Purify the Air with a Single Straw: How Grass Straws Make Carbon Emissions Disappear?

Hi, we are Wonder Greener. Today, we want to share some good news that we've been keeping close to our hearts for a long time. This time, our pride comes from more than just a single straw! We can finally share the real data with everyone. Remember how we initially told everyone how eco-friendly Grass strawis? We said it was natural, naturally degradable, and better than plastic straws. But honestly, because the world of eco-friendliness is too complex—too many traps of "Fake sustainability" that we were afraid of being misunderstood, afraid of being questioned. We knew that simply saying “very eco-friendly” wasn’t enough.

So, we decided to dig deep into the true story behind grass straws. From cultivation to natural decomposition, every step was mapped and scrutinized. Over these days, we’ve followed third-party verification body, we reviewed every carbon and biodiversity report. The journey was tougher than we imagined, and at times we wondered if it was worth it.
Yet when the data finally arrived, it made everything worthwhile.

Our grass straws are truly "carbon negative"!

Remember we said that grass absorbs CO₂ as it grows—and now we can measure it. From nature to your hands, every step of this carbon-negative journey is accounted for.

Station 1: Grass Fields at Work — Capturing Carbon Naturally

Our journey starts in a vibrant grass meadow. Since grass can be harvested without plowing, our farms do more than produce, they act as nature’s carbon-capturing wizards. According to Gold Standard method (Under verification), A single hectare of grass can capture as much as 400 tons of CO₂. You might not have a sense of this number, in other words, each grass straw can capture an estimated 20g of CO₂ as it grows! This means our sustainable straws start contributing to the planet from the moment they’re planted — not just reducing emissions, but actively sequestering carbon.

From farm to your hands: a carbon-negative journey

Curious how a grass straw travels from the field to your hands? Our Production process is simpler than you might think— no complex chemistry or energy-intensive processes— just a simple transformation of nature’s gift into an eco-friendly product.

This process, total carbon emissions only 4.412g, every step stands up to scrutiny:

1. Materials and process (2.3263g) : Once harvested, our grass is carefully washing, trimming, hollowing, drying, and sterilization. Emissions mainly come from equipment and power, but energy use is still far lower than traditional plastic straws.
2. Packaging and delivery (1.9723g) : From packaging to delivery, we work to minimize our carbon footprint at every step.
3. Sales and disposal (0.1135g) : This stage covers carbon emissions from sales to consumer use, including the final disposal of packaging.

A simple calculation reveals the amazing value of grass straws:
4.412g (Production carbon emissions) – 20g (Plant carbon sequestration) = -15.588g.

This means that even including emissions from production, the straw’s life-cycle carbon footprint remains negative. It not only offsets its own emissions but also returns 15.6g of carbon credits to the planet. That’s why we proudly call it a fully guilt-free, disposable straw from start to finish.

Beyond carbon, we’ve achieved even more

But that’s not what makes us proud—our journey goes beyond the numbers.

Promise 1: From leaf to soil, free of microplastics

Where does your eco-friendly straw go after use? Our grass straws can be fully biodegradable in natural environments. Unlike bioplastics that require industrial composting and may still turn into microplastics, this straw can be thrown into your food waste bin or buried in a plant pot. It naturally decomposes, returning to the earth — because it is a plant. That’s true zero waste.

Promise 2: Reviving nature, boosting biodiversity

Our grass farms aren’t just for cutting carbon. They’re thriving, living ecosystems.
You may not know, but our biodiversity report commissioned from National Sun Yat-sen University shows that Aquatic insects in our grass fields are far more than in conventional rice fields! This means our cultivation not only avoids harming the environment but also creates a better habitat for small creatures.

Promise 3: Backing local farmers, boosting rural regeneration

We’ve also achieved social well-being. By growing grass, our farmers enjoy extra income, and our partnerships provide more than employment — they offer a path to revitalizing rural economies. From carbon to biodiversity, and from carbon reduction to social well-being isn’t for us to claim — it’s clearly documented in our reports.

Sincere words from Wonder Greener

Today, we can finally say with confidence: Every bit of your support is part of a genuine sustainability effort.

We know that the market is full of eco-friendly utensils, and it can feel exhausting.
Grass straws are different. They’re not just a straw — they embody a choice that considers convenience, the planet, and society. Thank you for believing in us.
Our grass straw is truly a guilt-free, disposable straw from beginning to end.
