o At what frequency?<br />

o In what type <strong>of</strong> container?<br />

o With what type <strong>of</strong> incentive?<br />

o On what rounds?<br />

� Properly understood, collection systems need to consider each <strong>of</strong> these<br />

separately, not as though they were discrete questions demanding separate<br />

answers;<br />

� Options in respect <strong>of</strong> transfer points for subsequent bulking / onward transfer<br />

/ treatment;<br />

o How many will there be?<br />

o Where should they be located?<br />

Once again, these questions are connected to other questions concerning the nature,<br />

scale and type <strong>of</strong> treatment option to be used (ideally, the materials being collected<br />

are either treated where they are ‘bulked up’, or they are bulked up in such a way as<br />

to optimise the onward transport for subsequent treatment);<br />

� Options in respect <strong>of</strong> the treatment <strong>of</strong> materials;<br />

o Will any materials be composted at home?<br />

o Which materials will be re-used, and if so, to what use will they be put?<br />

o What type <strong>of</strong> mechanical separation technique will be used for dry<br />

recyclables if any?<br />

o If biowastes are being collected separately, will the treatment be<br />

aerobic or anaerobic?<br />

� If aerobic:<br />

• Will it be enclosed, or open air?<br />

• If enclosed, what type <strong>of</strong> technology will be used?<br />

• How long will the material be treated for?<br />

• What type <strong>of</strong> abatement equipment <strong>of</strong> exhaust gases will<br />

be used?<br />

� If anaerobic:<br />

• What type <strong>of</strong> treatment will be used?<br />

• What type <strong>of</strong> abatement equipment will be used?<br />

• Will the residue be treated in an aerobic phase after<br />

being digested?<br />

• How will waste waters be dealt with?<br />

o How will residual waste be treated?<br />

� Sent untreated to landfill?<br />

� Sent<br />

� Options in respect <strong>of</strong> the products manufactured from materials collected for<br />

recycling / composting / digestion<br />

o Are recovered recyclables manufactured into the same products from<br />

which they were derived?<br />

o Where will this happen (how far will they travel?);<br />

o To what use will compost / digestate be put, and what does this imply<br />

for ‘avoided products’?<br />

� Options in respect <strong>of</strong> energy generation;<br />

o Will biogas from landfills / digesters be used as:
