(Presented by the Commission to the Council)
C0M(80) 831 final
Introduction
In implementation of the Action Programme of the,European Communities on the Environment of 20 December 1973, the Council adopted on 20 February 1978 (78/176/EEC) the Directive on waste from the titanium dioxide, industry, the aim of which is the prevention and progressive reduction, with a view to its elimination, of pollution caused by waste from the titanium dioxide industry. •
' ' ‘ • • ‘ . . . / •
' * . ■ . _ ' • ' : . ■ ,
The Directive stipulates the measures to be taken to achieve this end, in particular-, the prior authorizations for waste discharge issued by the competent authority of the Member State in whose territory the waste is produced and the drawing up of programmes
for the progressive reduction of pollution with a view to its
. ■ \ • '
ultimate elimination. .
Article 7 of the Directive also stipulates that the Commission will,
within one year of notification of the Directive, submit to the
. • . . / .
Council a proposal on the procedures for the surveillance and '
monitoring of the environments affected by waste from this industry. , ' .

The Commission has brought together a group of national experts to assist it in drafting the technical part of the Directive.
This group, which has met three times, has advised the Commission on the methods of surveillance and monitoring to be used and, in particular, on the list of the relevant parameters to be measured throughout the Community and on the minimum annual frequency of sampling with respect to the different environments receiving waste from the titanium dioxide industry.

2.2. Aims of the Directive
This Directive will - on the basis of the parameters selected -.provide the means of identifying pollution levels in those parts ‘ of the environment affected - from a physical/ chemical/ biological . and ecological! point of view.- by discharges of titanium dioxide ' waste/ of understanding pollution trends and of assessing the pro-
■ gressive reduction of pollution caused by these wastes. ,

3.1. £ijgm£n_^a_ry_p_ro£e_rt_i_es^ ‘ .. . •
In its erystaline form, titanium dioxide is currently regarded as having the highest refractory index of all the Conventional pig- > , ments in both its allotrophic forms/ i.e. anatase and rutile. As . a white pigment/ it is incomparable and irreplaceable. \
i. ’ • • . ’ • • 1 - . . , .' • • ’ • _ • . _ ' '
3.2. JJt^ljzjitj[on . ,, .
On account of its pigmentary properties this product has come .
. into widespread use in many areas/ principal among which are .
. paints and varnishes, paper, plastics, rubber, floor coverings, ceramics, andi synthetic fibres. The paint and varnish, industry accounts for more than half of the total consumption. .
3.3. Ti^ta£ijj7i_d_i_ox_id^e_m£njjf^ct_u_riing__pj^o_ce_ss^s_ , • * ■ \ . ,
. Manufacturing of titanium dioxide pigments consists in preparing -
high purity titanium dioxide from an ore in which it is present . ■
, already but mixed with other substances.. ^
There' is no industrial process for manufacturing titanium dioxide by which titanium dioxide can be extracted'selectively. The ^ only two existing industrial processes involve digestion of the
ore,followed by selective operations to. extract,the titanium compound.
. . ■ .. ■ ' - ■. * - ., . ' , .
In a final stage, the titanium dioxide is obtained from the intermediate compound. '
These two processes are known as the sulphate and chloride processes'respectively. ' , .
In the first process, the ore is opened up by sulphuric acid and then the titanium hydroxide is precipitated selectively. Finally, the titanium oxide is obtained by calcination of the hydroxide.
In the chloride process, the ore is chlorinated and the resultant titanium tetrachloride is first separated from the other chlorides mechanically and then distilled. Finally, the titanium oxide is obtained by oxidation of the titanium tetrachloride.
In Europe, the sulphate process is the one most commonly used.
3.3.1. _Su_lphate_p£Ojcess ’ ,
The ore used is either ilmenite or slag.
- Ilmenite is a mineral complex of titanium and iron containing on average 55% Ti(>2 and approximately 30% iron;
- slag is obtained from iron ore which contains some 70% Til^ . 10% iron as oxide plus metallic iron.
The main stages involved in the separation of TiO^ from other compounds are to dissolve nearly all the ore and then to precipitate the titanium selectively as hydroxide. This hydroxide is then calcined to give the titanium oxide.
- . . ' .
■ # ' ( ~ - '
'■ ' • : ; .• '■
The main waste products are:
(i) residue from the ore digestion process.
This insoluble residue is composed of unattached ore and insoluble silica;
(ii) ferrous sulphate in the form of heptahydrate (SO. Fe,7H-,0)
4 C
commonly known as 'copperas', resulting from the . reduction and crystalization of the solutions formed from the ilmenite digestion stage. This liquor is made , up of a complex salt of titanium, ferrous and ferric sulphate; .
. ’ \ ' •
(iii) mother liquor produced from the separation of titanium
gel after hydrolysis by filtration and/or decantation.
solution of ferrous sulphate contains the sulphates of amounts in the raw
This liquor is made up of a in sulphuric acid. It also the metals present in trace material;
(iv) various gel wash waters and waters from the scrubbing . of the calcination gases. They contain dilute sulphuric acid, traces of the salts of iron, titanium ancf other metals present in the ore. ,
3 .3.2. iJh_loHde_p£0_ces_s
The standard ore used in the chloride process is natural, rutile, a scarce ore very rich in TiC^ (approximately 96%), or alteran-tively concentrates generally obtained from ilmenite or synthetic
rutile. „
■ , ' ’ . ■ . , ■ ’ . . 1
The process consists in obtaining titanium tetrachloride from . the high-temperature chlorination of a rutile and carbon mixture. After condensation, purification and oxidation of the titanium
.../...
tetrachloride, the titanium dioxide is obtained; the regenerated '
I chlorine is recycled. .
, This process generates only small amounts of waste but is little , used in Europe^ But although this process uses concentrates of
ilmenite, it does involve an iron removal stage. This pretreatment leads to the same problems as those associated with waste from the sulphate .process.

