	October 7, 2022 - The Glencore 
	Portovesme dispute remains open. Waiting for the new government to arrive 
	and the energy issue to be resolved. In addition to the proposal of a 
	bilateral agreement to restart production. 
	In the field, the company that confirms the 
	Cig but also leaves a door open to new projects and the trade unions which, 
	while reiterating their opposition to social safety nets, are asking for a 
	government commitment. The meeting at Mise to address the issue relating to 
	the future of Glencore Portoesme, the metallurgical company that between 
	Portovesme and Villacidro deals with the production of lead, zinc, sulfuric 
	acid, gold, silver and copper, is updated on when the new one will take 
	office. government. 
	During the 
	meeting at the Mise between the representatives of Glencore Portovesme, the 
	representatives of the Mite, the Region and the trade unions, the company 
	(which today, due to the high costs of energy, has slowed down production 
	and sent 400 workers to Cig) confirmed the intention to stop the lead line 
	and make use of social safety nets for another 200 employees. A decision 
	motivated by the fact that the Energy release measure does not meet one’s 
	needs and the cost of energy continues to rise. And it is always the 
	question of energy that determines the future of the plant that the 
	representatives of the Region have defined as strategic. 
	On the horizon, in fact, there is a relaunch plan that should go 
	through a reconditioning of the plants to arrive at the production of 
	materials useful for the “construction of new generation batteries”.
	 This would allow Glencore to become 
	the leading company in Europe, benefiting from consolidated plants and an 
	experienced, mature and specialized workforce – is the underlining of the 
	representatives of the regional council Alessandra Zedda, Anita Pili and 
	Gianni Lampis after the summit -. During the production transition phase, 
	the Region made itself available to invest in the training of workers. 
	The trade unions, which are now 
	awaiting the actions of the next government, leave the discussion table open 
	but do not hide their caution.   The 
	company confirms the path traced due to expensive energy, and the fact that 
	the Energy release does not meet the needs – comments Francesco Garau, 
	Filctem regional secretary. Instead, he confirms the study launched to 
	initiate a change in production towards the materials for the batteries of 
	the future.  As trade unions we reject 
	the blank Cig, strongly emphasizing the fact that the main problem to be 
	solved is that of the energy issue. November 23, 2021 - Glencore has announced it will place its zinc sulfide in Portovesme, Italy, on care and maintenance until the end of 2021 as it waits for a "meaningful change" in power market prices. The mining company said it decided to suspend operations at the Portovesme srl due to high power prices in Europe. It described Portovesme srl as being "highly dependent" on competitive and stable electricity prices. Additionally, it said operations less dependent on market prices, such as Waelz and SX, will continue to operate normally. "The decision will have an impact on approximately 400 direct employees and a range of associated contracting services," Glencore said. "Portovesme srl will continue to review this decision against the backdrop of the European energy market." According to Glencore, Portovesme srl is the only primary zinc and lead producer and has an annual capacity of 100,000 tonnes. June 5, 2009 - Glencore said it had placed its 80,000 tonnes per year (tpy) lead production line at Portovesme in Sardinia on temporary care and maintenance.  |
