ROME, May 25 (Reuters) - Italian businessman Manlio Cerroni thinks a monument would be a fitting recognition of his services to Rome. Instead, the 86-year-old, who spent 60 years building a global empire and a personal fortune on trash, is facing trial on a string of charges.

Italian prosecutors say Cerroni - "Il Supremo" to his aides - oversaw a web of companies and individuals colluding to defend his monopoly over trash disposal in and around the Italian capital, including his Malagrotta landfill, Europe's largest, which closed last year after European Union authorities ruled it unfit to treat waste.

Cerroni's lawyer, Giorgio Martellino, says his client denies all charges, which also include fraud and improper waste treatment, but declined to be interviewed.

Several local politicians from the Lazio region, of which Rome is the capital, are also due to stand trial for collusion.

Cerroni was earlier this year put under preventive detention at home, but has since been released on bail, on condition he doesn't set foot in Rome, his lawyer said.

While being questioned, he told prosecutors: "You should build me a monument for everything I've done for this city," according to a judicial source familiar with the questioning.

The European Commission takes a dim view of Italy's waste industry. It estimates that trash is treated and disposed of unlawfully in 100 of Italy's 250 official waste-management sites. Italian police estimate there are also 1,000 illegal sites.

In and around the city of Naples, for example, the Camorra organised crime group has since the 1990s taken over lucrative waste-management contracts, dumping trash from all over the country and other parts of Europe in unauthorised fields or landfills, according to testimony and documents from various legal cases. Industrial waste has often been illegally stored or burned, releasing toxins that have contaminated much of the area.

Last month, an Italian police officer who had spent many years in and around the so-called Land of the Fires - a vast area south of Naples where toxic trash has long been dumped and burned - died of a tumour that the Italian state officially recognised was related to his work there.

Rome, Italy's biggest city, also has its trash problems.
