Plastic straws take a long time to break down naturally, so replacing them with environmentally friendly, reusable alternatives can help keep hazardous pollutants out of the environment. Although you can always buy bamboo straws online or from good stores in the home, you can also try making your own from all healthy bamboo shoots. Bamboo straws are still broken over time, but as long as you handle them properly you can use them for up to a year before putting them in a recycling or compost bin.
[ Edit ] Step
[ Edit ] Cutting the Bamboo
- Choose healthy bamboo stalks that are as thin as a pen. Look for shots that are just as thin or thinner than a pen so you can comfortably drink through them. Choose bamboo stems that have at least between nodes, which are the horizontal bands on the stems. 
- Avoid using stalks that are thicker than because you may have difficulty using the straw.  Watch out for spotted or rotten bamboo as it can weaken your straw or have harmful bacteria.
- It's okay if the bamboo stalks have small bends or angles as long as they're mostly straight.
 Pinch the bamboo stems with pruners at a 45 degree angle. Place your cut just above one of the bamboo nodes so that it can easily grow again after you cut it. Position the pruners so that the leaves make a 45-degree angle to the stem and squeeze the handles together firmly. Leave at least 1-2 nodes on bamboo so they can continue to grow. 
- Avoid making straight cuts as it can catch water and cause bamboo to develop.
- You can also saw the bamboo logs at a 45-degree angle with an arc saw if you do not have cutters available.
- Leave the bamboo vertically in a dry area until it turns brown. Place the lower end of an ash block or brick so that it is off the ground to avoid water damage. Tilt bamboo vertically against a wall or rack to help guide fluid inside and out of the stem. Allow the bamboo to dry completely until it has a tan color, which usually takes about 2-3 weeks. 
- Avoid placing bamboo horizontally as it may not flow properly and may develop rat.
- If you are planning to dry bamboo outside, try using a south facing wall to make sure it gets sunlight throughout the day.
- Saw bamboo in segments between the nodes. Place the bamboo stalk on the work surface so that it overhangs the edge. Hold the stalk firmly against your work surface with your non-dominant hand and make a straight cut across the node with an arc saw. Then remove the node on the other side of the straw and leave a gap. Continue cutting straw from the stalk length. 
- Usually, some of the bamboo will make between 4-16 straws depending on their lengths.
- Avoid making straws shorter than they may not be high enough for most cups.
- Do not use pruners to cut dry bamboo because you can make the stems crack or cut easier.
[ Edit ] Grinding and cleaning the straws
- Grinding the ends of the straw with sandpaper to remove sharp edges. Place a piece of fine-grained sandpaper, such as 180- or 220-grain, over one of the straw's cut ends. Apply hard pressure and swirl the sandpaper around the straw to taper the end. If you still have trouble smoothing the edge, hold the sandpaper face up to the work surface and rub the end of the straw until it feels even. Repeat the process at the other end of the straw. 
- Avoid using the straw without grinding it first because you could easily cut your mouth or get splinters.
- Blow saws off of straw sometimes so you can see what you are working on.
- Smooth the outside of the straw with sandpaper or a bellow grinder. Wrap a piece of 180-grain sandpaper around the outside of the straw and rub it up and down the length of the bamboo. Turn the straw as you work to smooth it evenly. If you use a bellows grinder, use safety goggles to protect yourself from kickback. Hold the ends of the straw and lightly push the side of the straw against the moving belt on the grinder. Move the straw back and forth so that you sand the outside evenly and rotate the straw as you work around the bamboo. 
- It's okay to leave bumps or angled parts on the length of the straw if you want.
- Don't use too much pressure when grinding, otherwise you can crack bamboo.
- Run sandpaper through the center of the straw. Cut a strip of 180- or 220-grain sandpaper that is about wide and long. Roll the piece of sandpaper longitudinally to form a long spiral. Insert the end of the bobbin into the center of the straw and push it through the length of the straw. Pull out the sandpaper from the other side. Repeat the process 3-4 times to smooth the inner edges. 
- If you have trouble pulling it through bamboo, press the sandpaper with a thin stick or thread.
- Clean the inside of the suction pipe with a pipe cleaning brush. Press the thin end of the pipe cleaning brush into the center of the straw. Turn the brush clockwise 1–2 before pulling out the brush. Continue vacuuming the suction pipe from both sides 5-6 times, or until you see no visible dust when removing the brush. 
- Cleaning brushes usually have rigid brushes in a cylindrical or tapered shape that help to clean the sides of the pipes, and you can buy them from your local hardware store.
- You can also try to direct compressed air inside the suction pipe and blow out the dust for 1 to 2 second bursts on each side until you see no more coming out.
[ Edit ] Process and use the straw
- Boil the straw in salt water for 10 minutes before using it. Bring water mixed with 2 teaspoons (12 g) of table salt to a boil on your stove before setting the straw. Put the lid on the pot and let the straws boil for 10 minutes to kill any bacteria. Remove the straws from the water with a pair of pliers and place them on a towel in a well-ventilated area to cool and dry, which will take about 30 minutes. 
- Make sure you use a pot large enough to completely submerge the straws, otherwise they will not be disinfected properly.
- You can use the straw as soon as it cools.
- Wash and dry the straw by hand immediately after you are done using it. Use the straw that you usually make with all types of drinks. When finished with the drink, give the straw a quick rinse with clean water. When you have time for a more thorough cleaning, rinse the straw with soapy water. Place the straw in a well-ventilated area so that it can dry. 
- Avoid leaving any sticky or sugary drinks dry inside the straw as they can weaken the wood or cause build-up inside.
- If you have build up inside the straw, try scraping it out with a pipe cleaning brush.
- Store the straws in a dry place that is room temperature, such as a cabinet.
 Recycle or compost straw if the ends start to split. Check the ends of the straw when using it to make sure the ends do not crack. If you notice that the straw is broken, put it in your recycling bin or compost bin instead of your usual junk. Usually, your bamboo straw will last about a year as long as you take good care of it. 
- Make several straws at a time so that you have one replacement ready when you are done with another.
[ Edit ] Tips
- Make several straws at a time so you can take one with you when you travel and leave one at home. That way you always have a simple replacement too.
[ Edit ] Warnings
- Always check the ends of the straw before using them to avoid damaging yourself because they could split or splinter.
- Wear safety goggles when using a belt grinder if bamboo breaks while you work.
- Never touch a moving grinding machine as you can seriously injure yourself.
