Air Pollution and Toxic Hazards Associated with Poultry Litter Incineration

by Mike Ewall, Novem­ber 2007

What Goes In, Must Come Out

One of the most basic prin­ci­ples of incin­er­a­tion is that what goes in, must come out.  There is no alche­my going on, so if there are tox­ic heavy met­als like lead, mer­cury or arsenic going in one end, they must come out in the form of tox­ic ash and tox­ic air emis­sions.  When anoth­er class of con­t­a­m­i­nants known as halo­gens enters an incin­er­a­tor, you have anoth­er sit­u­a­tion on your hands.  These halo­gens (chlo­rine being the most promi­nent) are often released in the form of acid gas­es (con­tribut­ing to acid rain and res­pi­ra­to­ry prob­lems) and also are released in small vol­umes of extreme­ly tox­ic chem­i­cals called diox­ins and furans (among the most tox­ic chem­i­cals ever stud­ied).[1]

Nat­u­ral­ly, when eval­u­at­ing incin­er­a­tion, one of the first ques­tions becomes “what is going in to the incin­er­a­tor?” Incin­er­a­tion of poul­try waste bring much need­ed atten­tion to what is in poul­try waste and in the chick­en and turkey feed itself.

Arsenic Use in Chicken & Turkey Feed

Accord­ing to the Envi­ron­men­tal Pro­tec­tion Agency, “Organ­ic arsenic com­pounds are exten­sive­ly added to the feed of ani­mals (par­tic­u­lar­ly poul­try and swine) in the Unit­ed States to improve growth rates by con­trol­ling par­a­sitic dis­eases.”[2]  Sev­er­al oth­er arti­cles and gov­ern­ment reports con­firm this, includ­ing stud­ies by the U.S. Geo­log­i­cal Sur­vey look­ing into the land and water impacts of arsenic-con­tain­ing poul­try lit­ter being land applied in the Chesa­peake Bay water­shed, where they have found trace ele­ments of arsenic in Mary­land’s Pocomoke Riv­er.[3,4,5,6,7]

Rox­ar­sone, or 3‑ni­tro-4-hydrox­ypheny­lar­son­ic acid, is cur­rent­ly the most com­mon­ly used arseni­cal com­pound in poul­try feed in the Unit­ed States, with a usage of 23 to 45 grams of chem­i­cal per ton of feed for broil­er chick­ens for increased weight gain, feed effi­cien­cy, improved pig­men­ta­tion, and pre­ven­tion of par­a­sites.[3,8]  Rox­ar­sone is used in turkeys as well as chick­ens.[9]  By design, most of the chem­i­cal is excret­ed in the manure.[2,3,5]

Stud­ies have shown arsenic con­cen­tra­tions in poul­try lit­ter to be between 15 and 35 ppm (parts per mil­lion).[2,3,10]  At these con­cen­tra­tions, one can expect that the 300,000 tons per year of chick­en lit­ter than Fibrowatt plans to burn at their pro­posed Hur­lock, Mary­land and Magee, Mis­sis­sip­pi plants would con­tain 9,000 to 21,000 pounds (4.5 to 10.5 tons) of arsenic.  Fibrowat­t’s first and largest pro­pos­al in the U.S. — one for 500,000 tons per year of turkey waste in Ben­son, Min­neso­ta — would burn waste con­tain­ing 15,000 to 35,000 pounds (7.5 to 17.5 tons) of arsenic each year.

Even if pol­lu­tion con­trol equip­ment were able to remove 99% of this arsenic, that would leave 90–210 pounds (150–350 for Min­neso­ta) of arsenic air pol­lu­tants, mak­ing these incin­er­a­tors a major source of arsenic air pol­lu­tion.  The Fibrominn air per­mit projects that the Ben­son plant would emit 64 pounds a year of arsenic into the air, mean­ing that the plan­t’s pol­lu­tion con­trols would have to cap­ture between 99.6 and 99.8% of the arsenic.[11]  Any arsenic cap­tured in pol­lu­tion con­trols would not sim­ply dis­ap­pear, but would become part of the fly ash, which Fibrowatt plans to sell as fer­til­iz­er.[12,13,14,15]  This is a lose-lose propo­si­tion.  The low­er the air emis­sions (due to bet­ter pol­lu­tion con­trols), the more tox­ic the ash “fer­til­iz­er” will be.

