-23, Effective 4-04-2006
(a) (1) No person shall cause or permit the emission of any substance or combination of substances which create or contributes to an odor, in the ambient air, that constitutes a nuisance.
(2) An odor constitutes a nuisance if present with such intesity, characteristics, frequency and duration that
(A) It is, or can reasonably be expected to be, injurious to public health or welfare, or
(B) It unreasonably interferes with the enjoyment of life or the use of property, considering the character and degree of the injury to, or interference with, the health, general welfare, property of the people affected, and the location of the pollution source and character of the area or neighborhood affected. Whether the source of the emissions was present in the location first shall not be a consideration.
