SINGAPORE, June 11 (Reuters) - Global infrastructure

investors Actis and I Squared Capital are among companies

considering bids for Beijing Capital Group's wholly-owned

Singapore waste management company ECO, according to two sources

with direct knowledge of the matter.

Others interested companies include Singapore's Keppel, the

sources said, adding that the parties are working with financial

advisers to weigh making binding bids for ECO Special Waste

Management.

China's Beijing Capital had hired Citigroup ( C/PN ) last year

to sell the company in a deal that could fetch $300 million to

$400 million, Reuters reported in December.

Deadline for the bids are due as early as end of this month,

the sources said, adding that deliberations are still ongoing

with no final decisions made and the firms could decide against

pursuing a deal.

The sources declined to be named as the matter was private.

Actis, I Squared and Keppel declined to comment. ECO,

Beijing Capital did not immediately respond to Reuters' requests

for comment.

Beijing Capital bought the business from private equity firm

Navis Capital for S$246 million ($181.89 million) in 2015.

Investors' interest in Southeast Asia's waste management

sector has grown amid the region's rapid growth in population

and shift towards greener and cleaner energy and environment.

In 2022, a Keppel consortium bought a 80% stake in

Singaporean environmental services firm 800 Super Holdings for

S$304 million.

Beijing Capital operates in the wastewater treatment, water

construction, and real estate development businesses in China.

It also has businesses in financial services and culture and

sports sectors, its website shows.

ECO, founded in 1997, provides waste management services in

Singapore and is located in Tuas View Circuit with facilities

and a fleet of more than 40 waste collection vehicles, according

to its website.
