Company Background<br />
Reasons For Recycling Activities<br />
Examples And Results<br />
<strong>Loser</strong> <strong>Chemie</strong> GmbH, Germany
Company Background<br />
Our main business is<br />
the recyling of water<br />
• Founded in 2004<br />
• 45 employees<br />
• 3 production sites
Company Profile<br />
3 units <strong>with</strong> different alignments:<br />
business unit 1<br />
headquarters Hainichen:<br />
administration, r&d,<br />
analytics, facilities,<br />
environment, projects<br />
water<br />
chemistry<br />
business unit 2<br />
prodution site Langenbach:<br />
chemistry of aluminium<br />
and barium<br />
business unit 3<br />
production site Zwickau:<br />
chemical auxiliaries <strong>for</strong><br />
textile, paper and leather industry
Locations of our production sites in Saxony<br />
Hainichen<br />
since 2004<br />
Dresden<br />
Chemnitz<br />
Zwickau<br />
since 2007<br />
Langenweißbach<br />
since 2005
Tasks and Competences<br />
o LC produces special chemicals, e.g. <strong>for</strong><br />
removal of radium <strong>from</strong> mining water.<br />
o The poduction site in Langenbach has a<br />
capacity of 6600 tons/year <strong>for</strong><br />
polyaluminiumchlorides and 25000 tons/year<br />
<strong>for</strong> aluminiumsulfate as solutions.<br />
o Our reactions are conducted under pressure<br />
(6 bar) and high temperatures (160°C) <strong>with</strong><br />
concentrated inorganic acids.<br />
o LC produces about 500 auxiliaries <strong>for</strong> paper,<br />
textile, leather, drinking water and waste water<br />
industries all over the world.
Tasks and Competences<br />
o R&D laboratories: analytic promtly<br />
o development of new products and processes accordingly requirements of our<br />
customers<br />
o joint development projects<br />
o development and optimization of processes <strong>for</strong> own business activties (alternative<br />
raw materials and recycling)
Alternative Raw Materials and Recycling? Our Story:<br />
The problem: price <strong>for</strong> commodities rised<br />
The challenge: substitution of our raw materials<br />
The solution: use of alternative raw materials (waste?) and recycling <strong>strategies</strong><br />
Metals Price<br />
Index
Alternative raw materials? Aluminium <strong>for</strong> water treatment !<br />
aluminiumhydate + inorganic acids<br />
aluminiumsalts + water<br />
<strong>for</strong> example:<br />
chlorides, sulfate,<br />
nitrate, <strong>for</strong>miate<br />
replaceable ?<br />
Yes !<br />
useful<br />
Al-salts<br />
<strong>for</strong> water<br />
treatment<br />
and water<br />
recycling
PV Si-waste as Al source?<br />
metal removal <strong>from</strong> Si-cells<br />
Si-raw material<br />
… <strong>for</strong> working up and recirculation ?<br />
silver as silvernitrate solution<br />
<strong>from</strong> the back side of Si-Cells can be produced<br />
alkaline polyaluminiumchloride solution<br />
ingot
New focus: Recyclables<br />
• low-waste removal of <strong>metals</strong> <strong>from</strong> PV Si-cell-waste<br />
• production of alkaline polyaluminiumchlorides <strong>for</strong><br />
waste water treatment<br />
• patent announcement DE102007034441A1<br />
• recycling of CdTe, CIGS and CIS TF PV waste <strong>with</strong><br />
an universal treatment method<br />
• metalconcentrates possible, e.g. In(OH) 3<br />
• patent announcement DE102008058530A1<br />
• chemical treatment of fluorescent<br />
powder <strong>from</strong> recycling of lamps<br />
• removal of the rare earths<br />
• current works
