So if no word "rechargeable" on Duracell battery, then it is not rechargeable, correct?
I used to buy Duracell battery in Costco, not expensive at all. It does not indicate "rechargeable" anywhere on the battery, then I guess it is not chargeable, just threw them away when battery runs out.
But I am thinking about buying some rechargeable battery and a charger, so that I can produce less harmful materials into the environment.
You can also look at the chemicals that make up the battery. Alkaline batteries are not rechargable.
Rechargable batteries are usually NiCD, NiMH, or Li-ion.
And of course, they are relatively more expensive to their non-rechargable counterparts.

Errrr... not really. The reactions involved are two way. You CAN put charge back into alkaline batteries, but it isn't commonly done for a few reasons: You can't get them charged back to near what the initial stored energy was, the results of a recharge are inconsistent, each recharge is a case of diminishing returns, there is enough waste heat in the process that it can cause damage, the possibility of leakage is increased, and the chances of the powered device crapping out at an unexpected time are greatly increased.
Where recharging an alkaline might make sense is where the recharged battery will be unconnected to a circuit until use, and then has to release a fairly short burst of energy (three or four minutes or less) and can die without damaging anything.
If you buy some rechargeable batteries, look closely at the voltage. They will generally be less voltage than a comparable non rechargeable battery. A rechargeable AA battery runs 1.2V while your non rechargeable battery runs 1.5V. Whether or not this causes a problem w/ what you're putting them in just depends. I know that w/ my aux bike H-lamp which takes 1.5V AA batteries, the non rechargeable ones gave a noticeably dimmer light. I don't like to use the rechargeable ones in my film cameras either because the difference between 1.2V and 1.5V will throw off my light meter, as it really needs 1.5V to be accurate.
I'm not big on damaging the earth either, but switching to rechargeable batteries would not make a significant difference, it's like one drop in an ocean. Something like driving a gas burning car, from the making and maintenance of, is a totally toxic endeavor. Ditching that for a an EV car, or ditching the car entirely and riding an eBike and using public transit along w/ UBER or renting a vehicle if it's occasionally necessary, now that does make a significant difference in the pollution of the planet.
There are a lot of other ways to make a difference too: keeping your electronic devices as long as they work well and not constantly ditching them for those that are simply more shiny, buying clothes and other items from thrift stores, buying or making things like shelves, furniture, tables etc from recycled items and materials from Habitat for Humanity, buying used appliances instead of the new ones......

The simplest and safest way: if you want a rechargeable battery, buy a rechargeable battery. I have no idea why the OP has to worry about the "environment" relating to a rechargeable battery versus a non-rechargeable one. Both are recyclable, and at one point or another both left environmental damage during their ingredient gathering and construction processes.
Just be aware of the following warning that's usually posted on the battery's label: make sure that you charge the battery as instructed by the battery manufacturer. For example, I have several battery-operated power tools, and different chargers. Most of the batteries are Lithium, but not all are. I still can recharge all non-lithium or lithium Dewalt batteries with the charger designed for lithium batteries, but if I use the chargers that aren't designed to charge lithium batteries the lithium battery can get very hot and even explode.

This.
Key thing to using rechargeable batteries is using a proper charger. If one didn't come with the batteries, make sure the one you buy was actually designed for the type of rechargeable batteries you have.
Also, do NOT do this:
