Compost can play an important role in gardens, but requires both space and time. Many people who live in apartments and do not have access to gardens have therefore turned to a new trend - the so-called bookashim method.

"The best thing about this method is that it can be done anywhere, it does not smell and is environmentally friendly," says Malin Sairio, who is a biologist and marketing manager for a site that sells products on the same theme.

Composting indoors

The method is suitable for anyone who likes to grow, but is especially suitable for those who live in urban environments and have difficulty composting outdoors.

- All you need is a bucket with taps and a special litter (bokashi litter) with microorganisms. The litter made from lactic acid and photosynthetic bacteria helps in the process and fermentes the food residues. In the bucket, food debris and litter are interspersed and when, after a few weeks, the contents of the soil are buried, the rapid conversion to nutritious soil can occur, says Malin.

Environmentally friendly method

In addition to the method being faster than regular composting, it is also more environmentally friendly, says Malin.

- Normal composting needs oxygen to work. When food waste gets oxygen, it becomes a hot process that burns a lot of nutrition and energy that disappears into the air like greenhouse gases, and we don't want more carbon in the air. The bacteria found in bokashi instead pulls carbon and nitrogen into the earth and makes it a kind of carbon sink.

A few years ago, almost nobody talked about bokashi, but during the last two years the method has gained a real boost in Sweden.

- Before, it felt like no one in Sweden had any control over what it was, but it really is no longer. It has been a very big change, she says.