Min­neso­ta state law sets an ambi­ent air lim­it stan­dard of 0.002 micro­grams per cubic meter for arsenic.  There is rea­son to believe that the “Fibrominn” incin­er­a­tor may vio­late Min­neso­ta’s Chron­ic Health Risk Val­ue for arsenic and arsenic com­pounds, which ought to be mea­sured at Fibromin­n’s prop­er­ty line.[16]

State reg­u­la­tors in Min­neso­ta, where the first poul­try waste incin­er­a­tor in the U.S. is planned, are rely­ing on self-report­ed data from one of Fibrowat­t’s 3 exist­ing facil­i­ties (all of which are in the UK), con­clud­ing that arsenic won’t be a major con­cern at the pro­posed Fibrominn plant.[17]  How­ev­er, one of the oth­er two Fibrowatt plants in the UK (Fibro­gen in North Lin­colnshire) is list­ed as the 27th largest arsenic air emit­ter out of the 93 list­ed in the 1998 Pol­lu­tion Inven­to­ry of Indus­tri­al Units in Eng­land and Wales.[18]

It is being assumed that emis­sions from a poul­try waste burn­er in the U.S. would be com­pa­ra­ble to the British facil­i­ties, even though no effort has been made to eval­u­ate whether arseni­cal and oth­er feed amend­ments are used as wide­ly in the British poul­try indus­try as in the U.S.  Until this is known, extrap­o­la­tions of emis­sions from Fibrowat­t’s UK facil­i­ties to those in the U.S. are inappropriate.

Arsenic is more tox­ic than lead and has been the sub­ject of much polit­i­cal debate after much sci­en­tif­ic research led pol­i­cy­mak­ers to seek to low­er the allow­able amount of arsenic in drink­ing water.[19,20]  Arsenic’s use in wood-treat­ment chem­i­cals has been phased out.[21] Arsenic is clas­si­fied as a known human car­cino­gen and, when inhaled, can cause can­cer in humans, par­tic­u­lar­ly lung can­cer.[10,22,23,24]  A new study sug­gests that arsenic inter­feres with hor­mones, mak­ing it a potent endocrine dis­rupter.[25]

Dirtier than Coal Plants

The air pol­lu­tion per­mit for the pro­posed Fibrominn project allows that incin­er­a­tor to emit near­ly 5 mil­lion pounds of reg­u­lat­ed air pol­lu­tants each year, includ­ing 388,000 pounds of sul­fu­ric acid, 236,000 pounds of hydrochlo­ric acid and 4,600 pounds of hydro­flu­o­ric acid.[26]  That’s about 1,722 pounds a day of acid gas­es released into the sky above Ben­son, Min­neso­ta.  The per­mit states that “the pro­posed source will be a major source for haz­ardous air pol­lu­tants.” This is a gross under­state­ment.  It would not only be “a major source” — if near­ing their per­mit lim­its, the incin­er­a­tor would be the largest source of sul­fu­ric acid in Min­neso­ta (exceed­ing the COMBINED emis­sions of all of the coal-fired pow­er plants and oth­er sources in the state which report­ed their tox­ic releas­es to the U.S. EPA’s Tox­ic Release Inven­to­ry data­base in 2000).  It would also be the sec­ond largest source of hydrochlo­ric acid air pol­lu­tion in the state, beat­ing out the state’s paper mills, an oil refin­ery and all but one of the state’s coal-fired pow­er plants.[27]

Fibrowatt would argue that their actu­al emis­sions would be nowhere near their per­mit lim­its and that it would be improp­er to com­pare their per­mit lim­its with actu­al (self-report­ed) emis­sions from oth­er indus­tries. Were this true, it begs the ques­tion: why would Fibrowatt need per­mit lim­its far, far high­er than what they expect to release?

To make a fair com­par­i­son, it would be best to com­pare actu­al emis­sions to actu­al emis­sions, or per­mit lim­its to per­mit limits.

