Isiaho, a consultant on labour issues, said the collapsed industries cut across and the factors that led to the collapse need to be addressed.
He said Kabazi Canners, which provided a market for tomato and peas farmers from the Kabazi and Subukia, had closed down, while Njoro Canners had scaled down production.
"The government needs to provide a tangible solution and road map for the revitalisation of the industrial sector. You cannot establish an industrial park or an agro-processing park when already existing firms are collapsing," Isiaho added.
"We also have other textile firms as Robins, Lamson and Nakuru Fibres, which have closed down. How does the government commit to reviving cotton growing while textile firms have closed down? What incentives is the government offering those intending to set up factories in the newly created industrial hubs?" Isiaho posed.
Most of the giant firms stood tall in their heyday, with imposing buildings to boot.
Today, a walk to Industrial Area reveals a desolate place with most buildings, previously operating as factories and warehouses, empty.
This is the sorry state of affairs in Nakuru, where many industries have shut down over the past three decades.
A human capital and business consultant, Dr Stanley Karanja, said the government needs to have a well-developed and thought-out plan to address the critical issues that have negatively impacted on business and industrial enterprises in Kenya before rushing to set aside land for industrial hubs.
"We are in a worrying situation. The Kenya Industrial Estate in Nakuru town is in a pathetic situation as the sheds, which were previously meant for light processing industries have been turned into motor vehicle garages, and yards for the sale of second-hand motor spares, or outlets for the sale of animal feeds," Dr Karanja said.
The consultant, who previously worked as a marketing manager with Coca-Cola Company and contested for governor in the county, said it would be impossible to attract major investments in the newly created industrial parks when factors that led to the collapse of previous industries remain unaddressed.
"It is simple logic, businesses and industries cannot be collapsing, and then you think of establishing new ventures before first addressing the factors that led the initial businesses, some of which were established 100 years ago, to fail," Dr Karanja said.
He said the collapse of industries had led to massive unemployment in Nakuru town.
"Hundreds of university and college graduates who are well trained in finance, human resource management, electrical and electronics engineering, food production, chemical engineering, and dairy production, among other fields, are now hawkers while others operate boda boda or matatus or do menial jobs," Karanja said.
Karanja added that the collapse of industries had denied workers quality jobs and the opportunity to earn good and regular incomes.
"If a proper study is conducted, it will reveal that the life span of these graduates doing menial jobs has reduced," Karanja said.

A former chief for the Lanet location, Stephen Lelei, said the collapse of industries had led to unemployment and affected family stability.
Mr Lelei worked with Nakuru Blankets, which has scaled down its workforce from 3,000 to 300.
The former administrator said he was employed at Nakuru Blankets in 1982 as a general worker before rising through the ranks to a weaver, production clerk, wages officer, to factory welfare officer.
He recalled that at the peak of production in the late 1980s, the textile production firm had 3,000 workers whom he was supervising and operated three shifts a day.
Lelei said the textile firm led to the growth of the neighbouring Free Area trading centre and Kiratina estate.
He said the liberation of the economy in mid-1992 impacted negatively on the operations of most industrial firms due to the influx of cheap textile products.
Lelei later resigned from the textile firm in 1993 when he was appointed chief, a position he held until his retirement in 2017.
Community leader Eliasif Magoma, former employee of Eveready East Africa, said the firm had 1,200 employees until the mid-1990s when it started experiencing problems due to changes in technology.
"The influx of cheap dry batteries from China and other Asian countries affected the production of Eveready Limited while the demand for dry batteries also significantly reduced as the government intensified rural electrification programmes and other Kenyans installed solar panels," he said.
Magoma said several other industrial establishments, such as Nakuru Oil Mills, which was manufacturing edible oil from sunflower and popcorn had to cease operation following the influx into the market of cheap cooking oil. "The liberalisation of the economy was done haphazardly as the government failed to take some safety measures to safeguard our industries," Magoma added.
He said Industrial Area was in the 1980s and mid-1990s a hive of activity as most industries operated 24 hours.
"The youth are now venturing into informal sectors where incomes are low. This has led to the growth of slums as people cannot afford decent houses," Magoma said.
The civil rights activist further said that many houses in Kaptembwo and London, which neighbour Industrial Area were vacant as people had relocated to rural areas.
A former employee of the Ministry of Public Workers, Richard Masika, said he was well conversant with Industrial Area as he used to inspect construction work in the area.
Masika, now a Kanu official said: "Industrial Area is a ghost place, previously the area was teeming with workers at any given time as industries operated 24 hours."
He said the economy of Nakuru City had declined.
"Previously, Nakuru had many entertainment joints that operated throughout the night, but nowadays the town is dead asleep by 9pm. We have few bars and restaurants operating throughout the night. This has also impacted negatively on taxi business and petrol stations, among other businesses," Masika recalled.
The Kanu official said over the past few years, only Simba Cement and Royal Tanks have set up major industrial operations in the region.
He said several small firms making roofing materials had set up their operations on the outskirts of the town.
A former worker in the sisal industry, Joel Nyandieka, said the collapse of sisal farming in Mogotio had also led to the collapse of industries involved with weaving and spinning.
Nyandieka served as a shop steward for the Kenya Agricultural and Plantation Workers Union (KAPWU). He worked with Majani Mingi Group of Companies.
Majani Mingi Group owned several sisal firms, which included Athinai, Majani Mingi, Lomolo, and Mogotio sisal farms that employed over 10,000 workers by the mid-1990s. The sisal firms closed shop.
