Green tips for your home: reduce your rubbish

Reduce your rubbish


You can implement many strategies to ensure your home is greener, environmentally friendly and less toxic, both for you and for the earth. This post will talk about reducing your rubbish load for your home to ensure it is greener and healthier for you, your family and your pets (if you have any).

It is really important to try to reduce your rubbish load to help reduce the amount of refuse and waste that is piling up in all of the rubbish dumps in countries all around the world. Some items of rubbish don't even decompose for many years and others get stuck in the waterways, poisoning and trapping wildlife.

Some tips on how to reduce your rubbish load:
  • Try to buy products that are re-usable instead of ones that are disposable - razors, cups, pens
  • Re-use your food packages - glass coffee jars, jams, juice bottles - these can all be re-used again and again, as storage for your other foods (just make sure you wash the bottles and jars properly after each use)
  • Buy fruit and vegetables loose, not in packets
  • Recycle your rubbish properly with recycling bins your local council provides and if you do not have the right ones or need more, request them
  • Compost your food scraps so that they do not need to go into your bins 
As you can see, there are so many ways to save the planet, which use up less energy, produce less pollution, save you more money and help your physical fitness. It's a win-win situation. So what are you waiting for?

    Advantages of buying organic food

    There are a number of really great advantages to buying organic foods (especially vegetables and fruits), over buying conventionally grown foods:

    1. Organic foods contain more nutrients
    Studies have shown that foods grown organically have more of the nutrients available in the foods, compared to foods grown conventionally.

    A report produced by the Organic Center and University of Florida reviewed 97 studies to compare the nutritional value of organic and conventionally grown plant-based foods (vegetables, fruits and cereals/grains). The authors of the review determined that the organic produce contained higher levels of eight of the ten nutrients reviewed. The review pointed out that the organic foods had much higher concentrations of a number of antioxidants and phytonutrients than the conventionally grown foods. The levels of the nutrients that were examined in the review were: vitamin A, vitamin C, vitamin E, phosphorus, potassium, four types of phytonutrients, protein.

    Additionally, other studies suggest that organically grown foods have higher levels of iron, magnesium than foods grown conventionally.

    2. Organically grown foods are better for the soil
    Organically grown foods, by definition are better for the soil, as they use gentle and well established farming methods, which are known not to harm the soils. Organically grown foods use natural fertilisers, natural pesticides and natural herbicides. Organically grown foods use companion planting, which greatly reduces the need for pest control of any kind. Organically grown foods encourages a healthy ecosystem which provides plant safe insects (such as lady beetles) for pest control (of aphids).  Organic farming potentially offers a means of returning functional evenness to ecosystems.

    3. Organically grown foods may help reduce incidence of cancer
    Many studies have shown that foods grown organically have much higher levels of antioxidant phytochemicals, such as anthocyanins, flavonoids and carotenoids than conventionally grown foods. Phytochemicals are very important nutrients, as they inhibit the proliferation of certain cancer cells by preventing the mutation of cells, which is how cancer spreads. Studies show that the higher the levels of antioxidants in the blood, the less likelihood of cancer. 

    The are a few, minor disadvantages of eating organic foods, which should be mentioned:
    • The cost of organic food can be more expensive than food conventionally grown and produced
    • Sometimes organically grown food (especially fruit and vegetables) can look a little less "perfect" than conventionally grown foods

    Advantages and disadvantages of raised beds vs traditional garden

    A small vegetable garden outside Austin, Texas

    There are a number of advantages and disadvantages to planting in either raised beds or a traditional garden and the use of one over the other, depends on a great number of factors.

    Planting in raised beds has a number of advantages: 
    • Provide an extended planting/growing season for the vegetables (generally)
    • Can be used instead of the soil in the ground if it is of poor quality
    • Weeds can be more effectively managed
    • The soil is not compacted and roots of the plants can flourish allowing better plant growth
    Planting in raised beds has a number of disadvantages:
    • There is a cost involved in purchasing the border/perimeter materials, which may not be so affordable for some
    • Less of the backyard will be utilised as the raised garden beds take up more room than a traditional garden patch
    • The more raised beds you have in your garden, the higher the costs will be to purchase the materials
    • It takes time to assemble and set up the raised garden bed before planting anything in there
    • Assembling and disassembling the garden bed material is often difficult and cumbersome if you want to move it to another part of the garden, or transport it to another home

    Planting a traditional garden has a number of advantages:
    • There are no extra costs associated with planting in the ground
    • Very easy to relocate the garden in different parts of the backyard
    • It's easy to find a spot for you garden, no precise measurements required, just dig where you want to plant your seeds/seedlings
    Planting a traditional garden has a number of disadvantages:
    • Planting/growing seasons is strictly limited to time frames within the season, not easy to extend past
    • Soil may be compacted which can cause some plants not to flourish well if their roots do not have freedom
    • Poor quality soil may not always be able to be reconditioned to a more appropriate state with fertilisers and other raw materials
    • It may be costly to try to invigorate poor quality soil to be acceptable for growing vegetables and fruits