The Blue Ridge Envi­ron­men­tal Defense League (BREDL) — a region­al grass­roots envi­ron­men­tal net­work based in North Car­oli­na — is fight­ing Fibrowat­t’s plans to build three poul­try waste incin­er­a­tors in North Car­oli­na. They com­pared the per­mit­ted emis­sions from Fibrowat­t’s Min­neso­ta plant to the per­mit­ted emis­sions of a new coal pow­er plant planned in North Car­oli­na. The com­par­i­son shows that Fibrowat­t’s per­mit lim­its are high­er for four of the five major reg­u­lat­ed air pol­lu­tants reg­u­lat­ed in these per­mits. Emis­sions of nitro­gen oxides (NOx) and acid gas­es (hydrochlo­ric and sul­fu­ric acids) would be 2–3 times high­er from Fibrowatt (129% and 162% increas­es, respec­tive­ly). Emis­sions of par­tic­u­late mat­ter would be 33% and car­bon monox­ide would be 60% high­er. The sul­fur diox­ide emis­sions would be 53% low­er.[28]

In Novem­ber 2007, Fibrowatt coun­tered this com­par­i­son, argu­ing that they would­n’t be as pol­lut­ing as a coal plant. They did their own com­par­i­son — com­par­ing actu­al emis­sions from the just-opened Fibrominn plant to exist­ing coal pow­er plants in North Car­oli­na.[29] While a com­par­i­son of actu­al emis­sions would nat­u­ral­ly be best, Fibrowat­t’s com­par­i­son is a false one. They com­pared their incin­er­a­tor to coal pow­er plants that were built decades ago, which would be ille­gal to build today, with­out being sub­ject­ed to much more strin­gent air pol­lu­tion laws. As it turns out, BREDL’s com­par­i­son is more accu­rate, as it com­pares “apples to apples” by look­ing at recent per­mits under mod­ern-day air pol­lu­tion laws.

When Fibrowatt was asked whether they could meet the cur­rent lim­it for nitro­gen oxide emis­sions that the Cliff­side coal pow­er plant pro­posed in North Car­oli­na would have to meet, they respond­ed that they could not. An envi­ron­men­tal engi­neer in the North Car­oli­na Divi­sion of Air Qual­i­ty affirmed, in a 2006 arti­cle in the Char­lotte Observ­er, that Fibrowat­t’s “emis­sions would be sim­i­lar to those of reg­u­lar coal-fired pow­er plants.”[30]

Chlorine Contamination and Dioxin

Diox­in was declared a Class 1 car­cino­gen, or “known human car­cino­gen,” by the Inter­na­tion­al Agency for Research on Can­cer (IARC), an arm of the World Health Orga­ni­za­tion, in Feb­ru­ary, 1997.[31]  This was con­firmed by the U.S. Nation­al Tox­i­col­o­gy Pro­gram in their Ninth Report On Car­cino­gens.[32]  In 2001, Bush’s EPA signed an inter­na­tion­al agree­ment seek­ing to elim­i­nate sources of diox­in.[33]  Diox­in is formed acci­den­tal­ly in the course of most incin­er­a­tion process­es and in cer­tain oth­er indus­tries where chlo­rine is used.  Incin­er­a­tors are the largest known source of diox­in.[34]

Diox­in would­n’t be much of an issue if the ingre­di­ents for form­ing diox­in weren’t being placed in the incin­er­a­tor.  Diox­in pro­duc­tion requires hydro­car­bons and chlo­rine.  Poul­try lit­ter is full of hydro­car­bons, both in the manure and the bed­ding.  There should be no short­age of chlo­rine in the poul­try lit­ter, either.  This is appar­ent from the huge amount of hydrochlo­ric acid that the Fibrominn incin­er­a­tor would be per­mit­ted to release.

One of the sources of chlo­rine is from the var­i­ous drugs and pes­ti­cides used in the poul­try indus­try.[35]  Chlorte­tra­cy­cline is a chlo­ri­nat­ed growth-pro­mot­ing antibi­ot­ic wide­ly-used in the broil­er indus­try.  Also, at least sev­en oth­er drugs, most of them antic­oc­cidi­als are chlo­ri­nat­ed.[36]  One of the more com­mon­ly used antic­oc­cidi­als is Ampro­li­um.  The residues in poul­try lit­ter of Chlorte­tra­cy­cline and Ampro­li­um alone rivals that of Rox­ar­sone, the most com­mon arseni­cal.[37]  With this many tons of chlo­ri­nat­ed drug residue in poul­try lit­ter, there is undoubt­ed­ly an ample sup­ply of chlo­rine for diox­in for­ma­tion.  After all, diox­ins are typ­i­cal­ly mea­sured in nanograms and picograms, since they are tox­ic in such tiny amounts.

