How do you remove odors from coffee grounds? What to do with coffee bean grounds?

Coffee grounds have many small pores, which have the effect of absorbing moisture and removing flavor. Storing dry coffee grounds in a cup and in the refrigerator or microwave can remove mixed odors from a variety of foods. It can be used in the toilet instead of chemical fragrances.

It also has a good deodorization effect in the wardrobe, shoe cabinet, and car.

There are several ways to make fertilizer from coffee grounds:

1.Coffee grounds can be applied directly to the pot, which can increase the organic matter content and slowly release nitrogen fertilizer to achieve the purpose of leafy growth.

2.The coffee grounds are left to dry in the sun, turned once a day, and after 5-10 days of dusting, they are dried as fertilizer.

3.The coffee grounds are allowed to ferment naturally, but the smell is strong and it is not suitable for making at home, so it can be operated in a pie place far away from the village.

4.According to the ratio of 1:2, it is added to the garden soil for fermentation, which can remove the peculiar smell, and it can also be fermented by adding plant leaves or young stems to ferment, and it can be decomposed after 30 days.

Disadvantages of composting coffee grounds:

Ordinary organic compost generally takes more than half a year, it can be done in 3 months, but it also has a disadvantage, that is, the fertility is too single, its main fertilizer content of nitrogen fertilizer, that is, the nitrogen content is very high, but the content of other phosphorus and potassium elements is very low.

Such soils are the best for the high-growth foliage plants, which are particularly fat, but are not suitable for flowering and fruiting plants because of the lack of phosphorus and potassium.

Tip 1: Exfoliate.

Coffee grounds are a good material for exfoliation, and rubbing and massaging the body with it and shower gel can remove the aging keratin, making it smooth and firm, delicate and shiny.

Trick 2: Moisture absorption and deodorization.

Coffee grounds have many small pores, which have the effect of absorbing moisture and removing flavor. Storing dry coffee grounds in a cup and in the refrigerator or microwave can remove mixed odors from a variety of foods. It can be used in the toilet instead of chemical fragrances. It also has a good deodorization effect in the wardrobe, shoe cabinet, and car. It is best to replace it every two or three days to avoid mold after absorbing water.

Trick 3: Natural fertilizers, pesticides.

A study by The Ohio State University in the United States found that coffee grounds contain about 2% nitrogen, which can convert organic matter into fertilizer, which is a safe and environmentally friendly fertilizer. Huang Yuming, an associate professor in the Department of Soil and Environmental Sciences at Chung Hsing University in Taiwan, pointed out that coffee grounds can be used dry or wet, as long as they are tiled on the top layer of the soil and allowed to decompose on their own, they can provide nutrients for plants, although it is not recommended for large crops.

In addition, since coffee grounds contain alkaloids, they can be used as natural pesticides. Dry and grind the coffee grounds first, then add water to re-boil, the brewed coffee water is cooled and then packed in a spray bottle, sprayed on the plant where there are insects, it has the effect of repelling insects, and it can be sprayed once in two or three days.

Whether it's the leftover coffee residues from self-brewing coffee or the coffee grounds taken back from the coffee shop, be sure to go through the drying step (except for damp coffee grounds that can be used for composting), if the balcony has enough space and sufficient sunlight, the exposure method is the most energy-saving and carbon-reducing way, spread on old newspapers, and dry naturally in about a week.

If it is not convenient to dry, you can put the wet coffee grounds into the pot and fry it until it is dry, and you can also remove the odor in the pot by the way.