3.4.1. In the sulphate process, the main wastes from the industry are:
insoluble substances, copperas, mother liquors or strong acids, wash waters or weak acids. ' >
, . • ‘ . i . • • f. . ' '
In the chloride process, the main process wastes are the chlorides . of manganese, magnesium, calcium, sodium, alumiqium, chromium, iron, vanadium, ZrO^, titanium dioxide, TiCl^ and chlorine.
‘ 1 ' ‘ ■ . * ’ 1 ‘ ‘ '
• • 1 . ' • ■ . ' .
3.4.2. The detailed composition of titanium dioxide manufacturing wastes varies according to the ores used, the manufacturing processes and the way in which the solid, liquid and gaseous wastes are treated at each stage of the process.
Liquid wastes . . ‘
Generally, these wastes have the /following features:
- high acidity;
- a high iron content, mainly in the form of iron sulphate
(0.8 to 14%); , : . ' '
, ■ ' . ’ ^ ■ ' V ' ’ • .
- suspended solids (oxides of Ti, Si, Fe, Al, Ca, Zr);
' . . ' ■ . ' •'•/•••*
- dissolved metals, normally in the following concentrations (in mg/l): ■
Mn: 400 to 1400; Cr: 4 to 225; Zb: 1 to 125; V: 75 to 110; Ni: 4 to 50; Cu: 0.1 to 10; Pb: 3 to 6; As: 0.04 to 4;
Cd: <£0.1; Hg: <£0.005.
Solid wastes
These are made up of copperas, arising from the processing of raw materials in the sulphate process and by the neutralized residues of ore or slag. Copperas contains^some 90% of iron sulphate present as FeSO^, TlF^O); the remaining fraction is made up of titanium dioxide, magnesium sulphate, free sulphuric acid and water of crystallization. The neutralised residues from the sulphate process contain ore or slag which is insoluble at 200°C in 90% sulphuric acid together with filter aids; the waste products from the chloride process comprise unattacked ores, coke and metal hydroxides.x ' . .
Gaseous waste
Principal among these are SO^ and S0^ which are formed from the residual sulphuric acid (100-120 kg per tonne TiO^) and the sulphur contained in the fuel used to initiate combustion when the hydrated titanium oxide is calcined. Depending on the conditions in which calcination takes place, the ratio of SO^: S0^ (calculated as F^SO^) ranges from 1:1.92 to 1:2.80. The amount of gaseous waste produced in the manufacture of one tonne of titanium dioxide ranges from 12 to 22.4 kg SOg and 53.6 to 60.2 kg S0j. .
Principal ‘methods of waste disposal used by the titanium
dioxide industry 1 ■■ -
The effects' on biotopes due to the various properties of the wastes are closely linked to the nature of the receiving medium. Sea waters are most frequently used for this, but in certain special circumstances the wastes may be discharged in fresh water, stored on land or injected underground into deep strata.
_ 1 • V /
Mscha£ges_at_ _sea_
The two principal methods of disposal are: ,
■ / ► * .
(i) by5 pipeline from the coast •
(ii) discharge at sea from special ships
' . • '
The first method normally requires prior.dilution of the effluent and a discharge point which favours rapid dispersal of the effluent. The acidic solutions are neutralized by dilution and by the buffer effect. . ,
The second method, namely discharge at sea, necessitates the use of specially-equipped tanker ships which enable the acid effluent to be discharged directly into the ship's wake, thus providing rapid dilution and conveyance of the effluent to greater depths. This method is used for soluble wastes (ferrous sulphate and acid solutions). . J
When titanium dioxide waste is discharged from a ship, the predominant short-term chemical impact is caused by the reduction in pH. According to the guidelines laid down by the Oslo Convention on discharges of titanium dioxide waste, the pH of the receiving waters must reach 6 within a maximum of 5 minutes after discharge. /
Since the pH of wastes varies according to their source and that different types of ship may be used (differences in size and speed), the following measurements should be taken before the permitted level of discharge is decided: .
(i) the pH at different dilutions of the receiving water should bfe calculated in such a way as to produce a pH/ dilution curve;
. ■ ■■' ... ■ ■ . , . • • . .
(ii) on the basis of this curve, if a pH of 6 or more must
- : be reached within 5 minutes, the requisite dilution
. ; \ ' ■ - r - ■ ,
v * can be calculated; - ; ■
(iii) -the. rate of discharge can be worked out depending on
the required dilution on the basis of experimental work " carried out on the ship itself' (using tracers) or by
calculation (using general formulae for the minimum . dilution in the ship's wake).
Another possibility is direct measurement of the pH of the waste • \ . . • . dissolved in the ship's wake during the discharge operation.
these conditions also presuppose that- the dilution engendered by ‘ the propeller,wake will be adequate to reduce the density . difference between the sea water/waste mixture and the receiving water to a sufficiently low level to prevent the formation of dense layers which would impede the subsequent mixing process.