Copper, Iron and Zinc Boost Dioxin Formation

Poul­try are treat­ed with cop­per sul­fate to avoid a com­mon dis­ease called “aspergillo­sis.” Evi­dence from chick­en lit­ter in Arkansas shows near­ly twice as much cop­per as arsenic in poul­try manure.[10]  In fact, cop­per lev­els in chick­en lit­ter as high enough that cat­tle have died from cop­per poi­son­ing from being fed chick­en lit­ter.[38]  Iron and zinc are also used as feed addi­tives.[35]  They are found in even high­er lev­els in poul­try manure than arsenic and cop­per.  Arkansas chick­en manure con­tains 11 times as much iron as arsenic and 12 times as much zinc.[10]  Fibrowat­t’s exist­ing poul­try waste incin­er­a­tors in the UK pro­duce ash which, accord­ing to Fibrowat­t’s own data, con­tains sig­nif­i­cant amounts of cop­per, iron and zinc.[15]

Cop­per, iron and zinc are a par­tic­u­lar haz­ard when placed in an incin­er­a­tor, since they serve as cat­a­lysts for diox­in for­ma­tion.[39]   This means that these met­als will cre­ate a sur­face for diox­ins — the most tox­ic chem­i­cals known to sci­ence — to form out of the hydro­car­bons and chlo­rine in the burn­er.  While cop­per is the most effec­tive cat­a­lyst, iron and zinc are also quite effec­tive at boost­ing diox­in production.

Although poul­try waste incin­er­a­tion is tout­ed as “renew­able bio­mass” and “green ener­gy,” the diox­in pol­lu­tion lev­els being grant­ed for the Fibrominn incin­er­a­tor are com­pa­ra­ble to diox­in emis­sions from munic­i­pal sol­id waste (MSW) incin­er­a­tors cur­rent­ly oper­at­ing in the U.S.  MSW incin­er­a­tors are — cat­e­gor­i­cal­ly — the coun­try’s largest known source of diox­in emissions.

Choose Your Own Permit

The per­mit has a “fill in the blanks” style emis­sions lim­it for fine par­tic­u­late mat­ter, where no lim­it is set by the agency and Fibrowatt gets to build and oper­ate the incin­er­a­tor for a while, then do some test­ing and pro­pose what they think the lim­it should be, based on what they can man­age to meet, rather than set­ting lim­its based on what would be con­sid­ered an “accept­able” amount of pol­lu­tion that would­n’t harm the health of humans and oth­er liv­ing sys­tems. Page A‑7 of their air pol­lu­tion per­mit states that:

Par­tic­u­late Mat­ter less than 10 micron: less than or equal to < > lb/mmBtu, based on three runs that are between 60 and 120 min­utes in length. The Per­mit­tee shall pro­pose lim­its after com­ple­tion of the Per­for­mance Tests required below. [40]

Lack of Monitoring

The Fibrominn incin­er­a­tor is only required to use con­tin­u­ous emis­sions mon­i­tor­ing sys­tems for nitro­gen oxides (NOx), car­bon monox­ide, sul­fur diox­ide (SO2), oxy­gen and opac­i­ty. Not a sin­gle tox­ic pol­lu­tant will be mon­i­tored on a reg­u­lar basis. Diox­ins and furans will be test­ed only once. Hydrochlo­ric acid, mer­cury and fine par­tic­u­late mat­ter (that under ten microns in size — called PM10) will be test­ed only 5 times, over the course of the first 15 months of oper­a­tion and none there­after. Oth­er pol­lu­tants that nev­er have to be mon­i­tored include ammo­nia, sul­fu­ric acid, hydro­flu­o­ric acid, poly­cyclic aro­mat­ic hydro­car­bons, volatile organ­ic com­pounds and tox­ic met­als (includ­ing arsenic).

Any claims of emis­sions being “clean” or “safe” need to be under­stood in the con­text that no one real­ly knows what’s being emit­ted since test­ing isn’t being done for most of the tox­ic and haz­ardous pol­lu­tants. Con­tin­u­ous emis­sions mon­i­tor­ing tech­nol­o­gy exists for all of the above-men­tioned pol­lu­tants, but state agen­cies aren’t in the habit of requir­ing their use, and com­pa­nies have no inter­est in obtain­ing data on their emis­sions if they’re not forced to.[41]
