By ZHAO RUIXUE | China Daily | Updated:2017-08-31 09:02For many people, cockroaches are despised pests that trigger feelings of disgust-but for Li Yanrong, the insects are a source of income.
On a 1,800-square-meter plot 2 kilometers from Shawan village in Jinan, Shandong province, the 50-year-old businessman has built a facility to research ways of harnessing cockroaches.
“We spent six years doing research into using cockroaches after finding that they can feed on kitchen waste and create no pollutants,” said Li, general manager of Qiaobin Agricultural Technology. Cockroaches are not just pests, but can be beneficial to society, Li added.
At a workshop in the plant, where simple equipment is used to process kitchen waste, the air smells foul. Every day, kitchen waste, which comes from the environmental sanitation agency, is broken down and piped into a concrete building filled with millions of cockroaches.
Li has 300 metric tons of American cockroaches that can eat 15 tons of kitchen waste a day, about 25 percent of the amount produced in the citys Zhangqiu district.
And he is planning to expand. He has signed a contract with a Beijing company that will invest in a new plant. “We will equip the new facility with high-quality equipment to ensure no odor is discharged,” Li said.
When the new facility is completed this year, the company will be able to process 60 tons of kitchen waste a day.
If the company can handle 100 tons a day, it will earn 7.59 million yuan ($1.14 million) a year, Li said. In addition, the company can earn 36.5 million yuan a year from selling protein feed produced from the eggs of cockroaches.
“A cockroach begins laying eggs when it is 4 months old. It lays one egg each week, and can lay eggs for eight months,” Li said.
“Using insects to solve big problems is being done around the world. The most successful case is Australias use of dung beetles to deal with cow dung, which prompted us to think of using cockroaches to deal with kitchen waste,” he added.
“We are the first in the world to do so and we have applied for patents for the project.”
Lis research team consists of five people all with masters degrees. Before their work with cockroaches, they focused on developing medical equipment.
“Using cockroaches to deal with kitchen waste is good for our country and for business,” Li said. “Social problems created by kitchen waste will be eradicated.”PhotoCeramic painted cultural relics on display in XianAmerican in Beijing lives his Chinese dreamHistoric temple all set for its 30-meter moveAerial view of Shanghai-Nantong Yangtze River Bridge under constructionXis Moments in TianjinFarmer makes a fortune by broadcasting village lifeXi pushes sports developmentHighlights from Xis speech at a workshopLatestAfghan children to get free treatmentTrademark: Court rules in favor of QualcommCeramic painted cultural relics on display in XianTravel getting easier-just ask the robotsAmerican in Beijing lives his Chinese dreamState Council NewsPremier’s question hits the ‘pain point’ of manufacturing industryState Council stresses sense of benefit for sci-tech researchersExclusiveHighlights from Xis speech at a high-level workshopDisability Prevention DayBuilding greener, cleaner ChinaEditors picksTravel getting easier-just ask the robotsChinese company plans hyperloop traveling at 1,000 km/hTen photos you dont wanna missTen photos from across China: Aug 18-24SpecialCelebrating 90th anniversary of PLAs establishmentAchievements made under Xis leadershipBACK TO THE TOPHOMECHINAWORLDBUSINESSLIFESTYLECULTURETRAVELWATCHTHISSPORTSOPINIONREGIONALFORUMNEWSPAPERChina Daily PDFChina Daily E-paperMOBILECopyright 1995 -var oTime = new Date();
