From compost heap to worm tray: that's how you compost

© Offered by

A huge compost heap or a small composting bucket? You can process your organic waste in various ways. There are many nutrients in compost and it makes the flowers in the garden more beautiful. How do you compost properly?

"Compost is good for the garden and plants, because it is a beautiful, natural fertilizer," says Emiel Elferink, lecturer in Sustainable Soil Management at Van Hall Larenstein University of Applied Sciences. "There are many nutrients in it. If the soil in your garden is not crumbly and not black, it could use some compost."

Peat, potting soil and peat soil are also good natural fertilizers for your garden, says Elferink. "The advantage of compost is that it makes the soil and plants more resilient to wet and dry periods. The soil is also charged by the release of more iron, aluminum and magnesium. This makes flowers and plants grow better and makes them more beautiful." / p>

'Composting saves energy'

In addition to composting being good for your garden and plants, it is also possible to opt for environmental reasons. Approximately 5 percent of the collected organic waste is rejected and incinerated, for example because it contains scraps of paper and plastic, according to information gathered by the MilieuCentraal information organization. Organic waste that is not separated and disposed of with residual waste is also incinerated.

Two-thirds of well-collected organic waste is processed into compost. This compost is used by horticulturists and municipalities to improve the soil. One third of the organic waste is fermented and, in addition to compost, also produces biogas that can be used as a green gas and electricity source.

"The advantage of self-composting for the environment is that less waste is transported and processed needs to be ", says Linda Nijenhuis of MilieuCentraal. "That saves energy, because you keep the cycle small. And it provides you with a free soil improver."

Which form of composting do you choose?

There are a few different ways you can compost. "Which one you choose mainly depends on the size of your garden and the amount of waste," says Nijenhuis. "If you have no garden waste, a closed system, such as a compost bin, is the most suitable. If there is enough space, you can make a compost pile in your garden"

A compost bin or composting drum is useful for those who tight lives. You can also make or buy a so-called worm tray. "Worms crush the organic waste," says Elferink. "And we are talking about red worms or tiger worms, not earthworms. They come naturally in a compost heap. For example, if you want to use them in a worm bin, you can go to a forest and look for them there."

Why compost if you don't have a garden? "You can also use compost in your planter, mini garden or when growing herb plants," says Elferink. "You can mix the compost well with some potting soil. You can also make compost tea and use it as a nutrient for plants. The beneficial bacteria and fungi keep plant diseases out."

How do you compost in the right way?

Just throwing everything together and leaving it somewhere is not the best idea. "If you don't bring enough oxygen into your compost, harmful greenhouses can arise, such as methane and laughing gas," says Nijenhuis. "That is why you have to re-scoop the compost well. That also helps to prevent odors and to make composting faster. In addition, it is good to keep your compost moist. But also not too wet. Therefore, provide some protection against the sun and rain. "

Different waste ensures good compost, says Nijenhuis. But not everything that is allowed in the GFT container is also suitable for your own compost. "For example, cooked leftovers are often too salty and too fat and therefore difficult to compost. They can also attract mice and rats."
