Sessions for schools 1. Recyclable and Compostable Waste

This session will enable students to identify the appropriate disposal route for household and school waste and introduce composting as a means of processing organic waste at home and  school. It is recommended that this session is offered with the Lunch Box session.

 Students are asked to name items of waste produced at home and school. These  are listed on a whiteboard or flip chart as they are identified

 A PowerPoint introduction to waste produced at school including cooked food waste and identifying those materials that can be recycled can be included.

  • Students working as a class or in groups are asked which items could be recycled   followed by which of the recycled group are biodegradable.
  • Brief explanation of composting
  • Identification of   those biodegradable materials that can be composted e.g.  Food waste, paper, cardboard, garden waste.

 This can be followed by a Group session where waste materials are sorted into those that can be composted in compost bins, composted in wormeries, composted by the local authority, recycled and sent to landfill. 

This practical exercise can be undertaken using:

  • The Compost Game in which plastic fruit, vegetable, cooked food and other (clean) waste e.g. cardboard, paper, plastics and tins are sorted into separate containers.

 OR

  • Using picture cards in which pictures of the above materials are sorted onto display boards or mounted walls.

OR

  • Using the lunch Box session chart shown in the picture

The whole class to come together to assess the results of the sorting exercise

Sessions for schools 2. Lunch Box Session

  Processing waste from lunch

In this short session Students indentify which of the leftovers from their lunches, including any packaging; can be composted, recycled or sent to landfill on the “Lunch Waste Log” provided. This compliments the Compostable and Recyclable waste session but using the actual waste produced by the students. The ideal session will be short as it is hoped that there will be little waste

A spare log can be provided for completion at a school lunch or a family meal at home. These logs can be discussed at school. If it is decided to continue this exercise at school the waste could be collected in a kitchen caddy and weighed each day and a class total per week can be recorded as a part of a waste audit.

Sessions for Schools 3. Compost Creatures and Safari

  Composting  recycles the nutrients that make plants (and animals) grow, feeds the bugs that keep the soil healthy and is a sustainable, low-cost way of dealing with organic waste  transforming it   into a valuable resource for the school or home  garden.

A compost heap isn't just a heap of dead stuff; it is a hotbed of biological activity.  One gram of compost can be home to literally millions of microscopic creatures.  The compost heap is a bit like a mini-beast nature reserve.

Our Compost Creatures and Safari session ( Compost Safari ) provides  children and interested adults in the East Midlands and the wider East Midlands with the opportunity to search compost from our compost bins and wormeries for the small creatures that help make and live in compost. The session also  includes a slide presentation, details of how to make a trap from plastic bottles and a quiz sheet  showing some of the  the creatures, from fruit flies to slow worms,  involved in the composting process or that might be found in a compost heap or bin.

Session 8 Compostable and Biodegradable materials

 Compostable Garden and school organic waste : Different Rates of Decomposition

This experiment enables students to record the decomposition rate of different plant materials including “clean food waste” from their snacks and lunches e.g.  bananas and apples , a range of vegetables such as  carrot and parsley peelings (sections of  roots may also be used), vegetable tops /leaves, herbs and plant compost “activators” such as comfrey and nettle leaves.  In addition to these “Greens” and range of “Browns” such as corrugated cardboard, tubes from kitchen rolls, cabbage stalks, twigs a autumn leaves if available. If unable to collect freshly fallen leaves a local gardener should be able to provided leaves from the top of their current leaf mould container

Each of the chosen compostable material is placed in its own labelled poly mesh produce bags (these are usually made from knitted plastic and have a drawstring closure. Net bags are used by farmers, gardeners e.g. onion bags  (A 310mm wide x 350mm long net bags are  available new from Polybags at about £19 for 100) ..

Each food bag should be buried in a compost bin or wormery, with a length of string attached to the draw string and reaching up to the top of the compost bin so it can be retrieved to be examined weekly.  

The depth at which the bag is buried in the bin should be noted so that it can be returned to the same position once photographed

On removal from the bin the   contents of each bag should be emptied on to  a  white card  marked with the date  and photographed  to record  the rate of  decomposition .

The weekly examination should be continued until all the materials have been decomposed.

 

Sessions for Schools 9. Composting with worms (a)

Background session on worms

This session forms an introduction to the sessions on composting with worms providing basic  facts (five hearts, no teeth or eyes, breath through their skin,  should be kept moist and like the dark, reproduction). Link to Cleopatra.

Sessions for schools 11. The Wiggo Pod

This experiment enables students to record the decomposition rate of a range of products sold as Compostable and Biodegradable

Biodegradable materials will eventually be broken-down by bacteria or other living organisms, while "compostable" products will  decompose under  aerobic conditions with controlled temperature and humidity.

There are two types of compostable material. Most  compostable products should  to break down in 2-3 months in industrial facilities.  Home composting labels indicate that the material can be composted at the lower temperatures that occur in home composting bins.

   

 

Compostable bags are often sold to be placed in kitchen caddies  to collect kitchen scraps for composting. When full of kitchen waste the bag is then  carried to the compost bin  dropped in avoiding the mess that might be associated with using an unlined caddy. Compostable bags can also be purchased for picking up dog mess. Compostable Cling film is also available

Disposable Compostable plates, bowls, food and drink containers sold as  composted are designed to be composting in municipal composting facilities not cool home composting systems. 

If a Hot Home composting system e.g. Hotbin, Green Johanna, Jorra , is available the effectiveness of this bin should be compared with the more common cool composting systems.

Each of the chosen compostable materials is placed in its own labelled poly mesh produce bags (these are usually made from knitted plastic and have a drawstring closure. Net bags are used by farmers, gardeners e.g. onion bags  (A 310mm wide x 350mm long net bags are  available new from Polybags at about £19 for 100) .

Each food bag should be buried in a compost bin or wormery, with a length of string attached to the draw string and reaching up to the top of the compost bin so it can be retrieved to be examined weekly.  

The depth at which the bag is buried in the bin should be noted so that it can be returned to the same position once photographed

Each week the compost bin temperature should be recorded.  The  bag should be removed monthly and the   contents of each bag placed on white card,  marked with the date and  bin temperature,  and photographed  to record  the rate of  decomposition  and the effect on it by composting temperature.

Sessions for Schools 12. Making Seed and Potting compost

In this session studnets make seed and/or potting composts using the mixtures given on the Seed & Potting Mixes page .

Seeds can be sown in the seed compost and their germination rates noted.

Seedlings can then be transpalented to a number of different mixes and their growth recorded photographically
