The scheme began its downturn in 2002 when the PBK started experiencing financial challenges linked to mismanagement, corruption and theft of its resources.
The pensioners obtained a court order allowing them to wind up the scheme in December 2016, and it was put under receivership in May 2017.
To pay off their claims, the pensioners proposed that the government inject more money into the company or have its non-core assets spread in different counties sold.
"PPCK wrote to the National Treasury seeking permission to sell some of its houses and land to clear our dues. The matter has been pending before the Cabinet for too long now," said Tinga.
He pointed out that they were in doubt with the valuation done on some of the assets they had proposed to be sold, saying that they had been grossly undervalued.
"We want a proper valuation of the assets which were undervalued by government valuers. Some houses within Nakuru City are worth up to Sh800 million but the valuers had set their value at Sh300 million," said Tinga.
According to them, undervaluation of the assets would not only lead to loss of revenue by the government but also impede their payment process as more assets would have to be sold.
The Pyrethrum Board of Kenya Staff Superannuation Scheme was established in 1991.
Each member was contributing five per cent of his or her salary towards the scheme while PBK was matching the contribution.
The government is in the process of reviving the pyrethrum sector, which was once the country's highest foreign exchange earner through exports.
