This lesson teaches you how to talk about composting and reducing waste in Mandarin Chinese. You will learn useful phrases for sorting garbage, explaining what can be composted, and encouraging roommates or family members to compost food scraps. The focus is on everyday conversation about waste, not general sustainability. You will practice key verbs such as 分类 (fēnlèi, to sort), 堆肥 (duīféi, to compost), and 减少 (jiǎnshǎo, to reduce), and you will see how to use 应该 (yīnggāi, should) to give suggestions. By the end, you should be able to hold a short conversation about what to do with kitchen waste and why composting matters.
By the end, you can…
- name common types of waste and say what can be composted in Mandarin.
- suggest composting and reducing waste using 应该 and related expressions.
- ask and answer simple questions about sorting trash and making compost.
Listen once. Try it slowly. Then say it without looking.

Make it make sense
Useful pattern
The pattern 应该 (yīnggāi) + verb is the most common way to say 'should' in Mandarin. It works for suggestions about waste: 我们应该分类垃圾。 (Wǒmen yīnggāi fēnlèi lājī. 'We should sort the trash.') To make it negative, use 不应该 (bù yīnggāi): 你不应该把电池扔进厨余桶。 (Nǐ bù yīnggāi bǎ diànchí rēng jìn chúyú tǒng. 'You shouldn't throw batteries into the kitchen waste bin.') You can also soften a suggestion with 可以 (kěyǐ, can/may): 我们可以用果皮做堆肥。 (Wǒmen kěyǐ yòng guǒpí zuò duīféi. 'We can use fruit peels to make compost.')
When to use it
Use 应该 when you are giving a recommendation or stating what is proper, especially with roommates, family, or colleagues. It is direct but not rude. For a gentler tone, add 我觉得 (wǒ juéde, I think): 我觉得我们应该少用塑料袋。 (Wǒ juéde wǒmen yīnggāi shǎo yòng sùliàodài. 'I think we should use fewer plastic bags.') If you are asking for agreement, use 吧 (ba): 我们把厨余垃圾堆肥吧。 (Wǒmen bǎ chúyú lājī duīféi ba. 'Let's compost the kitchen waste.') Avoid using 应该 with a harsh tone; in Chinese, politeness often comes from context and softeners rather than from changing the verb form.
Listen to each line, then take one part and reply out loud.
我们家每天有很多厨余垃圾，应该怎么处理？
Our family has a lot of kitchen waste every day. How should we deal with it?Wǒmen jiā měitiān yǒu hěnduō chúyú lājī, yīnggāi zěnme chǔlǐ?我们可以把果皮和菜叶用来堆肥。
We can use fruit peels and vegetable leaves to make compost.Wǒmen kěyǐ bǎ guǒpí hé càiyè yònglái duīféi.那塑料和剩饭呢？
What about plastic and leftover food?Nà sùliào hé shèngfàn ne?塑料要另外扔，剩饭也可以堆肥，但是要先分开。
Plastic should be thrown away separately. Leftover food can also be composted, but you need to separate it first.Sùliào yào lìngwài rēng, shèngfàn yě kěyǐ duīféi, dànshì yào xiān fēnkāi.A little context goes a long way
In many Chinese cities, household waste sorting is required by local regulations, and bins are often labeled 厨余垃圾 (kitchen waste), 可回收物 (recyclables), 有害垃圾 (hazardous waste), and 其他垃圾 (other waste). The exact rules and labels vary by city, so it is useful to ask a neighbor or check your community notice. Composting at home is less common in dense urban housing, but small balcony compost bins are increasingly available. When talking about waste, a practical tone is usually more welcome than a moralizing one.
One thing to watch for
Using 堆肥 as a general verb for 'to reduce waste', as in 我们应该堆肥垃圾来减少浪费。
Try this instead: 堆肥 specifically means 'to compost', not 'to reduce'. For reducing waste, use 减少垃圾 (jiǎnshǎo lājī) or 减少浪费 (jiǎnshǎo làngfèi). Say 我们应该减少垃圾，把厨余用来堆肥。 (Wǒmen yīnggāi jiǎnshǎo lājī, bǎ chúyú yònglái duīféi. 'We should reduce waste and use kitchen scraps for compost.')
Your turn
Try answering out loud before checking a possible answer.
1How would you suggest to a roommate that you should compost fruit peels?
Show a sample answer
我们应该把果皮用来堆肥。
This uses 应该 to make a suggestion and 把 to mark the object. You could also say 我们可以把果皮堆肥。 with 可以 for a softer tone.
2What is the difference between 厨余垃圾 and 其他垃圾?
Show a sample answer
厨余垃圾 is kitchen waste, such as food scraps and peels; 其他垃圾 is other waste, such as used tissues and dirty packaging.
The distinction matters for sorting. Exact bin categories can vary by city, so local labels may differ slightly.
3Translate: 'Plastic should be thrown away separately.'
Show a sample answer
塑料要分开扔。
要 (yào) here means 'should' or 'need to'. You could also say 塑料应该另外扔。 with 应该, which is also correct.
Use 应该 to suggest composting and 把 to say what you compost; keep waste categories clear, and check your local rules because they vary by city.
