Is MAGIC WM-218 really environmentally friendly?

In today's world where sustainability and environmental protection are becoming more and more important, many people are looking for environmentally friendly alternatives to conventional products. An interesting question is whether the ESENG MAGIC WM-218 Whiteboard Markers are really environmentally friendly. Let's look at the data on plastic use to answer this question.

Plastic consumption in comparison

Disposable whiteboard markers

A conventional disposable whiteboard marker weighs about 13-15 grams per pen. For our calculations, we assume an average of 14 grams per pen.

ESENG MAGIC WM-218 whiteboard marker

An ESENG whiteboard marker weighs 17.5 grams per pen. There is an additional weight of 2.5 grams per replacement ink cartridge.

Example calculation for 6 ink cartridge replacements

If each ESENG whiteboard marker is refilled a total of 6 times, this corresponds to the use of 7 disposable whiteboard markers. The calculation then looks like this:

• Disposable whiteboard markers : 14 grams/pen * 7 pens = 98 grams
• ESENG Whiteboard Marker : 17.5 grams (pen) + 2.5 grams * 6 (ink cartridges) = 32.5 grams

This results in a plastic saving of:$\frac{<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">(</span></span>\mathrm{<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">98</span></span>}<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">-</span></span>\mathrm{<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">32</span></span>}<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">,</span></span>\mathrm{<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">5</span></span>}<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">)</span></span>}{\mathrm{<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">98</span></span>}}<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">\times </span></span>\mathrm{<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">100</span></span>}<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">=</span></span>\mathrm{<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">66</span></span>}<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">,</span></span>\mathrm{<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">8th</span></span>}\mathrm{<span\; class="katex"\; data-mce-fragment="1"><span\; class="katex-mathml"\; data-mce-fragment="1">\%</span></span>}$\frac{(98 - 32.5)}{98} \times 100 = 66.8\% 98 ( 98 − 32 , 5 ) × 100 = 66 , 8th%

Example calculation for 12 ink cartridge replacements

If each ESENG whiteboard marker is refilled a total of 12 times, this corresponds to the use of 13 disposable whiteboard markers. The calculation then looks like this:

• Disposable whiteboard markers : 14 grams/pen * 13 pens = 182 grams
• ESENG Whiteboard Marker : 17.5 grams (pen) + 2.5 grams * 12 (ink cartridges) = 47.5 grams

Conclusion

Using the ESENG MAGIC WM-218 whiteboard marker can reduce plastic consumption by over 65%. This calculation is based on each ESENG whiteboard marker being refilled several times. The more often you replace the ink cartridge, the greater the plastic savings.

Annotation:

All weights mentioned refer to the pens without ink. The ESENG MAGIC WM-218 whiteboard marker comes with an ink cartridge, so replacing the ink cartridge 6 times corresponds to a total of 7 uses.

By choosing refillable whiteboard markers like the ESENG MAGIC WM-218, we can make a significant contribution to reducing plastic waste while using a more environmentally friendly alternative.