This type of storage on 'tips' is used by small capacity titanium dioxide plants and is most frequently used for the small fraction of insoluble waste materials (i.e.'those which cannot

be dissolved by sulphuric acid when the ore is opened up).
. Furthermore, the acid effluent from this industry can be ;
neutralized by calcium carbonate and slaked lime (CaCOH^) and then' stored on land. The same is true for the ferrous sulphates. ,

, to sulphuric acid by the addition of sulphur.
Other potential outlets for these products have been contemplated, for example: iron oxi^e pigments, flux for the cement industry, weed killer and in water treatment for the production of drinking water. But only small quantities of copperas are ' . involved in these applications, ) , ' '
5. Methods of surveillance and monitoring of the environments affected
The methods for the survei llan.ce and monitoring of the environments receiving TiO., wastes discharged at sea or into fresh water, ,
' stored or dumped on land or injected into underground strata are based on the provisions of Annex II B of the Directive on waste
- 11
from the titanium dioxide industry, adopted by the Council on 20 February 1978 (78/176/EEC). , .
Where the waste is discharged into fresh water or dumped/ immersed at sea,, the following three .components shall be monitored: the water column,, living organisms and the sediment. Periodic checks on the state of the area affected by the discharges will make it possible to monitor changes in the environments affected.'
' • ^ - ' ' ' • , v
' A* ,
Monitoring of the .following parameters shall be compulsory:
(a) In the water column .
— pH, the salinity of sea .water,, -dissolved oxygen, turbidity,
, hydrated iron oxides and -hydroxides in suspension,
concentration of dissolved salts, toxic metals;
.Ob) In suspended solids and in sediment
— hydrated iron oxides and hydroxides and toxic metals;
Cc) In living organisms (having due regard to the species typical
of the discharge zone) : .
— the levels of iron, titanturn, chromium, cadmium, mercury, vanadium, nickel, copper, .zinc and lead;
(d) flora and fauna . , . ■ .
'diversity and relative abundance.
/ ...
• ' . , / ■ . .
V . ' . ■ h
Monitoring of the following parameters shall be optional:
• . \ . -
- - the level of chromium, vanadium, zinc, lead, nickel, .
copper, manganese in the water column and sediment and the
■ • - . . •
amounts of suspended solids. • '
5.2. In the case of storage, tipping or injection, the monitoring shall . include: • _ ■
- tests to'ensure that surface waters and ground waters have not been contaminated. These tests relate to a control of acidity, the levels of iron (dissolved and in suspension), calcium, chlorides, titanium and sulphates ancj to the . environment of the storage sites, i.e. the permeability, porosity, structure and stability of the soil,!i and to a
' • ■ " i. '
general ecological assessment of the area surrounding the tipping, storage or injection point. , .
6. . Sampling ,
The greatest attention should be paid to the taking of samples which should be regarded as a preliminary phase in the analysis process.
The methods of sampling should be such as to ensure that the conditions in which the measurements are taken can be reproduced and that the methods are representative of the conditions prevailing in the surrounding environment. Article 4(4) of this proposal for a directive lays down the general rules to be observed for sampling
Minimum annual frequency for sampling and for the analysis '
of parameters , ■, • ' .
’ • ' • / , . - * ■ 1 . ,
The frequency of sampling and analysis is the minimum number of
sampling operations and analyses to be carried out each year in respect of the various parameters described in the foregoing chapter and depending on the different environments affected by ■the discharge of waste from the titanium dioxide' industry. ■
The samples should be taken having due regard to local environ- -mental and discharge conditions, i.e* whether the discharges are intermittent or continuous, the exact Site of the sample taking and its distance from the discharge point should be specified in each case by the competent authority in each Member State.
Where the results of measurements taken on samples from the discharge zone are consistent or show a significant improvement in environmental quality over the previous year, the frequency of sampling and analysis may, with the prior agreement of the Commission, be reduced by the Member State concerned. .
• “ ■ • ' ■ " •. '5 ' , ' ' •' t
Accordingly, the Member States should communicate to the-Commission the results of these measurements and state the : frequency they propose to adopt. :
Preservation and transport of samples ' .'
As stated in Article 5, the type of container used for sampling and packaging should not influence the analytical results.
The volume of such sampling bottles should be such as to enable ' the specified measurements to be carried out in optimum conditions of reproducibility. Since the characteristics of the sample wafer may alter quite rapidly under the action of the various organisms it contains, such changes as may occur between the moment of .
sampling and analysis should be kept to a strict minimum by carrying out the analyses as rapidly as possible. ' .../...
-14-
Many investigations have been made with a view to recommending methods by which water samples can be stored without their composition being affected. But it is impossible to lay down any hard and fast rules which would cover every case and every situation and to which there would be no exceptions. The samples needed to measure the parameters should be transported to the laboratory for examination at the earliest opportunity. If immediate analysis is not possible, the samples should be kept under conditions where the containers are protected from any outside contamination and no change in the state of their contents is possible.
Methods of measurement , ' .
The reference methods of measurement for each parameter selected for the surveillance and monitoring of the environments affected' are shown in the Annexes to this proposal.
Laboratories in the Member States using other methods must ensure that the results obtained are equivalent or comparable to those given in the Annexes.
The result obtained from the samples and methods of measurement must be representative of the true average quality of the water analysed. The various operations needed to achieve this result . may lead to errors; it is vital that, such errors be detected and then eliminated or reduced.
The Annexes to this proposal for a Directive lay down the conditions in which the measurements of certain parameters must be carried out in view of the risk that their value may change during the transport or protracted storage of the water samples in containers. This is the case with temperature and pH.

