You can define variables in the action block:

template:
  - trigger:
      - platform: time_pattern
        seconds: /10
    action:
      - service: calendar.get_events
        target:
          entity_id: calendar.waste_collection
        data:
          duration:
            days: 14
        response_variable: waste_events
      - variables:
          all_events: "{{ waste_events['calendar.waste_collection'].events }}"
          paper_ev: "{{ all_events | selectattr('summary', 'search', 'Paper', true) }}"
          food_ev: "{{ all_events | selectattr('summary', 'search', 'Food', true) }}"
          non_recycle_ev: "{{ all_events | selectattr('summary', 'search', 'Non-Recyclable', true) }}"
    sensor:
      - name: Food Waste Collection Events
        state: |
          {{ food_ev | list | count() }}
        attributes:
          scheduled_events: |
            {{ food_ev | list }}
          next_collection_date: |
            {{ (food_ev | first).start }}
          countdown: |
            {{ int((as_timestamp((food_ev | first).start) - as_timestamp(today_at('00:00')))/86400)}}

# And so on for each waste type...
