USING RECYCLED PLASTIC CONTAINERS
Its a common perception that all plastics are harmful to grow food in and should be avoided completely. Some people saying that using plastics to grow vegetables and fruits defeats the very idea of growing naturally or organically. Though it is true that plastic products are not natural, what will landless people use to grow their own food? They can opt to buy inexpensive plastic pots sure, but that would be spending more money, and most people grow their own food to save money. Re-using plastic containers is cheaper and it gives the object one more use before being recycled.
There are other materials that can be used of course, like wooden pallets but sometimes supplies are not always available and they don’t last very long. Using plastic containers to grow food is fine – provided you know which plastics to use. Some plastics are harmful and leach toxins to the soil especially when they are heated or exposed to sunlight or prolonged periods of time. Make sure to discard scratched or worn down plastic containers to avoid leaching of chemicals.
Common plastic containers used for growing:
- Food-grade 15-30 Litre buckets
- Plastic bins (totes)
- Yogurt and deli containers
