一，塑料垃圾桶按照用途可以分为家用，医用，商用，但塑料垃圾桶家用和医用的使用比例更高，在小区及公园塑料垃圾桶使用率比较低，究其原因，无非是家用和医用对于防水性能有要求，塑料垃圾桶的防水性和密封性都比较好，特别是医用，必须要防水性能好的，避免垃圾扩散，而小区和公园对于垃圾桶的耐用性要求高，由于都是普通生活垃圾，对于防水性要求要低于家用及医用，所以小区和公园常常采用钢木垃圾桶或是不锈钢垃圾桶甚至是大铁桶。   二，塑料垃圾桶的造型分为圆桶，方桶和异形桶，方型垃圾桶的造型比较强硬，圆形垃圾桶造型比较圆润，适合于和景观人融合，而异形桶较少，异形桶往往是作为景观的一部分或是广告之用。在颜色上塑料垃圾桶以蓝色和黄色居多，当然很多地方由于垃圾分类的需要又增加了绿色和黑色，用以分出不同的垃圾种类。