Action at international and Community level -.
In the campaign against freshwater and sea water pollution, the Community is a Contracting Party to international conventions aimed at reducing and eventually eliminating this type of pollution. The conventions are: , ' .
“ The Convention for the Prevention of Marine Pollution from Land-based Sources (Paris Convention) (75/437/EEC);
f- 1 , ’ , . * • ‘ 1 -
Convention for the Protection of the Mediterranean Sea
. against Pollution (Barcelona Convention); ,

- Protocol for the Prevention of Pollution of the Mediterranean Sea by Dumping from Ships and Aircraft (77/585/EEC);
— Convention on the Protection of the Rhine against Chemical Pollution (77/585/EEC) .
On 17 May 1980, the Community also signed the Protocol on the protection of the Mediterranean Sea against pollution from Land-based sources. ,
Specific articles of these Conventions either ban the dumping or'
• . _ ' t' # . • ,
discharge of certain substances such as acid compounds whose .
‘ t c
composition and auqntity are such that they may adversely affect . the quality of sea water or make the dumping or discharge of
•• i 1
specific substances, such as titanium, chromium and acid compounds subject to the prior granting of a specific permit or to appropriate programmes and measurements to reduce pollution.
- 16
The Community participates as an observer in the Convention for the Prevention of Marine Pollution by Dumping from Ships and Aircraft, signed in Oslo on 15 February 1972. The Community is closely '
following the work being done under the auspices of the Standing Advisory Committee to the Scientific Councils of the Oslo 1
Convention and the Joint Working Party on monitoring and continuous surveillance under the Oslo and Paris Conventions; this work concerns the monitoring and continuous surveillance of the sea areas into, which titanium dioxide wastes are discharged. -

In January 1976, moreover; the Commission put forward a proposal for a Council Directive on the dumping of wastes at sea (OJ C 40,
20 February 1976) which contains a brief review of the legal situation regarding this method of dumping at sea. \
... - i ■■■’ . .. V . ■ -
. Finally, a Directive on pollution caused by certain dangerous 1
substances discharged into the aquatic environment of- the _
Community (76/464/EEC) stipulates that pr'ior authorization must be obtained for any discharge into waters likely to contain one of the substances specified in Annex II, such as titanium, zinc, vanadium, chromium etc. , ‘ ,
Consultation of the European Parliament and the Economic and
Social Committee ' .
'Since this proposal for a Directive1 is based on Article 7 of Directive 78/176/EEC, consultation of the European Parliament and of the Economic and Social Cbmmittee is obligatory, as stipulated in paragraph 3 of .this Article.
