Figure5-2-8 Projections for Future Recycling · Reuse of Crystal Silicon Solar Cells and Modules

2010	2015	2020	2025	2030
Projected annual amount of disposal* (Existing EVA-containing modules)	< 5MW (500 tons)	10MW (1,000 tons)	100MW > (10,000 tons)	300MW (30,000 tons)	1,000MW (100,000 tons)
Reuse	For private residences	For disaster relief	For overseas	Accumulation center	New businesses?
Recycling by existing operators·Disposal·Collection of AI·Heating (burning of EVA) + Nonferrous smelting technology Collection of AI, glass and Ag	Less than 5MW
Recycling at dedicated PV factories·Based on existing technologies Collection of AI, glass, Si (Ag?)	Newly developed technologies Collection of AI, glass, Si and Ag	Factories capable of handling 20MW panels	Factories capable of handling 100 MW panels (New method of low-cost processing)

Note: The amount of disposal is projected on the basis of the actual introduction until 2004 and the projected introduction in 2005-2010 with the achievement of the 2010 introduction target of 4.82 million kW assuming disposal 20 years after purchase (See Figure 1-5-1).

We assume that existing EVA-laminated modules are sold until 2010 and subject to disposal is this type of modules.

## Figure5-2-9 Forestry Dairy

Effective utilization of abandoned satoyama, forested sites that need maintenance work, abandoned farmland, disused pastures, disused ski sites and golf courses, etc. →Value creation

Grazing of 0.5-2 cattle per hectare→Natural circulation of excrements is possible.

○Feed cattle with undergrowth in forests without depending on imported feedstuff

☐365-day, day-and-night yearlong grazing→No need for large cattle sheds

Natural mating, natural births, breast-feeding and long-term milking are the basis.

the problem of disposal of photovoltaic panels that is expected to come to the fore in the future in tandem with the penetration of photovoltaic power generation.

## ☐ Forestry dairy (Figure 5-2-9)

Company A is using unattended “satoyama” (community-based forest areas) to undertake natural grazing for “forest dairy” operations. The company is producing milk from dairy cattle that are pasturing and eating undergrowth in forests. Dairy cattle level the ground in forests and their excrements resolve into soil in forests, this cycle represents an integrated effort toward a sound material-cycle society and society in harmony with nature.

○ Blending of bicycle rental business and measures to cope with abandoned bicycles (Figure 5-2-10)

Company B is renting bicycles for students at about 120 universities across Japan by repairing bicycles abandoned at universities and commercial facilities to make them reusable. This can be described as an endeavor to blend efforts toward building a sound material-cycle society with measures to deal with abandoned bicycles.

## (6) Regional revitalization by leveraging sound material-cycle society businesses

○ Shinshu-type wooden guardrails (Figure 5-2-11)

The Nagano prefectural government certifies as Shinshu-type wooden guardrails those wooden guardrails that have such characteristics as (1) contributing to measures to prevent global warming; (2) using thinned
