WITH TOBACCO The tobacco leaf has been associated with health hazards for humans, but a part of the plant deemed as waste—its stalk—may soon become the next construction material star.

TOBACCO stalks, by-products of tobacco processing and once considered waste, ready to be turned into termite-resistant additive for plywood adhesives.

neers on how to turn the waste into something useful. The stalks were by-products of tobacco processing and were already considered waste. Acda, Jimenez said, thought of using the stalks in making particle board. The particle board exhibited a resistance to termites after tobacco particles were mixed in its composition. In the tests conducted by Acda, particle boards with tobacco weren’t eaten by termites, which eventually died of hunger. “But the problem with that was we don’t have a particle board industry anymore. So when I applied for my PhD dissertation, [Acda] suggested that I use tobacco stalk as additives in the glue used in plywood,” Jimenez told the BusinessMirror in an interview.

F an apple a day keeps the doctor away, then a tobacco at bay sends the termites astray.

This is a simplistic explanation of what a Filipino engineer discovered about the potential of tobacco to be the next construction material star. Juanito P. Jimenez Jr. of the Department of Science and Technology Forest Products Research and Development Institute (DOSTFPRDI) studied the use of tobacco stalk particles as additive in glues used in plywood production. In his study, he found out that tobacco’s insect repellency and scavenger properties work well in plywood as they solve two of

its major problems: termites and formaldehyde emissions.

Termite repellency

JIMENEZ said tobacco’s property to repel termites—due to its nicotine content—has been known for decades already. But it was only through his adviser’s—Dr. Menandro N. Acda— work that the tobacco trait was put to real use. Jimenez recalled that National Tobacco Administration (NTA) brought tobacco stalks to DOSTFPRDI and sought help from engi-

PARTICLE board using ground tobacco stem as extender, filler, termiticide and scavenger.

Filler

JIMENEZ initially formulated a glue containing tobacco stalk particles or crushed tobacco stems that look like dust as a filler. He would cut up tobacco stems into chips, dry them, chip again, and then ground them into fine coffee-powder-like particles. The particles, which he calls dust, are then mixed with other components to create a glue treatment. To test if the treatment is effective against termites, he placed four panels with varying levels of tobacco-dust glue in a drum with a termite nest in the middle. “If given the choice, the termites would eat first the panels without treatment. After weeks the nest would lose activity and eventually die due to starvation,” he explained. “The other panels with tobacco glue were unscathed,” he added. Continued on A2

Economic twilight zone: Bonds that charge you for lending By David McHugh & Paul Wiseman | The Associated Press

RANKFURT, Germany—Imagine lending money to someone and having to pay for the privilege of doing so. Or being asked to invest and informed of how much money you’ll lose.

Sounds absurd, but increasingly that’s the global bond market these days. A rising share of government and corporate bonds are trading at negative interest yields—a financial twilight zone that took hold after the financial crisis and has accelerated on fear that a fragile global economy will

be further damaged by the US-China trade war. On Wednesday, for the first time ever, the German government sold 30-year bonds at a negative interest rate. The bonds pay no coupon interest at all. Yet bidders at the auction were willing to pay more than the face value they

would receive back when the bonds mature. The sale added to the mountain of negative-yielding bonds around the world that investors have gobbled up, suggesting that they expect global growth and inflation to remain subpar for years to come. After all, accepting a negative yield on a bond—agreeing, in effect, to lose money in exchange for parking money in a safe place— could reflect expectations that yields will sink even further into negative territory. "You’re essentially paying a warehouse fee by paying these negative rates," said Jim Bianco of Bianco Research in Chicago. Worldwide debt with negative rates has surged to $16.4 trillion

from $12.2 trillion in mid-July and $5.7 trillion in October, Bianco said. "Until a few months ago, negative-yielding debt was an interesting curiosity," he said. "In the last three months, it’s become a mainstay in the marketplace." The negative-yield phenomenon — 87 percent of it in Europe and Japan combined — is above all sign of pessimism about the future. "This is like a temperature gauge for the economy, and it says the economy is sick," said Sung Won Sohn, business economist at Loyola Marymount University in California.
